2FRE6‑20 Proportional Flow Control Valve
Product Overview
2FRE6‑20 is a compact 2‑way electro‑hydraulic proportional flow‑control Hydraulic valve, specially designed for stepless, pressure‑compensated flow regulation in space‑limited industrial hydraulic system and automated industrial Machine.
This high‑precision proportional Hydraulic valve adopts NG6 small‑size design, built‑in pressure compensator to maintain stable flow output regardless of load‑pressure changes inside your hydraulic system. It converts analog electrical signals into infinitely‑variable flow, realizing accurate stepless speed adjustment for hydraulic actuators. With low hysteresis, excellent repeatability and fast dynamic response, it delivers reliable flow‑control performance for injection‑molding auxiliary equipment, small hydraulic presses, hydraulic test‑benches and various compact hydraulic‑driven Machine.

Working Principle
2FRE6‑20 proportional flow‑control Hydraulic valve consists of proportional solenoid, metering orifice, pressure compensator and valve‑body assembly. After receiving electrical command signal, the proportional solenoid adjusts the opening of metering orifice. The built‑in pressure compensator keeps constant pressure drop across the orifice, ensuring stable actual flow even when the load pressure of the hydraulic system fluctuates. The optional inductive position sensor feeds real‑time spool‑opening signal back to the amplifier for closed‑loop correction, further improving flow‑control accuracy.
Damaged proportional solenoid, orifice blockage or amplifier failure will cause unstable actuator speed, flow drifting or regulation failure of the Machine. Replacing a qualified 2FRE6‑20 proportional flow control valve can restore accurate stepless flow‑regulation performance of your hydraulic circuit.
