Product Details
The 8" T-337DI ductile iron wafer type butterfly valve features Buna seats, a ductile iron disc, and a heavy-duty, lockable ten-position handle. Its epoxy-coated wafer body facilitates easy positioning between flanges, and the extended neck is designed to accommodate most piping insulation applications. This valve supports bi-directional flow and is 100% factory tested to ensure reliability. The rigid, phenolic-backed seat provides a positive, bubble-tight shutoff, while the raised seat face eliminates the need for companion flange gaskets. Key specifications include a cold working pressure (CWP) of 200 PSI, with special order disc options available as T-335DI and T-337DI in ductile iron. The valve's flange connection conforms to ANSI class 125/150 flange dimensions. It is manufactured in an ISO accredited facility and adheres to the following standards: MSS SP-67, API 609, AWWA C504, and EN 593.
