OMNI 250 SERIES VALVESAir Pilot OperatedThe OMNI Series 3-Way and 4-Way valves can be air pilot operated with three typesof assembly.1. DOUBLE AIR PILOT (NO VALVE SPOOL SPRING) The valve spool is shifted bya momentary air pilot signal to either of the “A” or “B” Pilots.2. SINGLE AIR PILOT, SPRING RETURN The valve spool is maintained in thenormal rest position in the “B” end. A maintained air pressure signal at the “A” endgreater than the spring force will shift the valve spool.3. DOUBLE AIR PIOT, SPRING OFFSET The valve spool is maintained in thenormal rest position in the “B” end. A maintained air pressure signal at the “A” endgreater than the spring force will shift the valve spool, providing no air pressuresignal is on the “B” end. By controlling the pressure differential between “A” and“B” a variety of applications are available.Air Pilotspring returnDouble airpilotDouble airpilot springoffsetBasic Valve Model NumbersPipe Size Number Schematics1/8 NPTF 250-02-011-031/4 NPTF 250-02-001-031/8 NPTF 250-03-011-031/4 NPTF 250-03-001-031/8 NPTF 250-04-011-031/4 NPTF 250-04-001-03DoubleAir PilotNote: For 3-Way body see page 4503 Air PilotNote: Bases ordered separately32
