OM VBCD 3/8" DE-A DOUBLE OVERCENTRE VALVES
V0422 3/8” BSP – Double-acting counterbalance and load holding valve (DE A)
Product description:
The V0422 VBCD 3/8” DE A double-acting counterbalance and load holding valve is designed to control and securely hold hydraulic actuators in both directions. The valve ensures controlled lowering of the load, preventing runaway caused by the load’s own weight and avoiding actuator cavitation. The “A” type configuration features a different port layout and pilot ratio, making it suitable for specific installation requirements.
Main features:

- Max. flow rate: 40 l/min
- Maximum operating pressure: 350 bar
- Pilot ratio: 1 : 4.5
- Standard pressure setting: 320 bar
- Housing material: Steel (zinc-plated)
- Weight: 1.97 kg
Working Principle
This double overcenter valve operates on both directions of a double-acting cylinder, regulating return flow only when pilot pressure is applied. It maintains load stability by locking the actuator in place until commanded otherwise, preventing uncontrolled movement due to external forces or gravity. Each side includes a check valve and a pressure relief circuit, allowing smooth and safe motion control.
This design minimizes hydraulic shocks, enhances equipment safety, and is ideal for systems where load holding and precise control are critical.
