POSITION INDICATOR (Model 745PI)

 

The optional valve disc Position Indicator (PI) mechanical indicator is factory (see 
Fig 4) installed but can also be installed in the field.  The Position Indicator visually 
indicates to what degree the valve disc is opened or closed.  The device is 
installed on the access cover and can be installed in the field by going through 
the following steps: 
1. Remove pipe line pressure and drain the valve. 
2. Carefully, remove the top pipe plug (insuring that there is no water pressure in 
the line) from the access cover. 
3. Apply pipe joint compound to position indicator body (11) threads.

 

 

4. Insert the position indicator body (11) and thread in-place.  

 

 
 
 
 
 
 
 
 
 
 

WARNING: Make sure that the position indicator top portion after securely installed pointes in the valves 
flow direction.  This will ensure proper orientation and function of the position indicator assembly.  Damage 

to the device and valve disc will accrue if the position indicator is not correctly and exactly aligned with the valves 
flow direction.  

 

Limit Switch (Model 745LS) 

The limit switch option (Model 745LS) is factory 
installed or field installed (see Fig 5a & 5b) on the 
valve access cover and is used in conjunction 
with the Position Indicator (PI). A standard limit 
switch (Honeywell Model LSH1A or Equal) is 
mounted on an epoxy coated steel bracket 
for easy wiring, field adjustments and 
servicing.  The limit switch is SCADA 
(Supervisory Control and Data Acquisition) 
compatible for applications requiring open/close 
indication. 

 

Function:

 The limit switch when probably adjusted will give an electric 

“closed” and/or “open” circuit when valve is open and/or in closed position. 

 

NEMA Ratings: 1, 3, 4, 4X, 6, 6P, 12, 13 
UL Ratings: 6 A, 120Vac or 250 Vac, DPST 

 

 

Installation: 

1. First, make sure that the valve is equipped with a Position Indicator (PI). 
Attach limit switch bracket (7) with assembly to Position Indicator (PI). 
2. Position the assembly so that the switch trips when the valve is closed. 
3. Connect wiring to either the normally open or normally closed contact as 
shown in the schematic diagram.  Follow all local electrical codes.
