The Sun Hydraulics RVIDCAN (RVIDCAN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain designed for precise pressure regulation. This normally closed valve opens to the tank port when the inlet pressure reaches the preset level, allowing flow throttling to maintain consistent pressure. It features a vent port for remote control and a drain port that ensures insensitivity to back pressure. The valve is known for its accuracy, smooth operation, moderate speed, and low-pressure rise versus flow characteristics. It accepts maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice of the RVIDCAN is protected by a 150-micron stainless steel screen. However, it is not recommended for load-holding applications due to potential spool leakage. The valve setting can be directly influenced by pressure at port 4 at a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). Cartridges with EPDM seals are specifically designed for systems utilizing phosphate ester fluids and should not be exposed to petroleum-based substances. This model incorporates Sun\u2019s floating style construction to minimize internal binding due to installation torque or machining variations. It fits into cavity T-24A and has a capacity of 120 gpm (480 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time around 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is specified as 5 in\u00b3/min (80 cc/min) under a condition of 1000 psi (70 bar).
