The Sun Hydraulics RBAAYAN (RBAAYAN) is a direct-acting, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. It is essential for applications where load holding is required, and it operates by managing pilot flow in conjunction with higher flow valves. The unit features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various environments. Additionally, it incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or cavity machining variations. This cartridge valve supports back pressure on the tank port at a 1:1 ratio to the valve setting and can be configured with EPDM seals for use with phosphate ester fluids\u2014though caution should be taken as exposure to petroleum-based fluids can damage these seals. For corrosive environments, corrosion-resistant options are available with external stainless steel components or zinc-nickel plating. The RBAAYAN model has a capacity of 0.5 gpm (2 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). With a typical response time of 2 ms and minimal leakage rates, this valve is both efficient and effective. The adjustment range is controlled by up to five clockwise turns to increase settings, providing flexibility in operation. Installation requires specific torque settings for both the valve itself and its locknut to ensure optimal performance. Overall, this product offers robust performance for controlling pressure in hydraulic systems where precise management of flow and pressure is critical.
