Product Details
The 3" T-337DI-G ductile iron wafer type butterfly valve features Buna seats and a ductile iron disc, with a gear-operated epoxy-coated wafer body that facilitates easy positioning between flanges. It has an extended neck design that is compatible with most piping insulation applications and supports bi-directional flow. Each valve is 100% factory tested to ensure reliability, while the rigid, phenolic-backed seat allows for a positive, bubble-tight shutoff. The raised seat face design eliminates the need for companion flange gaskets. This valve has a cold working pressure (CWP) rating of 200 PSI and offers special order disc options, specifically T-335DI and T-337DI ductile iron discs. The flange connection of the valve's body conforms to ANSI Class 125/150 flange dimensions. It is manufactured in an ISO accredited facility and adheres to the standards outlined in MSS SP-67, API 609, AWWA C504, and EN 593.
