The Sun Hydraulics RVEDWWV (RVEDWWV) is a ventable, pilot-operated, balanced piston relief cartridge designed to function as a normally closed pressure regulating valve. This versatile component operates by opening the valve to tank port 2 when the inlet port 1 pressure reaches the set threshold, effectively throttling flow to maintain regulated pressure. It features a vent port 3 for remote control and a drain port 4 that ensures insensitivity to back pressure. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. Ideal for applications requiring maximum pressure at port 2, the RVEDWWV is suitable for cross-port relief circuits but not recommended for load-holding uses due to spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. Pressure at port 4 directly adds to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). Cartridges with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The RVEDWWV incorporates Sun's floating style construction, minimizing internal binding risks from excessive installation torque or machining variations. It fits into Cavity T-22A with a series capacity of up to 30 gpm (120 L/min) and operates at a maximum pressure of 5000 psi (350 bar). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), with typical response times around 10 ms. The valve features adjustable settings through clockwise turns and includes specific torque requirements for installation and locknut adjustments. Its compact design weighs approximately .70 lb (0.30 kg), making it an efficient choice for various hydraulic applications requiring reliable pressure regulation.
