Product Details
The 2-1/2" T-337SS ductile iron wafer butterfly valve features a stainless steel disc and a heavy-duty lockable ten-position lever handle, allowing for easy positioning between flanges. The Buna epoxy coated wafer body is designed for bi-directional flow and is compatible with most piping insulation applications due to its extended neck. The valve includes a rigid, phenolic-backed seat that ensures positive, bubble-tight shutoff, while the raised seat face eliminates the need for companion flange gaskets. It is factory tested at a cold working pressure (CWP) of 200 PSI. Special order disc options are available, including T-335SS and T-337SS, which use a 316 stainless steel disc. The flange connection features conform to ANSI Class 125/150 flange dimensions. This valve is manufactured in an ISO accredited facility and complies with standards such as MSS SP-67, API 609, AWWA C504, and EN 593.
