Product Overview
The NORTHMAN RF-G04-1-E-32-L is a precision-engineered flow control valve belonging to the RF-G04 series of modular hydraulic valves. Manufactured by NORTHMAN, this valve is designed to regulate and meter hydraulic fluid flow within a circuit, providing accurate speed control for actuators and ensuring consistent system performance. As a modular flow control valve, it is engineered for sandwich-style mounting between a directional control valve and a subplate, enabling seamless integration into standardized hydraulic manifolds. The “32” designation indicates a nominal flow capacity of 32 L/min, while the “L” suffix denotes a left-hand adjustment configuration. This valve operates on the principle of variable orifice metering, allowing precise adjustment of flow rate independent of pressure fluctuations, making it an essential component for demanding industrial hydraulic systems requiring reliable velocity control.
