Anyone know about hydraulic systems?

Hi Guys,
I borrowed a friends log splitter a few weeks ago and used it to split up 6 cords of fresh cut eucalyptus. It worked great up til two days ago.

Contact us to discuss your requirements of hydraulic pressure relief valve. Our experienced sales team can help you identify the options that best suit your needs.

Now it only develops 300 psi of pressure (measured at the inlet to the valve with a teed in pressure guage. When I started using it, if I overloaded the ram it would bog down the motor til it stalled. Now the motor sounds like it is hardly working. Also the problem developed after letting the machine sit idle overnite. It was not a gradual weakening of pressure.

I checked the hydraulic oil in the tank, changed the filter and bled the ram. I disassembled the two stage pump and saw no evidence of a problem

The valve doesn&#;t seem to have a overload pressure relief (at least not one that looks like my kubota&#;s loader valve does) but I am thinking the valve is the culprit at this point.

Before I disconnect all the fittings and hoses and start in on a unknown project I thought I would solicit all your advice.

I don&#;t even know if a cheap hydraulic valve is repairable or if I should just buy a replacement.

The splitter is a mtd yard machines with a vertical shaft motor that looks to be about 5 hp.

It is rated at 20 tons. The control valve has the name &#;energy&#; stamped on it.

The awkward part is my friend now needs the splitter himself and consequently I want to repair it as quick as possible.

Thanks,
Karl

All You Need to Know About Pressure Reducing Valves

A pressure-reducing valve, or PRV, is a comparatively small but incredibly powerful component that can have an impact on the entire house. This significant plumbing valve is intended to control the water supply to infrastructure at the point when it enters the home from the nearby utility. A correctly working pressure-lowering valve can lower monthly costs, lengthen the life of water-using appliances, and extend the useful life of a home's entire plumbing system.


What is a PRV?

Pressure-lowering valves convert the high water pressure that is coming in from the outside into a lower, appropriate pressure for a residential building. They are often mounted near the shut-off valve on the main water supply line.

The pressure is reduced to the correct level as the water exits the valve via the other end as it travels past the diaphragm, which is coupled to a spring.

Within the parameters of its design, a reducing valve may also be adjusted to any preferred downstream pressure. Once the valve is fixed, the decreased pressure will be preserved despite variations in the system load and changes in supply pressure.


Why Do You Need a PRV?

Not every residence has a PRV. A new home or a renovated home is not obligated to include a PRV if the inbound water pressure is less than 80 pounds per square inch  (psi) in accordance with the Uniform Plumbing Code (UPC), which is the main reference for plumbers and construction agencies in the Denver-Boulder area as well as across the country. Additionally, some municipal water utilities are frequently unable to formally record such high pressures on a regular basis to support requiring PRVs. Nonetheless, a growing number of new homes must comply with them due to updating municipal requirements.

High water pressure can put pipes under a lot of strain, which might break them or weaken the pipe fittings and result in leaks. Therefore, pressure-reducing valves can extend the lifespan of pipes and prevent plumbing fittings from exploding.


What Are the Benefits of PRV?

The advantages of having a fully working, adjustable PRV for residential homes are numerous. One of the benefits of installing a PRV is having less water usage compared to the typical consumer. As a result, a PRV can financially help by saving more money than without one. Additionally, PRVs can easily meet standard requests for a little more or slightly less water from the tap while also saving money on water usage.

Furthermore, faucet seals and shower nobs and levers will all operate at better lifespans because of the reduced strain at a lower water pressure. The copper pipes and fittings in household drainages will also often last longer with a PRV because of the decreased rate of corrosion at a substantially lower pressure.


How Does a PRV Operate&#;

On a property, a water pressure regulator valve is usually situated close to the main water shutoff valve. To raise the overall pressure in the valve, pressure regulators have a spring component that can be adjusted with a tool. Before the water is supplied to the fixtures and appliances around the house, the inbound water pressure from the primary water pipe will be reduced once the spring is tightened.

The pressure regulator valve's spring, on the other hand, can be relaxed to raise the hydraulic pressure in the infrastructure. The cutoff valves on the property will last longer a pressure regulator. Furthermore, a  pressure valve is also intended to reduce pressure on an appliance's internal valves. Professionals use this valve to remove differences in hydraulic pressure in households.


3 Types of Issues With Water PRV

Anything exceeding 80 psi of excess water pressure can seriously harm a home's plumbing system. In the end, this pressure can harm water-using equipment and potentially cause leaks and the water hammer issue. Fortunately, by putting a set pressure valve on the main water line, maintaining a safe level of water pressure can be easy.

A pressure regulator valve, as its name suggests, limits the water pressure to a safe level specified by a plumber. Although useful, this plumbing part could experience issues over time. 

  • Defective Components

A temperature-resistant diaphragm that is attached to a spring and integrated with a water pressure decreasing valve. Whenever the fluid pressure is too high, the diaphragm will close tightly. The diaphragm will trigger the spring system to open if the water pressure entering the system is too low. Regardless of whether a water pressure regulator valve is made of sturdy materials, its internal parts will eventually start to fail.

  • Clogs

It is possible to increase or decrease the water flow through the pressure-lowering valve by turning a screw located at the top. The volume of water that's also circulated to any household's faucets and appliances will be reduced overall as the screw is tightened. To demonstrate, simply release or tighten the screw to adjust the water pressure in any designated room. Thus, low water pressure in a home is an indication that the water pressure regulator valve is clogged.

  • Wrong Pressure Setting

The pressure provided to the internal spring mechanism of water regulator valves can be changed using a screw that is built within the valve. Water flowing through the diaphragm will be more difficult once the screw is tightened. On the contrary hand, the opposite outcome will occur if the screw's pressure is released.

A pressure drop adjustment on the pressure reduction valve could be the cause of the low water pressure. It is possible to change the valve to boost the water pressure in any dwelling. Most reducer valves have a predetermined maximum pressure rating of 50 psi. Fortunately, a qualified technician can quickly alter the maximum pressure rating.


Conclusion

The secret to keeping a home's plumbing in good shape is to have adequate water pressure. High water pressure will eventually wear out practically anything that interacts with the drainage system if it is not controlled.

It is possible to save money in the long run by maintaining the water pressure in the system and having a functioning pressure-lowering valve.
