The Sun Hydraulics RVGAKAN (RVGAKAN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet port pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. It features a vent port for remote control by other pilot or 2-way valves, offering accurate performance with low pressure rise versus flow. The valve is smooth and quiet in operation and provides moderate response speed. It accepts maximum pressure at port 2, making it suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, while backpressure on the tank port directly adds to the valve setting at a 1:1 ratio. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. The RVGAKAN is not recommended for load holding applications due to potential spool leakage. This model has a cavity T-17A and Series 3 capacity of up to 60 gpm (240 L/min), with factory pressure settings established at 4 gpm (15 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with control pilot flow between 15 \u2013 20 in\u00b3/min (0.25 \u2013 0.33 L/min) and typical response time of around 10 ms. Maximum valve leakage at specified conditions is limited to 4 in\u00b3/min (65 cc/min). Installation requires specific torque values: valve installation torque is between 150 \u2013 160 lbf ft (203 \u2013 217 Nm), with adjustment screw internal hex size of ^5\u204432 inch and locknut torque between 80 \u2013 90 lbf in (9 \u201310 Nm). The model weighs approximately 1.60 lb (0.70 kg) and uses Viton seal kits available under part number: 990017006.
