The Sun Hydraulics RBATQAV (RBATQAV) is a direct-acting, pilot relief cartridge valve designed to remotely control the pressure setting of other pilot-operated valves. It is particularly suitable for load holding applications, where precise pressure control is essential. This valve features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various conditions. It incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge. The RBATQAV model has a capacity of 0.25 gallons per minute (1 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). It exhibits a typical response time of 2 milliseconds and has a maximum valve leakage of 5 drops per minute (0.3 cc/min) at 110 SUS (24 cSt). The adjustment mechanism allows for up to 5.5 clockwise turns to increase the pressure setting, providing flexibility in tuning the valve to specific application requirements. Installation specifications for this model include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30 to 35 lbf-ft (41 to 47 Nm). The adjustment screw features an internal hex size of 5/32 inch (4 mm), while the locknut has a hex size of 9/16 inch (15 mm) with a torque range of 80 to 90 lbf-in (9 to 10 Nm). Weighing just .30 lb (.15 kg), this compact yet robust valve is an ideal choice for systems requiring reliable pressure control under varying backpressure conditions, which are directly additive at a 1:1 ratio with the tank port's backpressure.
