spectacle and butterfly valve was created by jhsunny09
I put a spectacle just after a butterfly valve, that is: flange-butterfly valve-spectacle-flange. I think it should be ok. Is there any one has a different opinion about this?
thanks for your reply.

Do it once and Do it Right

NO!!. It is NOT alright.
Yes the spec blind would normally be inserted in the "Closed" position when the valve is closed.
However, in the closed position the Spec Blind will prevent the Butterfly Valve from opening. And, if someone really tries to force the valve open then they could break the valve.

"Stupidity"
Just because it is logical that someone should not do something does not prevent the stupid one from trying.

another question: have you seen a spectacle connect with an orifice directly? It looks wired....
thanks Jop.

sorry, the orifice is a flow element, not a restriction orifice.
