The Sun Hydraulics RVBALNN (Material Number: RVBALNN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. It operates by remaining normally closed until the inlet port pressure reaches the predetermined valve setting, at which point it opens to the tank port, throttling flow to maintain desired pressure levels. This model features a vent port that allows for remote control through additional pilot or two-way valves. Known for its accuracy and smooth operation with minimal noise, it offers a moderately fast response and low-pressure rise versus flow characteristics. The valve is capable of handling maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such applications. It is not recommended for load-holding applications due to potential leakage. The valve\u2019s back pressure on the tank port directly affects the valve setting at a 1:1 ratio. The RVBALNN incorporates Sun's floating style construction to reduce the risk of internal component binding due to installation torque or machining variations. It boasts a protected main stage orifice against contamination and has a capacity of 7.5 gpm (30 L/min) with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). Typical response time is around 10 ms, with maximum valve leakage at 2 in\u00b3/min (1000 psi). Adjustment features include up to five clockwise turns to increase settings, along with specific hex sizes and torque specifications for installation and locknut adjustments. This model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits for optimal performance.
