The Sun Hydraulics RVEACUV (RVEACUV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open when the inlet port pressure reaches the predetermined setting, allowing flow to the tank port and thus regulating system pressure. It features a vent port that facilitates remote control via other pilot or two-way valves. Known for its accuracy and smooth operation, this valve exhibits a low-pressure rise relative to flow and operates quietly with moderate speed. The valve can be controlled below its own setting using a remote pilot relief on the vent port. It is capable of handling maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and performance stability. It\u2019s important to note that this valve is not recommended for load-holding applications due to potential spool leakage. Back pressure on the tank port directly affects the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for use with phosphate ester fluids only; exposure to petroleum-based substances can damage these seals. Incorporating Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. The RVEACUV has a capacity of 30 gpm (120 L/min), with factory pressure settings established at 4 gpm (15 L/min) and a maximum operating pressure of 5000 psi (350 bar). Its response time is typically around 10 ms, with minimal leakage under specified conditions. The valve includes adjustable settings via an internal hex screw and locknut, ensuring flexibility and ease of use in various hydraulic applications.
