Product Details
The 12" T-337AB ductile iron wafer butterfly valve features an aluminum bronze disc and a heavy-duty lockable ten-position lever handle, providing enhanced control and reliability. The Buna epoxy coated wafer body allows for easy positioning between flanges, and the extended neck is designed to clear most piping insulation applications. This valve accommodates bi-directional flow and is 100% factory tested, ensuring quality performance. Its rigid, phenolic-backed seat guarantees a positive, bubble-tight shutoff, and the raised seat face eliminates the need for companion flange gaskets. The valve has a cold working pressure (CWP) of 200 PSI and is compatible with media types other than steam up to 180° F at 200 PSI or less. The flange connection features of the valve's body conform to ANSI Class 125/150 flange dimensions, and the product is manufactured in an ISO accredited facility while conforming to several standards including MSS SP-67, API 609, AWWA C504, and EN 593.
