Opt.29 valve

Opt.29 valve

Opt.29 valve

(OP)
Dear Experts,

What is meaning of opt.29 shown in top of valve which is installed upstream of a thermal relief valve?

Thank you if someone shed some light in my question.

Cheers

RE: Opt.29 valve

Where did you see this?
can you give some more details?

RE: Opt.29 valve

(OP)
I saw this in the P&ID.

Cheers

RE: Opt.29 valve

Maybe it refers to a locking system, a valve before and after a safety should be locked open.

RE: Opt.29 valve

You need to get the legend/symbology pages for the company's P&IDs.

Good luck,

To a ChE, the glass is always full - 1/2 air and 1/2 water.

RE: Opt.29 valve

At a guess it means option number 29.

Often p&ids have many standard configuration of valves. As others say? get the symbol legends sheets and have a look.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Dear all,

Thank you for your replies.

I don't have symbol and legend sheet yet, but when I google it it's reach to this result:

http://www.rlmracing.com/4-guide-valve-os-03-opt-1...

which shown "GUIDE, VALVE (OS 0.3) OPT 11115-29G70"

As most of valves in PSV inlet/outlet lines should be Full Bore, do you think there is relation

of valve type and e.g. reduced bore, full bore,... and OPT?

Cheers

RE: Opt.29 valve

It can be anything, if we just google the word without any specific meaning or criteria.
Your link refers to automotive car parts... I got something completely different: http://www.thomasnet.com/catalogs/item/129415-1579... and none of them seem to apply to what you have there.

As others said, you need to find the legend sheet or talk to a person who made the P&ID.

Option 29 doesn't have a standard meaning. What we think, given so little information, isn't relevant. This is the internet. You are not connected to the Wizard of Oz, or any higher authority. smilesmilesmile
