Product Description
Z2FS Series Double Throttle Check Sandwich Valves
Product Overview: The Z2FS series is a classic sandwich plate double throttle check valve designed for the flow regulation of actuators (cylinders or motors). Its modular sandwich design allows it to be mounted directly between the directional valve and the subplate, eliminating additional piping and significantly streamlining hydraulic system integration. Featuring two independent adjustment screws, users can precisely fine-tune the flow in both ports A and B, ensuring smooth and synchronized actuator movements.
Featured models: Z2FS10-5-3X/V, Z2FS6-32, Z2FS16-8-3X/S, Z2FS16-30B/S, and the complete Z2FS10-5-33 range.
Key Technical Advantages:
Sandwich Plate Design: Minimizes space requirements and reduces potential leakage points, aligning with modern integrated hydraulic station trends.
Independent Dual Adjustment: The throttle valves for channels A and B are entirely independent, allowing for both meter-in or meter-out control (depending on installation orientation).
Precise Regulation: Utilizes fine-thread adjustment rods to ensure high linearity and resolution across a broad flow spectrum.
Thermal & Chemical Resistance: Models with the /V suffix (e.g., Z2FS10-5-3X/V) are equipped with FKM (Viton) seals, providing superior resistance to chemical corrosion and high temperatures.
