The Sun Hydraulics RVEAMUN (RVEAMUN) is a ventable, pilot-operated, balanced piston relief cartridge. This valve is designed to be normally closed, functioning as a pressure regulating device that opens when the inlet port pressure reaches the set threshold, allowing flow to the tank port and thus controlling system pressure. It features a vent port for remote control by other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow, this valve operates smoothly and quietly with moderate speed. The RVEAMUN model can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice includes a 150-micron stainless steel screen for protection. This product is not recommended for load-holding applications due to spool leakage potential. Back pressure on the tank port directly affects the valve setting at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based substances as they can damage the seals. The valve employs Sun's floating style construction to reduce binding risks from excessive torque or machining variations. Key specifications include a cavity T-2A series with a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. The adjustment requires up to five clockwise turns to increase settings, with installation torque ranging from 45 to 50 lbf ft (61 to 68 Nm). The model's weight is approximately 0.70 lb (0.30 kg).
