Product Description

The MUELLER INDUSTRIES a-2361-23 is a resilient wedge gate valve rated for 350 psi maximum working pressure, designed for potable water distribution systems. Available in sizes ranging from 3 inches through 12 inches, this valve features a non-rising stem (NRS) configuration and standard mechanical joint ends that comply with ANSI/AWWA C111. Interior and exterior surfaces receive a nominal 10-mil Pro-Gard Fusion Bonded Epoxy coating meeting ANSI/AWWA C550 requirements. The fully encapsulated iron wedge leaves no exposed iron, and a triple O-ring seal stuffing box provides reliable sealing performance. Licensed plumbers and waterworks contractors are the typical installers for this product.
