Z2FS6-2-44/2Q (R900481622) Twin Throttle Check Valve Product Description

Core Structural Advantages & Performance Features

1. Integrated Twin Throttle & Check Design

   This valve integrates dual functions of  throttle speed regulation and  one-way check in a compact structure, eliminating the need for separate installation of throttle valves and check valves, effectively saving hydraulic station layout space and reducing pipeline connection complexity. The one-way check function prevents hydraulic oil backflow, avoiding system pressure shock and ensuring stable operation of the hydraulic circuit.
2. High-Precision Flow Regulation

   Adopting precision-machined throttle spool and matching valve core, the Z2FS6 series realizes stepless and fine flow regulation, with stable throttling performance and no obvious flow fluctuation under different pressure conditions. It can accurately control the movement speed of hydraulic actuators (cylinders, motors), improving the operation precision and stability of the whole equipment.
3. Reliable Sealing & Pressure Resistance

   Equipped with high-quality sealing components and optimized valve body structure, the valve has excellent sealing performance and high pressure-bearing capacity, realizing zero leakage under the rated working pressure of the hydraulic system. The valve body is made of high-strength cast iron with high machining precision, which can withstand long-term hydraulic impact and adapt to the continuous working conditions of industrial sites.
4. Standardized Connection & Easy Installation

   Following the international standard hydraulic valve connection specification, the Z2FS6 series adopts a compact cartridge and plate connection structure, with unified installation interface dimensions. It can be directly installed on the hydraulic manifold block or integrated into the hydraulic pipeline, with simple assembly and disassembly. No complex adjustment is needed after installation, which shortens the equipment commissioning cycle.
5. Wide Adaptability & Long Service Life

   The internal components of the valve are made of wear-resistant and corrosion-resistant alloy materials, with low friction coefficient and strong anti-fatigue performance, which can maintain stable working performance under long-term high-frequency operation. It is adaptable to a wide range of hydraulic oil viscosity and working temperature, and can operate normally in the harsh industrial environment with large temperature changes and slight oil pollution.
