Models 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 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 pressure requirements or to amplify weak pilot signals, especially to 41PP and 42PP valves with positive detents.
