The Sun Hydraulics RVGAMKV (RVGAMKV) is a ventable, pilot-operated, balanced piston relief cartridge designed to function as a normally closed pressure regulating valve. This component is engineered to open and throttle flow to the tank port once the inlet port pressure reaches the pre-set level, effectively regulating pressure. It features a vent port for remote control by other pilot or two-way valves, ensuring precise and smooth operation with minimal noise. The valve can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, though users should account for potential spool leakage in such applications. It's not recommended for load-holding applications due to this leakage characteristic. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the design incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. Notably, this cartridge can be configured with EPDM seals for compatibility with phosphate ester fluid systems, though exposure to petroleum-based substances should be avoided as it can damage the seals. Key specifications include a cavity size of T-17A, series 3 capacity of 60 gpm (240 L/min), and a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with typical response times around 10 ms. The maximum valve leakage at 110 SUS (24 cSt) is rated at 4 in\u00b3/min (65 cc/min). The adjustment mechanism allows up to five clockwise turns to increase settings, with specified installation torques ensuring secure placement and operation.
