Product Details
The 12" T-337AB-G ductile iron wafer butterfly valve features an aluminum bronze disc and is gear operated, with a Buna epoxy coated wafer body designed for easy positioning between flanges. Its extended neck allows for clearance in most piping insulation applications, and it facilitates bi-directional flow. Each unit is 100% factory tested to ensure quality, while the rigid, phenolic-backed seat provides a positive, bubble-tight shutoff. Additionally, the raised seat face eliminates the need for companion flange gaskets. Key specifications include a cold working pressure (CWP) of 200 PSI, compatibility with media types other than steam at maximum service temperatures of up to 180°F at 200 PSI or less, and flange connection features that 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.
