2FRM Pressure Compensated Speed Control Valve

Product Overview

2FRM Pressure Compensated Speed Control Valve is a precision‑grade Hydraulic valve. It is installed in the hydraulic system to adjust oil flow and maintain constant actuator speed, even under varying load conditions of the Machine. With built‑in pressure compensation unit and integrated check valve, it provides throttling speed regulation in forward direction and free reverse oil passage. Damaged or improperly calibrated Hydraulic valve will result in unstable operating speed, motion jitter and speed deviation of cylinders and motors. This unit follows international mounting standards, ideal for new‑machine assembly as well as maintenance and retrofit of the hydraulic system.

Technical Specifications

- Model: 2FRM Pressure Compensated Speed Control Valve

- Valve category: Two‑way pressure‑compensated flow control Hydraulic valve

- Nominal size: 5, 10, 16

- Maximum working pressure: 31.5 MPa

- Flow range: 0.2‑160 L/min (varies by sub‑model)

- Working fluid: Anti‑wear hydraulic mineral oil

- Operating temperature: ‑20℃ ~ +80℃

- Mounting: Standard ISO plate‑mount interface

- Adjustment: Knob with scale and locking device

- Core function: Forward flow throttling; free reverse flow through internal check valve

Working Principle

When oil flows forward inside the hydraulic system, fluid passes through the throttle opening. Rotating the adjustment knob changes orifice area to set target flow rate. The built‑in pressure compensator spool automatically shifts to keep constant pressure difference across the throttle. In this way, flow output remains stable regardless of load fluctuation from the Machine. During reverse flow, the internal check valve opens fully, so oil returns without throttling resistance. When bidirectional speed control is necessary, matching rectifier sandwich plate can be equipped.

Core Advantages

1. Professional pressure‑compensated structure, flow output is little affected by load changes of the Machine.

2. High‑precision throttle edge, reduces flow drift caused by temperature change of hydraulic system oil.

3. Lockable adjustment knob, preserves preset parameters and avoids accidental mis‑operation on site.

4. Standard mounting dimension, convenient replacement for original Hydraulic valve without extra machining.

5. Combined throttle and check‑valve structure, simplifies piping layout and supports long‑term cyclic operation.

6. Effectively solves typical equipment defects: unstable speed, jerky movement, inconsistent actuator running speed.

Application Scope

This Hydraulic valve is widely adopted on various industrial Machine, including machine tools, hydraulic presses, injection‑molding equipment, metallurgical machinery and test benches. As a vital flow‑regulating component of the hydraulic system, it accurately controls cylinder travel speed and hydraulic motor rotating speed for industrial production facilities.
