Rexroth Z2FS 10 Hydraulic Throttle Check Valve

Description

This is a Rexroth Z2FS 10-5-34/V hydraulic throttle check valve, identified by material number R900517812. It is a sandwich plate valve of nominal size 10 (NG10), designed for mounting in vertical stacking systems. The primary function is to control the flow rate (throttling) in one direction and allow free flow in the opposite direction. This model is ideal for meter-in or meter-out applications, providing precise control over actuator speed.

FAQ

What is the function of the “/V” suffix in the type number Z2FS 10-5-34/V?

The “/V” indicates that the valve is fitted with Viton (FKM) seals. These seals offer superior resistance to high temperatures and a broader range of chemicals and hydraulic fluids compared to standard NBR seals.

What is the nominal size (NG) of this valve and what does it mean?

The nominal size is NG10, which corresponds to the CETOP 5 mounting pattern standard. This ensures interchangeability with other NG10 valves and subplates from various manufacturers, defining the port locations and mounting bolt pattern.

Can this valve be used for meter-in or meter-out control?

Yes, absolutely. By correctly orienting the sandwich plate during installation, it can be configured to control flow into the actuator (meter-in) or out of the actuator (meter-out), allowing for precise speed control.
