For supply or discharge throttling
The valve type Z2FS is a throttle check valve in sandwich plate design. It is used for the flow limitation of one or two actuator ports. Two symmetrically arranged throttle check valves limit flows (by adjustable throttle spools) in one direction and allow free return flow in the opposite direction.
Features of the sea water resistant version
When compared to the standard version the following modifications have been carried out:
The external metal components, housing and plug, have been zinc galvanised or given an anti-protection protection.
The adjustment is protected against corrosion by a cap.
Sea water resistance is identified by the code „J“ in the ordering code.
