General Information for Post Indicator Valves and
Butterfly Valves
1. Model PIBVEXP is designed for installation in a
tapped hole and located so that the actuating lever of the
switch engages the target or flag of the valve . The switch
actuating lever is spring loaded against the flag or target of
the valve and is released when the valve moves toward
the closed position from the fully open position.
2. Model PIBVEXP is equipped with a removable
pipe nipple which is locked in place with two set screws.
A hex wrench is provided for this feature. These models
also include an adjustable length actuating lever which
eliminates any need for alteration of the length of the lever.
