American Standard Flanged Gate Valve

The American Standard hard-sealed, rising-stem, flanged gate valve features a metal-to-metal hard-sealing design. Depending on material requirements and operating conditions, the gate disc and valve seat can be configured with either integral seating surfaces or welded hard alloy overlays. The body-to-bonnet connection utilizes a flat-face structure for the 150LB class, while the 300LB class employs a circular-face structure.
