The Sun Hydraulics RBATQWN (Material Number: RBATQWN) is a direct-acting, pilot relief cartridge valve specifically designed for remotely controlling the pressure setting of other pilot-operated valves. This valve is ideal for load holding applications and should be used in conjunction with higher flow valves due to its capacity being limited to pilot flow. It features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction, which minimizes the risk of internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The valve allows back pressure on the tank port (port 2) to be directly additive to the valve setting at a 1:1 ratio. Key specifications include a cavity type T-10A, series 1 capacity at 0.25 gpm (1 L/min), and a maximum operating pressure of 5000 psi (350 bar). The typical response time is 2 ms, with maximum valve leakage at 110 SUS (24 cSt) being limited to 5 drops/min (0.3 cc/min). The adjustment mechanism allows for five clockwise turns to increase the setting, and it requires specific torque settings during installation: a valve hex size of 7/8 in. (22.2 mm), installation torque between 30 - 35 lbf ft (41 - 47 Nm), an adjustment screw internal hex size of 5/32 in. (4 mm), and locknut torque between 80 - 90 lbf in. (9 - 10 Nm). Weighing approximately .30 lb (.15 kg), this model includes compatibility with Viton seal kit number 990010006 for optimal performance and durability in various hydraulic systems.
