Product Overview
The Rexroth MK 20 G14/V (Material Number R900423328) is a modular throttle check valve from the proven Rexroth MK series, engineered for precise flow control and load-holding functions within industrial hydraulic systems. As a sandwich-style modular valve, it mounts directly between a directional control valve and its subplate in accordance with ISO 4401 / DIN 24340 interface standards, eliminating the need for additional piping. The valve combines a manually adjustable throttle function for regulating actuator speed in one direction with a leak-free seated check function that permits unrestricted reverse flow. This dual-function design makes the MK 20 G14/V an essential component for meter-in and meter-out speed control, load holding, and synchronized motion applications in demanding hydraulic circuits.
