The Sun Hydraulics RSJEBBV (RSJEBBV) is an air-controlled, pilot-operated, balanced piston sequence valve designed to use compressed air over a diaphragm for pressure control rather than an adjustable spring. This valve is particularly suited for applications requiring the supply of a secondary circuit with flow once the inlet port pressure exceeds the valve setting. It is engineered to maintain consistent performance by being insensitive to back pressure at the sequence port, up to the valve setting, and can regulate pressure similarly to two-port relief valves when there is return line pressure. The RSJEBBV model offers explosion-proof remote control capabilities of its pressure settings, with a hydraulic-to-air setting ratio of 20:1. It features Sun's floating style construction to reduce internal binding risks during installation or due to machining variations. The valve operates within a maximum air pilot pressure of 150 psi (10.5 bar) and can handle a maximum operating pressure of 2000 psi (140 bar). Its cavity type is T-19A, Series 4, with a flow capacity of 120 gpm (480 L/min). Factory pressure settings are established at 4 gpm (15 L/min), ensuring reliable performance in demanding conditions. The RSJEBBV has a response time typically around 10 milliseconds and exhibits minimal leakage at maximum viscosity conditions. Installation requires a torque between 350-375 lbf-ft (474-508 Nm), and it weighs approximately 3.10 lb (1.40 kg). For sealing needs, Viton seal kits are available under part number 990019006, supporting its robust design for various hydraulic applications requiring precise sequence control and reliability in operation.
