A solenoid valve is an electrically activated valve, typically used to control the flow or direction of air or liquid in fluid power systems. Solenoid valves are used in both pneumatic and hydraulic fluid power systems, and most often in either poppet or spool configurations.

The spool or poppet of the valve is connected to a ferrous metal plunger, which is typically spring centered or spring offset. The plunger slides within a core tube of non-ferrous metal, which itself is surrounded by a coil of electrical windings. The coil can exist as any range of voltage from 12-48 V dc to 110-220 V ac. When power is sent through the coil, a magnetic field is created that pushes or pulls the plunger, shifting the valve.
The most basic solenoid valves are two-way, two-position poppet valves, which simply open and close to allow flow when their coil is energized. They are available as &#;normally-open&#; and &#;normally-closed&#; versions, which means normally-flowing and normally-blocked, respectively. Normally-open in fluid power is the opposite of normally-open in electronics, which means the switch or contact is open and not flowing electrons.
Three-way, two position poppet valves are also common, allowing fluid to be diverted from one channel to another. Two 3/2 valves in parallel can be used to control and cylinder bi-directionally. Although construction varies depending on the use, this type of valve can be used for either pneumatics or hydraulics.
Spool solenoid valves consist of a machined spool that can slide within a machined valve body. Each end of the spool can have a plunger attached, allowing the solenoid valve to be pushed in either direction, allowing three positional envelopes. The 4/3 hydraulic solenoid valve is one of the most popular, allowing for bidirectional control of a cylinder in a single valve body. The &#;ways&#; of a solenoid valve refer to how many ports it contains, and the &#;positions&#; of a solenoid valve refer to how many states it can operate within. A three position valve requires a spring centered neutral state along with two actuated positions.
Pneumatic valves are available as five ported valves, allowing for a 5/3 solenoid valve for control of cylinder applications. The ways of a pneumatic valve also include its exhaust port, to which there are usually two.
Solenoid valves for either hydraulic or pneumatic applications are available as manifold-mounted modular units, such as the pneumatic or hydraulic ISO valves. These valves contain standard mounting and porting patterns, allowing valves from any manufacturer to be installed upon the same manifold. Most often, these valves are also quite economical, and readily available &#;off-the-shelf.&#;
The coils of a solenoid valve can be had with DIN connectors, lead wires, Deutsch connectors or any other popular form of electrical connection used in fluid power and automation. Solenoid valves often have removable coils, allowing quick and easy replacement after they fail. Coils also have a wide range of application and purpose. Some are intended for the industrial environment, where atmosphere conditions are consistent. Mobile environments are much more demanding, and require coils that can both handle extreme temperature ranges and exposure to road film and salt.

Solenoid Valve Market Segment Analysis - By Usage
In a hydraulic system, a hydraulic solenoid valve is a solenoid-controlled valve that opens, shuts, or adjusts the direction of liquid flow. Various chambers, also known as ports, make up the valve. The solenoid opens and shuts the ports by moving the spool inside the valve. Directional control valves, pressure control valves, and flow control valves are the different categories of hydraulic valves. The flow in the hydraulic system is directed in a specific direction by directional control valves. They have the opportunity to disrupt or restart fluid flow. Inside a hydraulic circuit, directional control valves may adjust the flow path of a fluid. When the fluid flows through the system, pressure reduction valves reduce/relieve the pressure. They make sure that the fluid pressure remains below the fixed level, avoiding potentially risky scenarios. They can be found in a variety of circuit components. In hydraulic systems, flow control valves regulate the rate at which fluids flow. This is done by using a tapered orifice to open and close. Higher or lower flow rates occur as a result of this. Flow control valves with compensating and non-compensating functions are generally deployed. Non-compensating flow control valves respond to changes in inlet and outlet pressure, while compensating flow control valves do not adjust to variations in the pressure. Hydraulic solenoid valves are widely used in industries like manufacturing, aerospace, construction and many others that require hydraulic systems.
Solenoid Valve Market Segment Analysis - By Application
Automotive sector market is estimated at $432 million in and is projected to grow at 2.1% CAGR through . In automotive industries, solenoid valves are used in air intake systems, fuel injection and ignition systems, exhaust systems, HVAC body, body controls, locking and safety systems, engine control, cooling, lubrication, steering, suspension, transmission systems. In addition to these, they are also used in security systems, automatic gearbox drive selectors, air conditioning controls, and so on. For instance, the solenoid valves plays an active role in starting system of the automobiles like cars and trucks. The current is passed from the battery of the vehicle to the solenoid valve, when the user turns on the ignition switch of the automobile. This pushes the solenoid valve to close the heavy pair of contacts that enables the flow of the current to the starter motor of the vehicle. The starter motor brings about the initial motion of the piston inside the cylinder before the piston achieves self-actuating motion due to burning of the fuel inside the cylinder. Once the engine starts, the user stops the further motion of the ignition switch, due to which the flow of the current to the solenoid valve and therefore the starter motor is stopped. If the current flow to the solenoid is not sufficient then the contacts are not closed and the vehicle fails to start. Generally, this happens when the battery is low or damaged or if there is any problems in the cables. The automotive industry is growing at a healthy rate globally with demand coming primarily from the emerging countries, and the production shifting to these areas. Global automotive industry has been enjoying a period of relatively strong growth and profitability, and in few regions the annual sales have reached prerecession levels.

Solenoid Valve Market Challenges
Shutdown of Oil Rigs
In Oil and gas industries, solenoid valves are used in upstream, midstream, downstream activities of oil and gas industries. The upstream consists of activities such as exploration and extraction of crude oil, whereas downstream consists of activities such as filtering and purification of oil and gas. Solenoid valves are one of the key resources required in the Oil & Gas industry. They are used in wide range of applications ranging from drilling an oil well to extraction and transmission of crude oil such as in heating systems, control systems, safety systems, fractional distillation, catalytic cracking and so on. Thus, they have witnessed significant adoption. However, the potential decline of the demand for fossil fuels and oil has led to an economic downturn for the sector including the shutting down of a number of oil rigs. Although this slowdown has reduced, the demand will continue to decline over the forecast period thereby resulting in low growth in the solenoid valves market.
