The Sun Hydraulics RVIDKAN (Material Number: RVIDKAN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed as a normally closed pressure regulating valve. It opens to the tank port when the inlet pressure reaches the set level, regulating flow and maintaining pressure. This model features a vent port for remote control and a drain port that makes it insensitive to back pressure. It is known for its accuracy, low-pressure rise versus flow, smooth operation, quiet performance, and moderate speed. The valve can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is protected by a 150-micron stainless steel screen. It is important to note that this valve is not suitable for load-holding applications due to spool leakage. The pressure at port 4 adds directly to the valve setting at a 1:1 ratio but should not exceed 5000 psi (350 bar). Cartridges with EPDM seals are compatible with phosphate ester fluids but may be damaged by petroleum-based fluids. The RVIDKAN incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or cavity machining variations. It fits into Cavity T-24A and has a capacity of up to 120 gpm (480 L/min). The maximum operating pressure is 5000 psi (350 bar), with control pilot flow ranging from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min) and typical response time of about 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is approximately 5 in\u00b3/min at 1000 psi (80 cc/min at 70 bar). Adjustments are made via an internal hex screw requiring specific torque settings for installation and locknut adjustments. The model weighs approximately 3.10 lb (1.40 kg).
