Pipe Support for motor operated valve

Pipe Support for motor operated valve

Pipe Support for motor operated valve

(OP)
Hello all,

I am working on a project that replaces a 2-inch NPS gate valve with a motor operated valve.  The new valve and actuatuator has a weight of 100 lbs.  The 2-inch piping is 90-10 copper - nickel with a min wall of 0.065.  The system has a design pressure of 150 psig and temperature of 160F.

I am concerned that the extra weight might over stress the piping.  Is there a method to evaluate or a hand calculation that can be used to determne the need and placement of a valve/piping support?

Thanks

RE: Pipe Support for motor operated valve

let your piper do the calculations, but have him support the valve

RE: Pipe Support for motor operated valve

Supporting an MOV off a small bore line is a hassle -especially if there's any thermal expansion to speak of, but it's well worth it.

RE: Pipe Support for motor operated valve

If the line is as small as what you have indicated then it will become mandetory for supporting the valve actuator
