Product Description

Z2FS Series Twin Throttle Check Valves (NG10/NG22)

Product Overview: The Z2FS series is a high-performance, sandwich-plate twin throttle check valve designed for regulating the primary flow to hydraulic actuators (cylinders or motors). Featuring a modular “sandwich” design compliant with ISO 4401 standards, this valve mounts directly between the directional valve and the subplate, eliminating extra piping. The dual-adjustment mechanism allows for precise flow regulation in both Ports A and B. The integrated check valve ensures free flow in the opposite direction, making it the premier choice for controlling actuator speeds.

Featured models include: Z2FS10-5-3X/V, Z2FS10-5-33/S2, Z2FS10-2X, and the large-bore Z2FS22-8-3X/S.

Key Technical Advantages:

  • Precise Flow Regulation: Linear adjustment characteristics guarantee stable flow control across various opening stages.

  • Modular Sandwich Design: Saves significant space and simplifies installation; easily stacked under directional valves for compact system integration.

  • Bi-Directional Control: Houses two independent throttle/check valve units in one body, allowing simultaneous or independent speed adjustment for A and B channels.

  • Durable Sealing: Available with “V” (FKM/Viton) seals for compatibility with fire-resistant fluids (e.g., phosphate esters) and high-temperature environments.
