The Sun Hydraulics RVEDKYV (RVEDKYV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when inlet pressure reaches the set threshold, throttling flow to maintain desired pressure levels. It features a vent port for remote control and an external drain port, making it insensitive to back pressure. The valve is noted for its accuracy, low-pressure rise versus flow, smooth operation, and moderate response speed. It can withstand maximum pressure at port 2 and is suitable for cross-port relief circuits with considerations for spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. Notably, this model is not recommended for load-holding applications due to potential spool leakage. Pressure at the drain port directly affects the valve setting at a 1:1 ratio but should not exceed 5000 psi (350 bar). Cartridges equipped with EPDM seals are compatible with phosphate ester fluids but can be damaged by petroleum-based substances. Adjustments are made using W or Y controls, which can be specified with or without a special setting; without it, the valve adjusts throughout its range. The Sun floating style construction minimizes internal part binding risks due to installation torque or machining variations. Key specifications include a cavity size of T-22A Series 2 and a capacity of 30 gpm (120 L/min). Factory settings are established at 4 gpm (15 L/min), with maximum operating pressure reaching 5000 psi (350 bar) and control pilot flow between 10-15 in\u00b3/min (0.16-0.25 L/min). The typical response time is approximately 10 ms, and maximum leakage at standard conditions is 3 in\u00b3/min (50 cc/min).
