NAF Setball (v-port)
The NAF Setball (v-port) is a ball sector valve with metal-to-metal or metal-to-PTFE seating. It combines the best control characteristics of a ball valve and a butterfly valve, making it suitable as both a control valve and a shutoff valve. The NAF Setball (v-port) is available as standard in stainless steel but can also be supplied in other materials such as CG8M, Titanium, etc.
This valve features a one-piece, leak-proof stainless steel body, a V-shaped sector for accurate control, and PTFE lined bearings. It also includes a standard Stellite seat that can be converted to PTFE without dismantling the valve.
