The Rexroth HSZ 10 A426-1X/ALJ4-BLJ4M00 is a pilot-operated sequence valve designed for sandwich plate mounting according to ISO 4401 standards. This valve is engineered to ensure that a secondary hydraulic circuit is activated only after a preset pressure level is reached in the primary circuit. It features an integrated check valve that allows for free return flow from the secondary to the primary circuit. Renowned for its robust construction and precision, this valve provides reliable and accurate pressure-dependent sequence control, making it a crucial component in complex industrial hydraulic systems for automating machine cycles.
