Parts List
Model 51
Single Limit Switch
The Model 51 Single Limit Switch provides visual indication of
valve position, as well as remote electrical indication of "valve
open" or "valve closed". The single pole double throw Micro-
Switch can be connected to open or close an electrical circuit
when the valve opens or closes.
The adjustable collar is normally set to contact the trip arm when
the main valve is closed. The collar can be positioned on the stem
by loosening the set-screw to actuate the switch at the desired
point of valve travel.
