Humphrey TAC Air Pilot Operators for Push Button Valves, Pilot Operator w /Reset 8" NPT

Model 341AR air pilot actuator threads directly onto the collars of push-button valves. When used on a spring return valve, it provides a momentary "one-shot" output signal (40 psig min)which actuates the operator piston immediately. The operator's pressure- balanced piston then resets, even in the presence of a pilot signal. This reset occurs within 0.3 seconds at 40 psig, within 0.5 seconds at 100 psig and within 0.7 seconds when used with 4PP, 41PP, or 42PP valves.
