The Sun Hydraulics RVCACGN (RVCACGN) 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 setpoint, effectively throttling flow to maintain desired pressure levels. It features a vent port that enables remote control via other pilot or two-way valves. Known for its accuracy and moderate response speed, this valve operates smoothly and quietly with minimal pressure rise relative to flow. It is crucial to note that while it can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, though it's not recommended for load-holding applications due to potential leakage. The valve's backpressure on the tank port directly adds to the setting at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are available; however, exposure to petroleum-based substances could damage these seals. The design incorporates Sun's floating style construction to minimize binding risks from excessive installation torque or machining variations. Key specifications include a cavity type T-11A with a Series 1 capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow between 7-10 in\u00b3/min (0.11-0.16 L/min). The typical response time is approximately 10 ms, with maximum valve leakage at specified conditions being 2 in\u00b3/min (30 cc/min). Installation requires specific torque values and hex sizes for adjustments and locknuts, ensuring secure setup and operation.
