Product Details
The 4" T-337AB-G ductile iron wafer butterfly valve features an aluminum bronze disc and is gear operated, with a Buna epoxy coated wafer body that allows easy positioning between flanges. Its extended neck accommodates most piping insulation applications, and it is designed for bi-directional flow. The valve is 100% factory tested, ensuring reliability. It includes a rigid, phenolic-backed seat that provides positive, bubble-tight shutoff, and its raised seat face eliminates the need for companion flange gaskets. The cold working pressure (CWP) is rated at 200 psi, and maximum service temperatures with pressures allow for compatibility 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. 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.
