OM VBCD 1/2" SE SINGLE OVERCENTRE VALVE
V0410 1/2” BSP – One-way counterbalance and load holding valve
Product description:
The V0410 VBCD 1/2” SE one-way counterbalance and load holding valve is designed to control the movement of hydraulic actuators and to safely hold loads under pressure. The valve ensures controlled lowering of the load, preventing runaway caused by the load’s own weight and avoiding actuator cavitation. Its in-line design allows for easy installation in hydraulic circuits.
Main features:
- Type: VBCD – one-way counterbalance and load holding valve
- Part number: V0410
- Connection (V1–V2): G 1/2”
- Max. flow rate: 50 l/min
- Maximum operating pressure: 350 bar
- Pilot ratio: 1 : 3.1
- Standard pressure setting: 320 bar
- Housing material: Steel (zinc-plated)
- Weight: 1.13 kg
Operating Principle
This overcenter valve works by allowing free flow in one direction (toward the actuator) while controlling flow in the opposite direction based on pilot pressure. When a load tends to run away or move due to gravity or momentum, the valve holds it in place until the pilot pressure from the control circuit opens it intentionally.
The built-in check valve allows fluid to pass to the actuator, while the overcenter function ensures safe and smooth lowering or return movement. This design prevents uncontrolled drops, especially in vertical lift systems like cranes or loaders.
