The Rexroth SL 10 PA2-4X/ is a high-performance, pilot-operated check valve designed for reliable, leak-free blocking of an actuator port, even during extended periods of standstill. As a sandwich plate valve of size 10, it integrates seamlessly into vertical stacking systems with an ISO 4401 porting pattern. This model provides a check function in port A, allowing free flow from A2 to A1 while securely blocking flow in the opposite direction. By applying sufficient pilot pressure, the check valve can be opened to permit reverse flow. Its robust construction and proven design make it an ideal choice for demanding hydraulic applications requiring precise load holding and safety functions.
