The flange holes of the wafer ball valve have threads built-in; how should the bolts be installed?
Thread Content
I would like to ask everyone: for this type of Q71F-16P wafer ball valve, the flange holes on it are threaded. Is this the correct way to install it? Is it still necessary to use fully threaded studs for penetration?
Use single-headed stainless steel bolts, with a length that exceeds the flange by two to three threads
This is an Italian-style thin-ball valve
Professionalism is evident at a glance.
It should be possible. Because the two halves of a regular ball valve are also fixed with nuts at one end each.
It’s not possible to install this with full threading penetration.
It cannot be installed with studs running through it; can it be called a clamp-type design? Is the model wrong?
The flange is naturally a through-hole, but the ball valve has screw holes, so it cannot be clamped using studs.
This is not called a butt joint; it cannot allow penetration
