Válvulas de doble centro para centro cerrado

Uso y operación

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.
