DF-S3B DIRECT ACTING SPOOL, 3 WAY 2 POSITION, SELECTOR
DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, solenoid operated, 3 way 2 position, spool valve.
OPERATION
When de-energized the DF-S3B allows ow from (3) to (2) and blocks ow at port (1). When energized the valve
allows ow from (3) to (1) and blocks ow at port (2).
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.
