The Rexroth SL20 PA3-43 (Part Number: R983040160) is a highly reliable pilot-operated check valve designed for demanding industrial hydraulic applications. This valve is engineered to allow free flow in one direction while providing leak-free closure in the opposite direction. The blocked flow can be unblocked by applying a pilot pressure, making it an ideal component for holding loads in position, clamping circuits, or isolating hydraulic systems. Manufactured in India to Bosch Rexroth’s stringent quality standards, this model features standard A and B ports with integrated mounting holes for secure and straightforward installation.
