Product Overview
The Rexroth MSR 30 KE-05-1X (Material Number R900344919) is a pilot-operated sequence valve from the proven MSR series, designed for precise pressure-dependent control of actuator sequencing in industrial hydraulic systems. As a pressure control valve, it maintains a set secondary pressure and releases flow to a downstream circuit only once the preset pressure threshold is reached, enabling reliable load-holding and ordered motion of multiple actuators. The KE-05-1X designation indicates a size 30 valve with a specific adjustment and connection variant, making it a direct-fit replacement for OEM installations requiring exact functional and dimensional interchangeability.
