The Sun Hydraulics RBATTAN (Material Number: RBATTAN) is a direct-acting, pilot relief cartridge valve designed to remotely control the pressure setting of other pilot-operated valves. This valve is optimized for applications where capacity is limited to pilot flow and should be used in conjunction with higher flow valves. It features a main stage orifice protected by a 150-micron stainless steel screen, making it suitable for load holding applications. The valve's design incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge. Notably, back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio. The RBATTAN model fits into Cavity T-10A and offers a series 1 capacity of 0.25 gpm (1 L/min) with a maximum operating pressure of 5000 psi (350 bar). It boasts a typical response time of 2 milliseconds and has a maximum valve leakage rate of 5 drops/minute (0.3 cc/minute) at 110 SUS (24 cSt). The adjustment mechanism allows for up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. The valve has a hex size of 7/8 inch (22.2 mm) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). The internal hex size for adjustment is 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm), with a locknut torque range of 80 - 90 lbf in (9 -10 Nm). Weighing approximately .30 lb (.15 kg), this model also comes with an optional Viton seal kit under part number: 990010006.
