The Sun Hydraulics RVGALCV (Material Number: RVGALCV) 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 2 when the pressure at inlet port 1 reaches a predetermined setting, effectively throttling flow to maintain desired pressure levels. Featuring a vent port 3, it allows for remote control by other pilot or two-way valves. Known for its accuracy and smooth operation, this valve is suitable for cross-port relief circuits, although spool leakage should be considered in such applications. It is not recommended for load-holding applications due to this leakage. The main stage orifice of the RVGALCV is protected by a 150-micron stainless steel screen, ensuring reliability and longevity. The valve can handle a maximum operating pressure of 5000 psi (350 bar) and supports a capacity of up to 60 gpm (240 L/min). It incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. This model includes EPDM seals suitable for systems using phosphate ester fluids but is incompatible with petroleum-based fluids and lubricants. Back pressure on tank port 2 directly affects the valve setting at a 1:1 ratio. The valve includes features like an adjustment screw with internal hex size of 5/32 inch (4 mm) and locknut torque ranging from 80-90 lbf-in (9-10 Nm). With its robust design and reliable performance characteristics, the Sun Hydraulics RVGALCV cartridge is ideal for applications requiring moderate speed and low-pressure rise versus flow dynamics.
