OM VBCD 1/2" SE FL SINGLE OVERCENTRE VALVE
V0402 1/2” BSP – One-way counterbalance and load holding valve (flange-mounted)
Product description:
The V0402 VBCD 1/2” SE FL one-way counterbalance and load holding valve is designed to control hydraulic actuator movement and to safely hold loads under pressure. The valve ensures controlled lowering of the load, preventing actuator cavitation and runaway caused by the load’s own weight. Its flange-mounted design allows direct installation onto the actuator.
Main features:
- Type: VBCD – one-way counterbalance and load holding valve, flange-mounted design
- Part number: V0402
- Connection (V1–V2): G 1/2”
- Max. flow rate: 60 l/min
- Maximum operating pressure: 350 bar
- Pilot ratio: 1 : 4.5
- Standard pressure setting: 320 bar
- Housing material: Steel (zinc-plated)
- Weight: 1.212 kg
Working Principle
This overcenter valve allows free flow in one direction via an internal check valve but restricts flow in the opposite direction unless a pilot pressure is applied. This design prevents uncontrolled load movement, such as dropping or overrunning of cylinders under load. The valve opens only when the pilot pressure reaches a preset ratio, ensuring that movement begins only under controlled conditions.
This makes it a crucial safety and control element in systems where precise load holding and gradual release are essential.
