Product Overview
The Rexroth MK 8 G14/V (Material No. R900423343) is a modular throttle check valve designed for precise flow control within industrial hydraulic systems. As part of Rexroth’s proven MK series, this valve functions as a sandwich plate component that meters flow in one direction while allowing unrestricted return flow in the opposite direction. The “G14” designation indicates a nominal flow adjustment range, and the “V” suffix denotes the sealing material (FKM/Viton) for enhanced chemical and thermal resistance. This valve is engineered for integration into modular hydraulic manifolds, providing reliable speed control of actuators and precise flow regulation in demanding industrial circuits.
