The Sun Hydraulics RVIDLCV (RVIDLCV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve is normally closed and activates by opening to tank port 2 when the inlet port 1 pressure reaches the pre-set level, thereby throttling flow to maintain the desired pressure. It features a vent port 3 for remote control capabilities and a drain port 4 that ensures insensitivity to back pressure. This model is characterized by its accuracy, low pressure rise versus flow, smooth operation, quiet performance, and moderate speed. The RVIDLCV can handle maximum pressures at port 2 and is suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. The main stage orifice of this valve is protected by a 150-micron stainless steel screen, though it is not recommended for load-holding applications due to potential leakage. The valve setting can be directly influenced by the pressure at port 4 at a 1:1 ratio, with a maximum limit of 5000 psi (350 bar). Cartridges with EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based substances. The valve incorporates Sun's floating style construction to reduce risks of internal binding from excessive torque or machining variations. Additional specifications include a cavity T-24A series with a capacity of up to 120 gpm (480 L/min), factory pressure settings established at 4 gpm (15 L/min), and an operating pressure ceiling of 5000 psi (350 bar). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), while typical response time is approximately 10 ms. Maximum valve leakage at specified conditions is limited to 5 in\u00b3/min (80 cc/min). This model weighs approximately 3.10 lb (1.40 kg) and includes Viton seal kits under part number 990024006 for maintenance needs.
