SUN HYDRAULICS Electro-proportional relief valve – pilot capacity(RBAPXAN)

This 2-port, pilot-stage, direct-acting relief cartridge is an electro-proportionally controlled, pressure regulating valve. The proportional control allows for infinite, step-less adjustability within the selected pressure range. When the pressure at port 1 (inlet) is sufficient to overcome the solenoid forces, as determined by the analog input signal, the poppet lifts and allows flow from port 1 to port 2 (outlet). This pilot control cartridge utilizes the T-8A cavity so it can be used in conjunction with Sun’s main stage, pressure control elements.

• Varying the analog input signal to the proportional solenoid provides a step-less control of pressure.
• This electro-proportional cartridge utilizes the Sun T-8A, 2-port cavity making it the ideal choice to use in conjunction with Sun’s main stage cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-port pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
• All pressure ranges will drop to a setting of 0 with no analog input signal. The pressure ranges indicate the valve’s area of acceptable performance.
