Product Details
The 12" T-337DI ductile iron wafer type butterfly valve features BUNA seats, a ductile iron disc, and a heavy-duty lockable ten-position handle, allowing for versatile operation and easy positioning between flanges due to its epoxy coated wafer body. The valve includes an extended neck designed to clear most piping insulation applications and supports bi-directional flow. It is 100% factory tested, ensuring reliability, and is equipped with a rigid, phenolic-backed seat that provides positive, bubble-tight shutoff, while the raised seat face eliminates the need for companion flange gaskets. The cold working pressure (CWP) is rated at 200 PSI, and special order disc options include T-335DI and T-337DI, both made from ductile iron. Additionally, the flange connection features of the valve's body comply with ANSI Class 125/150 flange dimensions. This product is manufactured in an ISO accredited facility and conforms to several standards, including MSS SP-67, API 609, AWWA C504, and EN 593.
