Q1: What is the main purpose of this valve?
A: It is a manually adjustable throttle valve designed to precisely control the speed of a hydraulic actuator (like a cylinder) in one direction. It meters the flow from Port 1 to Port 2. The integrated check valve allows for unrestricted return flow from Port 2 to Port 1.
Q2: What does the model suffix "/S2" signify?
A: The "/S2" suffix typically indicates a specific production revision, a particular batch of seal material, or a minor design variant within the standard Z2FS16-8-3X product line. The core specifications (size, pressure, function) remain the same as the base model. For exact details on what distinguishes the "/S2" variant, it is essential to consult the official parts documentation or datasheet.
Q3: What is the valve's pressure rating?
A: The valve is rated for a maximum operating pressure of 315 bar.
