OM VBCD 3/4" DE-A DOUBLE OVERCENTRE VALVES
V0435 3/4” BSP – Double-acting counterbalance and load holding valve (DE A)
Product description:
The V0435 VBCD 3/4” DE A double-acting counterbalance and load holding valve is designed to control hydraulic actuator movement and to safely hold loads under pressure in both directions. The valve ensures controlled lowering of the load, prevents actuator cavitation, and avoids runaway caused by the load’s own weight. The DE A configuration features a different port layout and pilot ratio compared to the standard version.
Main features:
- Type: VBCD – double-acting counterbalance and load holding valve (DE A version)
- Part number: V0435
- Connection (V1–V2 / C1–C2): G 3/4”
- Max. flow rate: 100 l/min
- Maximum operating pressure: 350 bar
- Pilot ratio: 1 : 5.5
- Standard pressure setting: 320 bar
- Housing material: Steel (zinc-plated)
- Weight: 3.8 kg
Operation Principle
An overcenter valve controls the movement of hydraulic actuators while preventing backflow, acting as a brake. It stays closed by default due to an internal spring, only opening when a sufficient pilot pressure is applied this ensures loads do not move unless intentionally activated.
The dual configuration allows it to manage flow in both directions, providing secure and controlled descent or movement. This system is crucial for maintaining stability and preventing free-fall or drift in load-handling applications.
