The Sun Hydraulics RVCAQBN (RVCAQBN) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure in hydraulic systems. This normally closed pressure regulating valve opens to the tank port when the inlet pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. It features a vent port for remote control via other pilot or 2-way valves, ensuring precision and smooth operation with minimal noise and moderate speed. Notably, this valve can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The RVCAQBN model is equipped with a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction to prevent internal binding due to installation torque variations. It is important to note that this valve is not suitable for load-holding applications due to potential spool leakage. The back pressure on the tank port directly affects the valve setting at a 1:1 ratio. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended, as exposure to petroleum-based fluids may damage these seals. The valve has a cavity type T-11A and operates efficiently with a capacity of up to 15 gpm (60 L/min) at maximum pressures of 5000 psi (350 bar). It features an adjustment range facilitated by an internal hex screw and locknut system, allowing precise control over settings. With its robust design and reliable performance characteristics, the Sun Hydraulics RVCAQBN offers an effective solution for various hydraulic applications requiring accurate pressure regulation and remote control capabilities.
