The Rexroth 2FRM6B36-31/1.5 QMV is a 2-way flow control valve of sandwich plate design, engineered to maintain a constant flow rate regardless of pressure and temperature fluctuations. This particular model, size 6, features a lockable rotary knob with a scale for precise and repeatable adjustments. It is designed for meter-in flow control and includes an integrated check valve, allowing for free flow in the return direction. Its robust construction and FKM seals make it suitable for a wide range of hydraulic fluids and applications where accurate speed control of actuators is required.
