The Sun Hydraulics RVGAMWV (Material Number: RVGAMWV) 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 pressure reaches the preset level, effectively throttling flow to maintain stable pressure. It features a vent port for remote control using other pilot or 2-way valves, offering versatility in various applications. The valve is known for its accuracy, low pressure rise versus flow, smooth operation, and moderate response speed. This model can handle a maximum operating pressure of 5000 psi (350 bar) and is suitable for cross-port relief circuits with considerations for spool leakage. It incorporates a main stage orifice protected by a 150-micron stainless steel screen. However, it is not recommended for load-holding applications due to potential spool leakage issues. The back pressure on the tank port directly affects the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available; these seals are not compatible with petroleum-based fluids. The valve's construction includes Sun's floating style design to reduce binding risks from installation torque or machining variations. The RVGAMWV supports a flow capacity of up to 60 gpm (240 L/min) and has specific installation requirements including a torque specification of 150-160 lbf ft (203-217 Nm). The adjustment mechanism allows for fine-tuning with up to five clockwise turns to increase settings and includes detailed specifications for hex sizes and locknut torque requirements. This robust relief cartridge weighs approximately 1.60 lb (0.70 kg) and comes with options such as Viton seal kits for enhanced durability in various operating environments.
