Air Pilot Operators
DIE34A DIE341A Air Pilot Operators
Model 34A and 341A air pilot operators thread directly onto the collars of
push-button valves and the Model ESB Electric Switch Bracket. The air
pressure applied to the pilot port drives a V-cup sealed piston to actuate
the valve s push-button. The 341A air pilot operator provides
approximately twice the actuation force of the 34A at the same pilot
pressure and is used for lower pilot pressure requirements or to amplify
weak pilot signals, especially to 41PP and 42PP valves with positive
detents.

DIE34AS DIE341AS Air Pilot Operators with Snap
Action
Model 34AS and 341AS air pilot operators thread directly onto the collars
of push-button valves and the Model ESB Electric Switch Bracket. They
are used primarily for time-delay circuits and other slow-building pilot
pressure applications. The actuation of the operator is delayed until pilot
pressure reaches 35 psig – 5 psig. At this pressure, the operator piston
snaps forward to actuate valve or switch and remains shifteduntilpilot
pressure is exhausted. Maximum cycle life is obtained at 40-65 psig, 125
psig maximum.
Humphrey manual valves are 2-way, 3-way and 4-way valves featuring high flow and full orifice throughout their internal chambers. Simply designed for
high reliability in rugged use, these compact valves require no lubrication. Bottom inlets are available for normally closed valves (except 250-4H and
501V valves). A 125 Series valve has a full 0.125-inch orifice. A 250 Series valve has a full 0.250-inch orifice. A 250 Series valve has a full 0.250-inch ori-
