Proportional Flow Control Valve 2FRE6B-22/3QK4MV Hydraulic Valve for Industrial Machinery

This 2FRE6B-22/3QK4MV is a two-way proportional flow control hydraulic valve. It consists of proportional solenoid, throttle spool and pressure compensator. It converts electrical input signal into mechanical displacement of spool to adjust flow area, so as to regulate hydraulic flow and control the movement speed of hydraulic actuators.
This valve can maintain stable flow output independent of load pressure changes. Precision spool machining reduces flow deviation, delivers consistent regulation performance and keeps low noise during continuous working cycles.
The 2FRE6 series covers multiple flow specifications. It adopts proportional electric control mode and can be integrated into various open hydraulic circuits. It serves as precision flow regulation component for different industrial hydraulic systems.
