Fabri-Valve CF134 Bonneted Knife Gate Valve
The Fabri-Valve C/F134 bonneted knife gate valve is used in difficult services to provide high cycle stem sealing and superior stem seal containment. The cylindrical packing around the stem provides a tighter, easier to maintain stem seal. Bonneted valves are available with an optional metal backseat on the stem, and can be supplied with a gate wiper and purge ports in the bonnet. Standard body materials include Figure 304, 316 and 317L stainless steel, with special alloys such as 254 SMO and Hastelloy C also available.
