Product Details
The 5" T-303 OS & Y cast iron gate valve features an outside-screw-and-yoke stem design that provides a visual reference to the disc wedge position and enhances durability compared to non-rising stem designs, as the stem threads are external and not exposed to media flow. It includes class 125/150 flange-type end connections and an IBBM (Iron-Body-Bronze-Mount) design with bronze seat and wedge sealing rings. The solid wedge ensures a positive drip-tight closure while the durable cast iron construction resists pipeline stresses and distortion. All external surfaces are primed and dual-coat painted for corrosion resistance, and the full-flow waterways are designed to minimize pressure drop. The working pressure specifications are as follows: cold working pressure (CWP) is 200 PSI, and saturated steam (WSP) is rated up to 125 PSI at 450°F. The face-to-face dimensions comply with ANSI/ASME B16.10 requirements for interchangeability, and the flanged end connections adhere to ANSI/ASME B16.1 Class 125/150 standards. Additionally, this valve conforms to MSS SP-70 and is manufactured in an ISO-9002 accredited facility.
