What's mean of PE+FNPT
(OP)
Who can give me a hand? I received a inquiry from UK, the content is below:
3/4" Ball valve(800#,full bore,PE×FNPT)
I know PE×FNPT is connection type,
FNPT stand for Female NPT(National standard pipe taper thread),however I don't know what's mean of PE. Who knows the abbreviate PE.

This is then a drain or vent valve.

The pipe is Socket weld?
Thanks

RE: What's mean of PE+FNPT
PE stands for Plain End, which means that the end connection is a straight part (e.g. by means of a welded in Nipple or integral machined to forged body) with straight end, so no bevel machined to it.
This type of end connection specified for socket weld piping systems.
FNPT is indeed Female NPT on the other end.
Your valve is most probably a block valve before an instrument device.
Good Luck.

Thank you very much for the answer
I haven't seen this type before.
Please confirm whether is attached type.
Thanks a lot.

RE: What's mean of PE+FNPT
Yes the sketch shows the correct type. Note that the PE part must have sufficient length in order to avoid melting of the soft seats/seals and to enable execution of welding.
Normally a minimum length of 75 to 100mm will be applied.
Success.

- tap the PE?
- undo the top bolts and swing the body down while welding?

I've seen those too, but I just can't see a use for the plain end on the picture.
Ashereng,
That may be right, but WHAT A PAIN.
