89-Type – – Gemini 89 Series offers 1/4” – 2” three piece ball valves with pipe socket
weld, pipe butt weld, female screwed (NPT, BSPT & JIS) end and tube
socket weld along with tube compression connections. Standard material
of construction is 316 stainless steel.
The 89 Series overcomes many common three piece ball valve installation
problems. For example, rotational alignment of the bolt holes is not
required at installation of the pipe adapters as with conventional three piece
valves. The pipe adapters, although factory assembled as integral units,
allow the flanges to rotate independently of the pipe connectors. This construction
eliminates the possibility of distortion of the pipe connector sealing
face, should the assembly bolts be overtightened.
