2FRM Series 2-Way Flow Control Valves (Pressure & Temp. Compensated)

Product Overview: The 2FRM series is a high-precision solution for regulating the speed of hydraulic actuators (cylinders or motors). As a premier 2-way flow control valve, it integrates a pressure compensator to ensure that the flow rate remains constant regardless of system pressure fluctuations. Additionally, the series features temperature compensation, significantly reducing flow drift caused by oil viscosity changes as temperatures rise. From precision machine tool feed controls to heavy-duty synchronized machinery, the 2FRM series delivers exceptional linear regulation.

Featured models: 2FRM10-21B/25L, 2FRM10-21B/50L, 2FRM10-21B/35L, 2FRM16-22/160L, and 2FRM6B/76-20B/10QM.

Key Technical Advantages:

• Dual Compensation Mechanism: Built-in pressure compensation and precision orifice design effectively counteract flow drift caused by pressure and temperature variations.

• High Regulation Accuracy: The adjustment handwheel features a scale and optional locking mechanism to prevent setting shifts in high-vibration environments.

• Comprehensive Range: Available in Size 6 (NG6), Size 10 (NG10), and Size 16 (NG16), covering flow rates from micro-metering to 160 L/min.

• Optional Reverse Free Flow: Can be equipped with an integrated check valve for controlled flow in one direction and free flow in the reverse.

• Smooth Low-Speed Performance: Extremely low minimum stable flow rate, ideal for applications requiring ultra-slow, steady movement.
