ZNS Series Flow Control Valves

Series ZNS sandwich flow control valves controls the actuator movement at overrunning loads. The return flow from the actuator is piloted and controlled by the inlet flow to the actuator, ensuring a cavitation-free lowering of the load. Series ZNS features controlled movement loads, load holding via leak-free poppet valve, and secondary relief protection for the actuator.
