Firstly, industrial valves have a major role in a piping system. They typically perform five functions. Some valves are designed to have more than one. Some are multidirectional and multiport, allowing the media to flow in two or more directions. Others are used to regulate pressure or flow and relieve overpressure or increase pressure when a vacuum is present. Once you understand the basic role of a valve, you can find one that suits your needs.

The second important consideration is material. Forged steel valves are formed using mechanical equipment and extreme heat. This type is stronger and more durable than its forged counterpart. However, the additional labor and materials required make them more expensive. They are also prone to leaks, as the connections between different elements will not be as tight as they are meant to be. If you want your valve to last, you need to consider what it can handle.

The Different Types of Industrial Valves

If you are interested in buying a new valve, there are several different types to choose from. You can find them in most oil and gas generating companies, mining, sewerage system, and chemical manufacturing. Depending on your specific needs, you can choose a specific type according to the material of its body and the conditions of its operation. This article explains the different types of industrial valves to help you make an informed decision.

Valves by Disc Type

Disc Valves are widely used in all kinds of industrial applications, from high-pressure to low-pressure. They excel in both corrosive and viscous applications. The best valves for this type of fluid are stainless steel and forged iron. However, there are also additional features you may want to consider to ensure that you get the best fit for your project. Before choosing a valve, you should consider the temperature of the process fluid. If the valves are not suited for the temperature, your project will fail.

Valves by Body Materials

The different types of industrial valves are used for varying fluid flows in various industries. These valves simplify process control, increase safety and speed response time, and can be purchased in a variety of material grades and sizes. Most come with an air-operated actuator, which requires less ancillary equipment. You can buy one of these valves at your local industrial supply center. To learn more about the types of valves and their characteristics, read on.

Valves by Conditions

In order to choose the correct industrial valve for your process, you’ll need to determine the conditions the valve is intended to withstand. There are three basic types of industrial valves: flanged, ball, and butterfly. Each type is designed to withstand a certain set of conditions and the material that the valve is made of plays a major role in its performance.

Valves by Structure

It is not enough to understand the structure of valves in isolation; it is also important to understand how each part of the valve works. The extracellular matrix (ECM) provides support and physical strength to the valve cusps, as well as a framework for the cellular components. A series of proteins, known as integrins, bind to specific peptide sequences on the ECM. Valve interstitial cells express a1 integrins, a2 integrins, and b1 integrins. The connections between the integrins and the matrix serve as anchors for cells and stimulate the valves.

Industrial Valves Commonly Used in the Oil and Gas Industry

Industrial valves are important components of many processes. Here we’ll discuss four common types of valves used in the oil and gas industry: Ball valves, Globe valves, Gate and Butterfly valves. Each type has a unique function. There’s no one size fits all valve – check out the information below! 

In the oil and gas industry, the industrial ball valve is one of the most common types of valves. This type of valve is used in extremely high-pressure and high-temperature environments. Because of its high-temperature and pressure requirements, this type of valve is also subject to holes that can occur if molten steel is not formed evenly. Therefore, continuous monitoring and quality control are necessary to make sure that the valve operates as it should.

Gate Valve

In the Oil and Gas Industry, there are many different types of industrial valves. The first type is known as an upstream valve, and it controls the flow of crude oil or natural gas through pipes. Its role is to maximize flow while protecting the equipment in the process. Other types of valves are known as midstream or downstream valves, and they control the flow of oil or gas while dealing with high pressure and temperature.

Among the many types of valves used in the oil and gas industry is the butterfly valve. The butterfly valve is a quarter-turn rotating valve that allows a small disc to move in and out of its body. The butterfly valve is easily operated due to a gearbox that connects the handwheel to the valve stem. These valves have an easy opening and closing process and require minimal maintenance. Butterfly valves are also available in small and large sizes. They have low operating and maintenance costs and are capable of handling high-pressure fluids and gases.

Globe Valve

Globe valves regulate flow within a pipe. They work in turbine lube oil and cooling water systems. They offer excellent shutoff capability and have a wide range of applications. Globe valves can be found in angle, tee, and wye patterns. These valves are used for shutoff and regulating flow in pipelines. A globe valve’s main benefits include shutoff ability and low-pressure drop.

