VBPDE CIL twin pilot operated cylindrical check valves

What is a cylindrical twin pilot operated check valve?

A cylindrical twin pilot operated check valve is a specialized hydraulic component that allows fluid flow in one direction while, thanks to the pilot function, ensuring controlled return of the medium in the opposite direction. This solution combines the functionality of two check valves and a pilot piston, creating a compact and extremely effective design. This valve features a construction based on two flow paths and a check mechanism with a pilot piston. Thanks to this design, the valve can work independently on two supply lines, allowing for the simultaneous protection of two hydraulic circuits. The pilot cylinder activates the opening of the valve in the opposite direction after an appropriate hydraulic signal is provided. The valve body is usually made of steel or cast iron, which ensures high resistance to pressure and mechanical damage.

Application of the twin pilot operated check valve

These types of valves are primarily used in the hydraulic circuits of double-acting actuators, where it is necessary to maintain the actuator's position under load. Thanks to the ability to control the flow direction, these valves also serve as protection against uncontrolled actuator movement in the event of a power failure. They are particularly useful in systems requiring a high level of safety and precise motion control.

Industries where the valve is used

The cylindrical twin pilot operated check valve is widely used in:

• mobile hydraulics (construction, agricultural, forestry machinery),

• heavy industry,

• lifting systems,

• industrial automation,

• hydraulic systems of cranes and hoists.
