FD Check Valves

The Bosch Rexroth FD Check Valves is a leakage-free, pilot-operated check valve designed for use in mobile and stationary hydraulic systems. Its main function is to reliably control the returning flow from an actuator, such as a cylinder, in relation to the flow being directed into the opposite side The valve operates by using pilot pressure from the inlet side to unseat a main check element, allowing controlled reverse flow while preventing unwanted movement or sudden pressure drops. Available in cartridge, sub-plate, and flanged versions, these valves are essential for safety and holding loads by ensuring fluid only flows in the intended direction until pilot pressure permits unblocking. They are robustly designed for high-performance applications, handling maximum flows up to 560 l/min and pressures up to 350 bar.
