The Sun Hydraulics RPICMBV (RPICMBV) is a pilot-operated, balanced-piston relief cartridge designed for pressure regulation in hydraulic systems. This valve is normally closed and begins to open to the tank port when the inlet pressure reaches the valve setting, thereby throttling flow to maintain desired pressure levels. Known for its accuracy, smooth and quiet operation, and moderate response speed, it is suitable for applications involving cross port relief circuits. However, users should consider spool leakage when using it in such circuits. The main stage orifice of the valve is protected by a 150-micron stainless steel screen, enhancing its durability and reliability. It is important to note that this valve is not recommended for load-holding applications due to potential spool leakage. The back pressure at tank port 2 directly affects the valve setting at a 1:1 ratio. The RPICMBV cartridge features interchangeable components with other 2-port relief cartridges of similar size and flow path, except for pilot reliefs. It can be configured with EPDM seals for compatibility with phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. Corrosion-resistant options are available with stainless steel or zinc-nickel plated external components. The Sun floating style construction minimizes internal part binding due to installation torque or machining variations. With a cavity size of T-16A and series 3 capacity allowing up to 100 gpm (380 L/min), this valve operates under a maximum pressure of 5000 psi (350 bar). It has a typical response time of 10 ms and maximum valve leakage under specified conditions of 4 in\u00b3/min (65 cc/min). Installation requires specific torque settings, and adjustments can be made using an internal hex adjustment screw. The model weighs approximately 1.20 lb (0.55 kg) and uses Viton seal kits for efficient performance in various environments.
