Motion Control Valves

Overcenter valves protect the consumer from cavitation and pressure peaks. Overcenter valves in poppet design can be used as hose rupture protection and keep the load safely at standstill. The back pressure at port 2 on the partially unloaded overcenter valve has no influence on the pressure limiting function.At thefully balanced overcenter valve, the control pressure requirement is independent of the back pressure. The fully balanced overcenter valve is available with separate discharge port 4.
