All About Hydraulic Check Valves
<!-- @page { size: 8.5in 11in; margin: 0.79in } P { margin-bottom: 0.08in } -->
Hydraulic check valves are the most widely used valves that allow fluid to flow in one direction in a hydraulic system and prevent reversal of liquid flow. That is why the name the "check valve". In other words, this device is installed in a pipe so that the water does not flow backwards inside the pipe. There is a mechanism inside the pipe which moves according to the flow of the water towards the valve, and when required, the mechanism plugs up the valve opening so that there is no flow of water backwards.
In a hydraulic check valve, there are two openings. The inlet through which the hydraulic fluid enters and an outlet through which the fluid goes out. The best thing is that they operate automatically. They work in relation with hydraulic pumps, motors and cylinders. The hydraulic check valves control the flow and pressure of the fluid so that there is proper functioning of the equipment.
There are different designs available in hydraulic check valves like ball, plunger, swinging disc, and poppet. Depending on the application area, the size and shape varies. Hydraulic check valves are used in industrial applications that require hydraulic pumps, like in automotive braking systems, vehicles, construction tools, including city water and sewer systems. They are used in systems where a backup of fluid could cause problems on a large scale.
Hydraulic check valves are used for different reasons such as follows:
- The vital role they play is that they prevent flooding if there is extreme back flow of water running through the pipes.
- Hydraulic check valves prevent the damage of the machine from water flowing the wrong direction.
- When the machine is turned off, the hydraulic check valve helps in preventing the fluid from flowing back in the wrong direction. In return, they save power and also protect the pipes from water damage.
- They allow liquid flow in one direction.
- They control fluid pressure.

What is the function of a check valve kit on a Moen kitchen faucet?
My faucet kept stopping when water pressure got too high - I removed the check valve kit and it seemed to fix the issue. By removing, am I causing other issues? Should I be replacing it?
pretty sure your moen has a life time warranty, so they would probably mail the part to you,
