The Sun Hydraulics RVGAMCV (Material Number: RVGAMCV) is a ventable, pilot-operated, balanced piston relief cartridge designed for pressure regulation. This normally closed valve opens to the tank port when inlet pressure reaches the set point, smoothly throttling flow to maintain desired pressure levels. It features a vent port that allows remote control by other pilot or 2-way valves, adding versatility in various hydraulic applications. The valve supports maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such configurations. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the design incorporates Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations. This cartridge is not recommended for load-holding applications due to potential spool leakage. It can handle back pressure on the tank port at a 1:1 ratio with the valve setting. For systems using phosphate ester fluids, cartridges with EPDM seals are available but should not be exposed to petroleum-based substances as they may cause damage. The RVGAMCV operates at a maximum pressure of 5000 psi (350 bar) and offers a control pilot flow of 15-20 in\u00b3/min (0.25-0.33 L/min). It has a typical response time of 10 ms and minimal leakage at standard conditions. Installation requires specific torques: valve installation torque between 150-160 lbf ft (203-217 Nm), adjustment screw internal hex size of 5/32 in (4 mm), and locknut torque between 80-90 lbf in (9-10 Nm). With a capacity of up to 60 gpm (240 L/min) and weighing approximately 1.60 lb (0.70 kg), this model is equipped with Viton seal kits for enhanced durability under challenging conditions.
