Sun FPB Flex Pilot Operated normally Closed Electro-proportional Throttle

This valve is a pilot-operated, normally closed, electro-proportional throttle with reverse free-flow check. Energizing
the coil generates an opening force on the pilot stage which vents the main stage poppet to open proportionally,
allowing flow from port 2 to 1. In the open condition, flow from 1 to 2 will cause the valve to auto-close and only pilot
flow will pass from 1 to 2.Hysteresis (with dither) 15%
