Use And Operation

These valves are used to control actuator's movements and block in bothdirections in order to have a under control descent of a load; load's weight doesn't carry it away, as the valve prevents any cavitations of the actuator.This valve is ideal when normal overcentre valves doesn't work properlyas it's  not sensitive to back pressure. They allow to work in series with more movements.

Aplikācijas

Connect V1 and V2 to the pressure flow, C1 and C2 to the actuator to be controlled
