The Sun Hydraulics RVCACBV (RVCACBV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve is normally closed and begins to open when the inlet port 1 pressure reaches the pre-set level, allowing flow to the tank port 2 to maintain the desired pressure. It features a vent port 3 for remote control via other pilot or two-way valves, ensuring accuracy with low pressure rise against flow. The valve's construction is smooth and quiet with moderate response speed, typically around 10 milliseconds. It accepts maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is protected by a durable 150-micron stainless steel screen. Notably, this cartridge is not recommended for load-holding applications due to potential spool leakage. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges configured with EPDM seals are appropriate; exposure to petroleum-based substances can damage these seals. Incorporating Sun's floating style construction minimizes internal part binding risks from excessive installation torque or cavity/cartridge machining variations. The valve has a capacity of up to 15 gpm (60 L/min) and can operate under pressures up to 5000 psi (350 bar). Control pilot flow ranges between 7-10 in\u00b3/min (0.11-0.16 L/min), with maximum valve leakage at approximately 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). Adjustment involves up to five clockwise turns to increase settings, utilizing an internal hex screw size of 5/32 inch (4 mm). The valve weighs approximately .40 lb (0.20 kg) and requires an installation torque of between 30-35 lbf ft (41-47 Nm).
