Double throttle check valves – sandwich module

Z2FS

Double throttle/check sandwich type valves

Flow control valves, Model Z2FS, are double throttle/check sandwich type valves. They restrict flow to or from actuator ports (A & B) of a directional valve. Two throttle/check valves, symmetrically arranged in the housing, restrict flow with adjustable throttles in one direction while providing free flow in the opposite direction.