A gate valve is a linear motion valve that is primarily used for blocking or isolating media. It is less effective for controlling flow, as it requires a completely open state to prevent leakage. Gate valves are commonly used in industrial oil piping systems, irrigation networks, and marine industries. Non-rising stem gate valves are also popular on ships. Gate valves are less durable than globe or ball valves and are more susceptible to leakage.

Check Valve

The Check Valve is a common type of industrial valve used in the oil and gas industry. This type of valve is made up of three main parts – a disc, a spring, and an actuator. Each component works independently to keep the valve open and prevent backflow. They are inexpensive and simple to install and do not need manual operation. Most types are automatic and require no human interaction.

Plug Valve

A Plug Valve is a type of valve that has a large number of applications in chemical and petroleum services. Its port is shaped to fit the size of the piping system, and the port shape determines the overall style of the valve. Other common types of port connections include compression, threaded, barbed, flanged, and socket weld. The valve’s seat material and seal material determine how it fits into the piping system.

The Plug Valve is typically a two-part system that has an open and a closed position. The rotator controls the flow by rotating internal components. In the closed position, the plug valve will close completely. However, the plug valve’s small area means that its operation is not as efficient as a ball valve, and it is only effective in a horizontal flow. It also suffers from a significant pressure drop due to the reduced area of its port.

What is WOG For Valves?

WOG For Valves is a term used to describe a valve’s pressure rating. This rating refers to the maximum pressure the valve can withstand while working in either water or oil. In general, the higher the WOG rating, the better the valve will perform. However, you may find that some valves have higher pressure ratings than others. If this is the case, you should read the manufacturer’s manual thoroughly before purchasing a new valve.

When looking at a valve’s WOG rating, remember that the CWP designation stands for “Cold Working Pressure” and indicates the pressure rating for the valve at 100 degrees Fahrenheit. For example, a valve that has a CWP of 600 represents a WOG of 600 PSI. Alternatively, a valve with a WOG of 1000 is a “1000 PSI” valve.

What Are API Standards?

The American Petroleum Institute (API) created and maintains industry standards that are designed to help ensure a high level of reliability and safety in the oil and gas industry. The standards cover topics such as materials, design, manufacture, testing, and marking of parts. Using API standards can speed up product development, reduce costs, and minimize confusion. They are also more easily accepted by international and state regulators.

For example, API 6D defines the requirements for the design and manufacture of a gate valve. The design also includes an extra corrosion allowance, which is reflected in the thickness of its walls. These specifications also stipulate the dimensions of the valve. If the valve is used in a “sour” environment, the NACE MR-0175 standard will apply. The API 600 standard details important dimensions for gate valves.

The specifications for these industrial valves are very specific for the specific application they’re designed for. These valves are used to control the flow of oil and gas in various types of wells. In some instances, the valves are able to handle entrained particulates, abrasive media, or sour gas. The valves in these environments are expected to handle the harshest operating conditions. API monograms can be found on many types of valves.

Gas valves are flow-controlling equipment that is crucial in any pipeline system. They are used to manage, regulate, and control the flow rates of gases like natural gas, oxygen, and liquid hydrocarbons in the oil and gas industry.

Valves are also used to avoid backflow, manage fluid pressure, segregate and safeguard devices, and direct the crude oil refining. Gas valves come in several elements (plastic or metal) and for a diversity of fluids (liquid, gas, corrosive, toxic, flammable, etc.), uses (control, on/off), and temperatures to meet a wide range of applications and situations.

This article will go over 9 essential valves used in the oil and gas sector.

Plug Valves:

Plug valves are 'plugs' that can be adjusted within the valve body to start or stop the passage of fluid through the valves or pipelines. When the valve is open, the plug valve typically has one or more openings that allow fluid to flow freely.

Advantages:

• Plug valves are easy to use and often cost less.

