Product Details
The 4" T-337SS ductile iron wafer butterfly valve features an epoxy coated wafer body that allows for easy positioning between flanges, along with an extended neck to accommodate most piping insulation applications. This valve supports bi-directional flow and is 100% factory tested for reliability. It includes a stainless steel disc and Buna seats, with a rigid, phenolic-backed seat that ensures positive, bubble-tight shutoff. The raised seat face eliminates the need for companion flange gaskets, and the heavy-duty lockable ten-position lever handle enhances usability. The cold working pressure (CWP) is rated at 200 PSI, and the flange connection features of the valve's body conform to ANSI class 125/150 flange dimensions. It is manufactured in conformance with the standards MSS SP-67, API 609, AWWA C504, and EN 593, and produced in an ISO accredited facility.
