Product Details
The 4" T-335AB ductile iron wafer butterfly valve features an epoxy-coated wafer body that allows for easy positioning between flanges. Its extended neck is designed to clear most piping insulation applications, and it supports bi-directional flow. The valve is 100% factory tested and includes an aluminum bronze disc, EPDM seats, and a rigid phenolic-backed seat that ensures positive, bubble-tight shutoff. The raised seat face eliminates the requirement for companion flange gaskets, and it is equipped with a heavy-duty lockable ten-position lever handle. The cold working pressure (CWP) is 200 PSI, while the working steam pressure (WSP) is 125 PSI, making it compatible with steam up to 250° F at 125 PSI or less. The flange connection features of the valve's body conform to ANSI Class 125/150 flange dimensions. This valve is manufactured in conformance with the following standards: MSS SP-67, API 609, AWWA C504, and EN 593, and is produced in an ISO accredited facility.
