The Sun Hydraulics RVEAQVN (RVEAQVN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when the inlet pressure reaches the set point, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or 2-way valves. Known for its accuracy and smooth operation, this valve exhibits a low-pressure rise versus flow and operates quietly with moderate speed. Engineered to accept maximum pressure at port 2, the RVEAQVN is suitable for cross port relief circuits but should be used with consideration of spool leakage. It is not recommended for load holding applications due to potential leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. The valve's construction incorporates Sun\u2019s floating style design to reduce internal binding risks caused by excessive installation torque or machining variations. This model accommodates systems using phosphate ester fluids with EPDM seals while petroleum-based fluids can damage these seals. With a capacity of 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar), it offers reliable performance in demanding environments. The factory pressure settings are established at 4 gpm (15 L/min), and it exhibits a typical response time of 10 ms. Installation requires specific torque values: the valve hex size is 1-1/8 inches (28.6 mm) with an installation torque of 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), and the locknut needs tightening at 80-90 lbf in (9-10 Nm). The model weighs .70 lb (.30 kg) and includes Viton seal options under part number 990202006 for enhanced durability in various applications.
