Product Details
The 8" T-337AB-G ductile iron wafer butterfly valve is designed with an aluminum bronze disc and gear-operated mechanism, featuring a Buna epoxy-coated wafer body that facilitates easy positioning between flanges. Its extended neck is suitable for most piping insulation applications and allows for bi-directional flow, with 100% factory testing ensuring quality. The valve includes a rigid, phenolic-backed seat that provides positive, bubble-tight shutoff, and a raised seat face that eliminates the need for companion flange gaskets. It has a cold working pressure (CWP) of 200 PSI and can withstand maximum service temperatures of up to 180°F at 200 PSI or less when not in contact with steam. The flange connection of the valve's body adheres to ANSI Class 125/150 flange dimensions. Additionally, it is manufactured in an ISO accredited facility and complies with the following standards: MSS SP-67, API 609, AWWA C504, and EN 593.
