This product is a high-precision hydraulic one-way flow control valve. It is widely used in construction machinery, automated production lines, lifting equipment and various hydraulic transmission systems. It can control single-direction oil flow speed, stabilize running velocity of actuators, and ensure smooth and steady mechanical movement.

Working medium: Mineral-based hydraulic oilOil cleanliness standard: ISO 4406Rated working pressure: 21 MPaMaximum bearing pressure: 25 MPaApplicable fluid viscosity: 15~68 mm²/sOperating temperature range: -20℃ ~ +80℃Regulation mode: Manual stepless flow adjustmentFlow control feature: One-way speed regulationInternal leakage: Low leakage volumeInstallation form: Standard thread connectionService feature: Stable operation for long-term frequent use

Precision internal matching structure achieves accurate flow regulation.Wear-resistant core components extend overall service life effectively.Optimized flow channel design reduces hydraulic pressure loss.Reliable one-way locking function prevents oil flow backflow.High-quality sealing components avoid external oil seepage.Compact and lightweight structure saves installation space.Strong vibration resistance, suitable for various harsh working environments.Simple adjustment operation, easy on-site speed setting and maintenance.

Clean oil ports and internal oil passages to remove dirt and impurities before installation.Install the valve according to marked flow direction, tighten threads with standard torque, avoid over tightening damage.Connect hydraulic pipelines firmly and check interface sealing condition.Confirm installation direction is correct to guarantee normal one-way speed control effect.

Complete installation and conduct no-load test run.Slowly inject hydraulic oil and check all joints for oil leakage.Adjust flow rate gently to set ideal working speed as actual demand.Keep hydraulic oil clean in daily use, replace filter elements regularly to prevent blockage.Do not use under overpressure working condition.Release system pressure completely before equipment maintenance.

Regularly check threaded joints and sealing positions for oil leakage, replace aging seals timely.Periodically inspect flow regulation stability and calibrate speed if deviation occurs.Keep valve outer surface clean to avoid dust accumulation affecting use.Unauthorized disassembly is prohibited to prevent damage to internal precision parts.

All installation, adjustment and maintenance work must be carried out after equipment shutdown, power cut and full hydraulic pressure relief, to avoid injury caused by high-pressure hydraulic oil.Operate strictly in accordance with safety operation rules.Keep the product away from high temperature heat sources and corrosive substances.Stop operation immediately once speed instability, abnormal noise and leakage happen, and arrange professional inspection and repair in time.
