Hydraulic check valve “lock” VBPSL  3/4” for single-sided actuator controlled by remote control. 

It is widely used in hydraulic systems in agriculture, construction and industry.

The valve is suitable for various types of machinery such as aurochs, cyclops, agricultural and industrial machinery, forklifts and other hydraulically operated equipment.

It is ideal for protecting against sagging cylinders that are subjected to prolonged stress. For example, on a TUR front loader, it protects the main frame from spontaneous dropping.

Controlled check valve is used to block the flow of oil in one direction, in the opposite direction the flow is free. The valve gives the possibility to remove the blockage by remote control, which is controlled by pressure.

Connection:

The flow is free from V to C, while blocked is from C to V.

The flow from C to V unlocks when pressure is applied to the pilot.
