The Sun Hydraulics RVEDCEV (RVEDCEV) is a ventable, pilot-operated, balanced piston relief cartridge designed with an external drain for effective pressure regulation. This normally closed valve begins to open at the inlet port 1 when the pressure surpasses the set threshold, directing flow to tank port 2 to manage pressure levels. It features a vent port 3 for remote control and a drain port 4, making it insensitive to back pressure. The valve is recognized for its precision, low-pressure rise versus flow, smooth operation, and moderate speed. It accepts maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. This product is not recommended for load-holding applications due to potential spool leakage. The pressure at port 4 can add directly to the valve setting at a 1:1 ratio but should not exceed 5000 psi (350 bar). Cartridges with EPDM seals are compatible with phosphate ester fluids but are vulnerable to damage from petroleum-based substances. The W and Y controls allow full-range adjustment unless a special setting limits the maximum adjustment range. Its construction minimizes internal part binding risks due to installation torque or machining variations. The RVEDCEV fits into Cavity T-22A Series-2 with a capacity of up to 30 gpm (120 L/min) and operates under pressures as high as 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), with a typical response time of about 10 milliseconds. Maximum valve leakage stands at approximately 3 in\u00b3/min under specified conditions. Installation specifics include a valve hex size of 1-1/8 inches and an installation torque between 45-50 lbf ft (61-68 Nm).
