All About Hydraulic Check Valves

Hydraulic check valves are the most widely used valves that allow fluid to flow in one direction in the hydraulic system and prevent reversal of fluid flow.

That's why the name "valve". In other words, this device is installed in the pipe so that water does not flow back into the pipe.

There is a mechanism in the pipe that moves according to the flow of water to the valve, and when needed, the mechanism attaches the valve opening so that there is no backward flow of water.

In hydraulic check valve, there are two holes. The inlet through which the hydraulic fluid enters and exits through which the liquid exits. The best thing is they operate automatically.

They work related to hydraulic pumps, motors, and cylinders. The valve controls the flow and pressure of the fluid so that the equipment is functioning properly.

There are various designs available in hydraulic valves such as balls, plungers, swing disks and poppets. Depending on the application area, the size and shape vary.

These check valves are used in industrial applications that require hydraulic pumps, such as automotive braking systems, vehicles, construction equipment, including municipal water and sewer systems. They are used in systems where fluid reserves can cause problems on a large scale.

Hydraulic valves are used for various reasons such as the following:

  • The vital role they play is to prevent flooding if there is a backflow of water flowing through the pipe.
  • They prevent engine damage from running water in the wrong direction.
  • When the engine is turned off, the valve helps prevent fluid from flowing back in the wrong direction. Instead, they save power and also protect pipes from water damage.
  • They allow the flow of liquid in one direction.
  • They control fluid pressure.
