The Sun Hydraulics RVEAKWN (RVEAKWN) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. This component is engineered to open to the tank port 2 upon reaching the set pressure at inlet port 1, effectively throttling flow to maintain desired pressure levels. A key feature is its vent port 3, which allows for remote control via other pilot or two-way valves. Known for precision and low-pressure rise relative to flow, this valve operates smoothly and quietly with moderate speed. It includes a remote pilot relief on port 3 that enables control below its own setting and can handle maximum pressure at port 2, making it suitable for cross-port relief circuits while considering spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen; however, it is not recommended for load-holding applications due to potential spool leakage. Additionally, back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are advised as exposure to petroleum-based fluids could damage these seals. This design incorporates Sun's floating style construction to minimize internal part binding risks due to excessive installation torque or machining variations of cavity/cartridge. The valve has a cavity T-2A series with a capacity of up to 30 gpm (120 L/min) and operates under maximum pressures of up to 5000 psi (350 bar). It features adjustable settings with five clockwise turns required to increase settings and has specific torque requirements for installation and adjustments. The product weighs approximately .70 lb (.30 kg) and comes with an optional Viton seal kit (990202006).
