The Sun Hydraulics RVBAKWN (RVBAKWN) 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 inlet pressure reaches the preset level, allowing for controlled pressure management. It features a vent port that facilitates remote control by other pilot or 2-way valves. Known for its accuracy and smooth operation, this valve offers low pressure rise versus flow and operates quietly with moderate speed. The RVBAKWN can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, spool leakage should be considered in such applications. It is not recommended for load holding due to potential leakage issues. The valve's setting is influenced directly by back pressure on the tank port at a 1:1 ratio. This model boasts a protected main stage orifice to prevent contamination and incorporates Sun's floating style construction to reduce internal part binding from installation torque or machining variations. With a cavity type of T-163A and a series 0 capacity of 7.5 gpm (30 L/min), it has factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with a control pilot flow of 7\u201310 in\u00b3/min (0.11\u20130.16 L/min) and typical response time of 10 ms. The valve's adjustment mechanism allows for up to five clockwise turns to increase setting, supported by specific hex sizes for the valve, internal adjustment screw, and locknut. The unit weighs approximately 0.30 lb (0.15 kg) and comes with an optional Viton seal kit (990163006).
