Product Overview
The Rexroth MK 6 G1X/V (Material Number R900423340) is a modular throttle check valve designed for precise flow control within industrial hydraulic systems. As part of Rexroth’s proven modular valve program, this unit combines a manually adjustable throttle with an integrated check valve function, allowing free flow in one direction and controlled, restricted flow in the opposite direction. The valve is engineered for sandwich (modular) mounting, enabling direct integration into standardized valve stacks without additional piping. Its robust construction and precision metering characteristics make it a reliable choice for regulating actuator speeds and balancing flow in demanding hydraulic circuits.
