Product Overview
The Rexroth MK 25 G14/V (Material Number R900423330) is a modular throttle check valve designed for precise flow control in industrial hydraulic systems. As part of the Rexroth MK series, this valve is engineered to regulate actuator speed by restricting flow in one direction while permitting unrestricted reverse flow through an integrated check function. The G14 designation indicates a nominal flow size of NG14 with a G1/2 threaded connection interface, and the V suffix denotes a Viton (FKM) seal compound for enhanced fluid compatibility and elevated temperature resistance. This sandwich-style modular valve mounts directly between standard ISO 4401 / DIN 24340 interface plates, enabling compact system integration without additional piping. It serves as a critical metering component in circuits requiring accurate velocity control of cylinders and motors, offering dependable performance in demanding industrial environments.
