OM VBPDE 1/4" A DOUBLE PILOT OPERATED CHECK VALVE
V0178 1/4” BSP – Double pilot operated check valve (Type A)
Product description:
The V0178 type VBPDE A 1/4” double pilot operated check valve (Type A) is designed to securely lock hydraulic cylinders in both directions. The valve allows free flow in one direction while blocking flow in the opposite direction until pilot pressure is applied. It is suitable for load holding and precise position control applications in hydraulic systems.
Main features:
- Type: VBPDE A – double pilot operated check valve (Type A)
- Code: V0178
- Connections (V1–V2 / C1–C2): G 1/4”
- Maximum flow rate: 20 l/min
- Maximum operating pressure: 350 bar
- Pilot ratio: 1 : 5.5
- Cracking pressure: 4.5 bar
- Weight: 1.032 kg
Operating Principle
This valve contains two integrated check valves that allow flow in one direction while preventing reverse flow. However, when pressure is applied to the pilot port, it opens the opposite check valve, enabling controlled bidirectional movement.
This makes it especially useful in actuating hydraulic cylinders where movement should only occur under specific, controlled pilot pressure. Essentially, it prevents unwanted drift or motion in hydraulic actuators unless an intentional signal is given.
