The Sun Hydraulics RVGAKDV (RVGAKDV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve is typically closed and begins to open when the inlet port pressure reaches the pre-set level, directing flow to the tank port to maintain desired pressure levels. It features a vent port that allows for remote control using other pilot or 2-way valves, offering flexibility in various applications. The RVGAKDV is known for its accuracy, low pressure rise relative to flow, smooth operation, and moderate speed. Additionally, it can handle maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in these scenarios. This model integrates a main stage orifice shielded by a 150-micron stainless steel screen and is not recommended for load-holding applications due to potential spool leakage. Any back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The valve's EPDM seals make it compatible with systems using phosphate ester fluids but unsuitable for petroleum-based fluids. The RVGAKDV features Sun's floating style construction, minimizing risks of internal binding due to installation torque or machining variations. It fits into a T-17A cavity with a series 3 capacity of up to 60 gpm (240 L/min) and can operate at pressures up to 5000 psi (350 bar). The control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with typical response times around 10 milliseconds. The valve allows up to five clockwise turns for adjusting settings and requires specific torques for installation and locknut adjustments. This model weighs approximately 1.60 lb (0.70 kg) and uses Viton seal kits like the 990017006 for maintenance purposes.