Disadvantages:

• Because of the lowered outlet, they are smaller and have a low resistance flow.
• The following are some examples of common plug values in the oil and gas industry:
• Plug valves that have been lubricated
• Plug valves that are not greased
• Plug valves with a central position
• Plug valves that expand

Bellow-Sealed Valves:

Steel bellow-sealed valves are widely utilised due to the valve stem's internal design and radial movement. Bellow-sealed valves are divided into two categories:

Advantages:

• Low-pressure fall, quick-acting, right through flow in both directions, efficiently operated bubble-tight shutoff, and working torque.

Disadvantages:

• Seating material has a long "relative" face-to-face size and thermal restrictions.

Gate Valves

When a straight-line fluid flow with minimal flow resistance is required, the gate valve's function is to start or halt the flow.

Gate valves are maintained wide open or fully closed during use. The plate is removed when the gate is opened, enabling items to pass through.

• Gate valves come in a variety of shapes and sizes.
• Slab gate valves in pipelines
• Slide gate valves in parallel

Wedge gate valves

Advantages:

• A low-pressure decrease and a straight-through passage of fluid in any direction.

Disadvantages:

• It is slow-acting and takes up a lot of room. It is not a drip-tight seal.

Check Valves

Non-return valves are sometimes known as check valves. Check valves, unlike other manually operated valves, work automatically. Constantly maintaining fluid moving in one direction avoids back-flow in the pipework.

The following are examples of popular check valves used in the oil and gas industry:

• Check valves that swivel.
• Check valves for pistons.
• Check valves with balls.
• Check valves with a tilting disc.

Pressure Seal Valves

This valve is utilised for high-pressure service, as the title indicates. Over 170 bar pressure sealing valves are commonly used. For raising internal pressure and sealing the valve and pressure seal gasket, it comes with a pressure seal bonnet and a fastened bonnet.

Butterfly Valves 

The butterfly valve is a fluid separation device that operates at an angle to the stream.

Butterfly valves offer somewhat lowered flow characteristics and provide bubble tightening with minimal operating torque due to the wing-like movement of the disc.

Advantages:

• Tiny and lightweight, highly efficient, fundamental and dependable, with strong regulating properties and low-pressure isolation.

Disadvantages:

• Even when fully expanded, some disc sections are constantly exposed to the flow.

ORBIT Valves

ORBIT valves can operate between -104 and 427 degrees Celsius, making them excellent for mole sieve dryers and hot liquid systems.

Solenoid Valves

Solenoid valves are electromechanical device-driven valves that produce a strong magnetic field. They are being used to control gas or liquid flow in a pipe (open, close, distribute, mix).

Because they do not emit a substantial amount of methane, they are commonly employed in the oil and gas industry.

Components Of A Flow Control Valve

The following are the significant features of a control valve:

• The modifying element is enclosed and operated within the valve body.
• The positioner is a component positioned on the valve body and is used to regulate the extent of valve opening.
• The actuator is the mechanism that moves the valve's modulator component, such as the ball (ball valves), the disc (butterfly valves), or the stem (stem valves) (globe valves)
• The controller

Categories Of Flow Control Valves

Depending on the stem movement, control valves can be divided into two categories:

• Reciprocating/linear motion
• Globe, diaphragm, and pinching control valves (straight, angle, 3-way)

The stem of the rotary machine:

• Types of control valves include ball, butterfly, and plug.
• Single-seat or double-seat globe control valves are available.

Selection Of Control Valves

When choosing the proper control valve, process engineers must examine several parameters. The following are the general selection factors to be considered:

• The form of control, the degree of power, and the degree of the shutdown are all factors to consider.
• Allowable pressure drop; maximum temperature; design pressure
• Other qualities, such as fouling or coking, include fluid corrosivity, fluid erosion properties, and other parameters.
• Valve Cv has inherent properties such as leakage hazard, heat or cold conservation, and cost.

Final Thoughts

Oil and gas demand is constantly increasing, and processes have become more complicated over time. Valve quality is essential in oil and gas transportation because it can help minimise methane gas emissions while in transit.

As the oil and gas business continues to be concerned about global warming, productivity demands are now more significant than ever. Control valves are necessary for regulating fluid flow rate in a pipeline and lowering the percentage of emissions.
