Torque Switches in MOV

"MOV" - motor-operated valve?

To stop the valve motor when the shaft torque passes a predetermined setpoint.

I was wondering what a torque switch would have to do with a metal oxide varistor.

Take a wild guess.

It's probably worthwhile to note that acronyms mean different things to different people. When somebody posts MOV with very little context in the instrumentation section, I had to pause to wonder what it meant. My first inclination with electrical background is a Metal Oxide Varistor. For those to mark your relevant response off-topic is petty. I went ahead and posted an OTOR for you.

I too was amused by the bully's antics.

Gentleman, pls expand MOV

thank you very much now i can understand about torque switches

You took good amount of pain in making MOV explaination but this Anonymous Poster # 1 is no more in this blog. Unfortunately people do not understand value of time.

You done a good work but is regardless unless the question poster watches your posting replies and acknowledges it.

Thanks for the wonderer and thanks for the answerer

since previous posts already cleared the use of Torque limit switch in detail. MOV's are installed in the pipeline for open, close, partially open and partially closed functions, 3 phase motor is used to rotate the stem so it is important to stop motor when valve is in fully closed or fully opened condition.

while calibrating rotork valve there are not much parameters to initialised Zero and span are the two important parameters to be configured. MOV can be on serial link (ring topology) or dedicated cables from junction Boxes can be layed going to control room PLC/SCADA.

generally, 5 signals are enough

2 signals are open and close indication.

2 signals are open and close command.

1 signal for local/remote switching

Torque limit switch will bring motor out of the circuit in either direction of rotation of valve at torque set point, this limit can be change through MOV mounted dispaly.
