REXROTH Z2FS22-31/S2 R900443176

Rexroth Double Throttle Check Valve NG22 Z 2 FS 22-31/S2 Description The Rexroth Z 2 FS 22-31/S2 is a double throttle check valve in a sandwich plate design. It is used to limit the main or pilot flow of one or two actuator ports. This is achieved by throttling the flow in one direction and allowing free flow in the opposite direction. It provides precise control for applications requiring meter-in or meter-out functionality.

What is the primary function of a Z2FS valve in a hydraulic circuit?A Z2FS valve provides flow control for either meter-in (controlling flow into an actuator) or meter-out (controlling flow out of an actuator) applications. It allows fine adjustment of actuator speed. Question? What is the maximum operating pressure for this specific valve model?The maximum operating pressure for the Z2FS 22 series is 315 bar (approximately 4568 PSI), making it suitable for high-pressure industrial systems. Question? Should the O-rings be replaced on this used valve before installation?While the existing O-rings may be in usable condition, for critical applications or to ensure a leak-free installation, it is always best practice to replace the seals with a new, standard NG22 seal kit.
