Product Overview
The Rexroth MSR 25 KE05-1X (Material Number R900344778) is a pilot-operated sequence valve designed for precise pressure-dependent control of actuator sequencing in industrial hydraulic systems. As a member of the Rexroth MSR series, this valve ensures that a secondary circuit is only pressurized once a predetermined pressure level has been reached in the primary circuit, enabling reliable, repeatable load sequencing without external electrical control. The valve features a robust housing, an adjustable pressure setting via a threaded adjustment element, and an integrated check function for free return flow. Its design is optimized for high-pressure industrial applications where accurate pressure control and dependable switching behavior are essential for safe and efficient machine operation.
