Solenoid valve bolted onto a butterfly valve (commercial)

[Scott_D]

I have been told you can no longer bolt a gas solenoid valve onto a 1/4 turn butterfly valve. There must be a section of pipe inbetween.
The regs have recently changed.

anyone heard this?

New one on me Scott. I haven't seen or heard owt.

It may well be bull shoot then.
Mine expires in November
