The Sun Hydraulics RVGAMGV (Material Number: RVGAMGV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve is normally closed and begins to open when the inlet port pressure reaches the preset level, directing flow to the tank port to maintain desired pressure levels. It features a vent port that allows for remote control through other pilot or 2-way valves, offering flexibility in various applications. The RVGAMGV is noted for its accuracy, smooth operation, low noise levels, and moderate response speed. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 60 gpm (240 L/min). The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen. It is crucial to note that this valve is not suitable for load-holding applications due to potential spool leakage. Additionally, back pressure at the tank port directly affects the valve setting at a 1:1 ratio. This model incorporates Sun's floating style construction to prevent internal binding from excessive installation torque or machining variations. The valve can be adjusted with an internal hex screw and secured with a locknut, ensuring precise control over settings. The RVGAMGV can be configured with EPDM seals for use with phosphate ester fluids; however, these seals are incompatible with petroleum-based substances. With a typical response time of 10 ms and minimal leakage under specified conditions, this cartridge is ideal for applications requiring reliable pressure control without experiencing significant leakage or performance degradation.
