The Sun Hydraulics RVEALVV (RVEALVV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows remote control through other pilot or two-way valves, enhancing its versatility in various applications. Known for its accuracy and smooth operation, this valve is moderately fast with low pressure rise versus flow characteristics. It is suitable for use in cross-port relief circuits, although spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability under demanding conditions. However, it is not recommended for load-holding applications due to potential spool leakage. The valve's setting can be influenced by back pressure at the tank port at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are available; caution should be taken to avoid exposure to petroleum-based substances as they can damage these seals. Incorporating Sun's floating style construction minimizes risks of internal binding due to installation torque or machining variations. The RVEALVV model operates with a maximum flow capacity of 30 gpm (120 L/min) and withstands pressures up to 5000 psi (350 bar). Its response time is typically around 10 milliseconds with minimal valve leakage under specified conditions. The adjustment mechanism allows fine-tuning with up to five full clockwise turns needed to increase settings. Installation requires specific torque values for both the valve and locknut components, ensuring secure and proper assembly within hydraulic systems.
