Single Overcentre Valve - Partially Balanced

These valves are used to control the actuator movements and block it in one direction. In order to have the descent of a load under control and avoid the load’s weight being carried away the valve will prevent any cavitation of the actuator. The valve setting and pilot pressure is insensitive to back pressure. The valve is used in combination with a closed centre control valve.

MATERIALS AND FEATURES:
Body: zinc-plated steel.
Internal parts: hardened and ground steel.
Seals: BUNA N standard.
Leakage: negligible leakage.
Standard setting: 320 Bar.
Valve setting must be at least 1.3 times more than load pressure in order to enable the valve to close even when subjected to the maximum load pressure
