pressure. DIAPHRAGM is reduced, loading the DIAPHRAGM ASSEMBLY
in a down direction. The accelerated downward movement of the
DIAPHRAGM ASSEMBLY produces a sudden opening of the
Supply Pressure inlet (Violet to Yellow).
SUPPLY PRESSURE: In order to reverse the above action, the upward force of the
5 to 30 psig LEVER on the Diaphragm Assembly must be greater than the
force of the BOOSTER SPRING plus Supply Pressure (Violet)
acting on the full area of the SNAPPER DIAPHRAGM. As the
Diaphragm Assembly moves up, the Supply Pressure inlet is
closed first. The PILOT PLUG SPRING holds the lower ball
against its seat while a further upward movement of the LEVER
opens the pressure vent (Yellow to Atmosphere). Decreasing
Output Pressure (Yellow) accelerates the upward movement of
the Diaphragm Assembly to produce a sudden opening of the
pressure vent. The sudden changes in Output Pressure (Yellow)
caused by movements of the LEVER, snap actuates any motor
valve to which it is connected.
For throttling Service, connect Supply Pressure (Violet) to
opening marked “THROT” on the pilot body. This will require
changing the pivot on the LEVER or reversing the motor valve
action. The supply gas connection for snap service becomes the
exhaust for throttling service.
