Marchesini VBCD SE A CC single-acting overcentre valve, for closed centre.
The VBCD SE A CC is the type A single overcentre valve for closed-centre directional valves. It holds the cylinder in one direction, lets the load come down in a controlled way and limits the pressure in case of shocks. It is not sensitive to back pressure, so it works where a normal overcentre valve does not control the load properly.
Maximum pressure 350 bar and pilot ratio 1:4.5. C1 goes to the free-flow side of the actuator and C2 to the held side; V1 and V2 go to the directional valve. Set it at least 1.3 times above the pressure caused by the load.
