This is a precision hydraulic flow control valve, mainly used to adjust and stabilize oil flow rate in hydraulic circuits. It is widely applied in construction machinery, industrial equipment, automation hydraulic systems and mechanical transmission devices, to control moving speed of actuators and ensure smooth and steady equipment operation.

Working medium: Standard mineral hydraulic oilFluid cleanliness: Comply with ISO 4406 standardRated working pressure: 21 MPaMax allowable pressure: 25 MPaApplicable oil viscosity: 15~68 mm²/sOperating temperature: -20℃ ~ +80℃Flow adjusting range: Stable stepless flow regulationInternal leakage: Low leakageInstallation type: Standard thread mountingWorking feature: Bidirectional or unidirectional flow control available

Precision internal structure ensures accurate flow regulation and stable speed control. Wear-resistant core parts extend service life for long-time repeated use. Compact body design saves installation space and facilitates pipeline layout. Fine adjustment structure enables easy on-site speed setting. Good sealing performance effectively avoids external oil leakage. Strong anti-vibration performance keeps stable working state under complex working conditions. Simple structure with low failure rate and easy daily maintenance.

Clean thread ports and internal oil passages thoroughly before installation to clear all dirt and impurities. Screw the valve into the designated mounting position and fasten with proper torque, avoid over tightening to prevent thread damage. Install strictly according to flow direction mark to guarantee correct oil circulation direction. Recheck assembly condition to ensure firm connection after installation finished.

Complete installation and connect hydraulic pipelines properly, then carry out no-load test. Slowly feed hydraulic oil and check all joints for oil leakage. Adjust flow volume gradually according to actual speed demand to reach ideal operating speed. Keep hydraulic oil clean during daily use, replace filter elements regularly to prevent internal blockage. Do not operate beyond rated pressure range. Release system pressure fully before equipment stop and maintenance work.

Regularly check valve body and connecting threads for oil seepage, replace worn seals timely. Periodically inspect flow control stability and make fine adjustment if speed deviation occurs. Keep outer surface clean to prevent dust and oil sludge accumulation. Unauthorized disassembly is forbidden, which may damage internal precision matching parts and affect regulation accuracy.

All installation, adjustment and maintenance work must be done after equipment shutdown, power cut and full hydraulic pressure relief, to prevent personal injury caused by high-pressure fluid. Operate strictly in accordance with safety operation rules. Keep the valve away from high temperature and corrosive medium. Stop operation immediately once abnormal noise, speed instability and leakage happen, and arrange professional inspection and repair in time.
