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.

TECHNICAL FEATURES
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.
Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require different clearances.
