The Sun Hydraulics RVEAMRV (RVEAMRV) 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, throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control through other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. The RVEAMRV can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. However, this valve is not recommended for load-holding applications due to potential spool leakage. The RVEAMRV incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It can handle back pressure on the tank port directly added to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; however, exposure to petroleum-based fluids will damage these seals. The valve has a capacity of 30 gpm (120 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It features an adjustment range facilitated by five clockwise turns and requires specific torque settings for installation and adjustment components. The model weighs .70 lb (.30 kg) and includes options like Viton seal kits for enhanced performance in various hydraulic systems.
