Purchase now: Winner RP-10 A 20W Relief Valve
Purchase now: Atlantech Drives provides you the Winner Hydraulics RP-10 A 20W, a high-performance Pilot Operated Relief Valve. This screw-in cartridge valve is designed to limit the maximum pressure in a hydraulic circuit, protecting the pump and actuators from over-pressurization. Unlike direct-acting valves, this pilot-operated model offers exceptional stability and low pressure rise (hysteresis) even at high flow rates, making it the ideal choice for continuous duty applications in mobile and industrial hydraulics.
Technical Specifications and Cavity Details
The RP-10 A 20W fits into a standard C-10-2 Cavity (Industry standard Size 10, 2-way). It operates by blocking flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the pilot poppet off its seat. The «20W» suffix indicates the specific pressure adjustment range (typically calibrated for medium-to-high pressure systems, check specific spring range in datasheet, usually up to 210-350 bar). It features an internal Damping Chamber to prevent oscillation and chatter, ensuring quiet operation.

Expert Tips: Setting the Pressure
Avoid system shock. Expert Tip: When installing the RP-10 A 20W, always start with the adjustment screw backed out (lowest pressure setting). Start the pump and slowly turn the screw clockwise to increase the pressure until you reach the desired system cracking pressure. Pilot-operated valves are sensitive; a small turn can result in a significant pressure jump. Always use a calibrated gauge at Port 1 during setup.
Frequently Asked Questions (FAQs)
Q: What is the difference between Pilot and Direct Acting?
A: Pilot valves (like this RP-10) have a flatter pressure vs. flow curve. They maintain the set pressure more accurately as flow increases, whereas direct-acting valves tend to let pressure rise significantly with flow.
Q: Can it be used as a safety valve?
A: Yes, it is primarily designed as a main system relief valve to prevent component failure due to pressure spikes.
