DESCRIPTION
8 size, 3/4-16 thread, “Power” series, solenoid operated, 2 way normally closed, pilot operated soft seat poppet
valve with reverse ow de-energized.
OPERATION
When de-energized the PB-S2F blocks ow from (1) to (2) and allows reverse ow from (2) to (1). When energized
the valve allows ow from (1) to (2) and restrict ow from (2) to (1).
OPERATION OF MANUAL OVERRIDE OPTION: to override, pull knob out. On the detented version, after
pulling knob out twist 180 degrees and release. The valve will remain in that position.
