Product Overview
The Rexroth SL 30 PA1-42 (Material No. R900587560) is a pilot operated check valve from the proven Rexroth SL series, designed for leak-free load holding and controlled flow release in industrial hydraulic systems. As a modular sandwich-style valve, it is engineered for direct mounting between a directional control valve and a subplate, conforming to ISO 4401 / DIN 24340 interface standards. The valve permits free flow in one direction and blocks reverse flow until a sufficient pilot pressure signal is applied to unseat the poppet, enabling controlled lowering of loads, prevention of drift, and safe isolation of actuators. Its robust poppet-and-seat design delivers reliable sealing performance with minimal internal leakage, making it a critical safety and load-holding component in demanding hydraulic circuits.
