Product Description

Introduction

American standard bellow seal gate valves are designed and manufactured in accordance with American standards.  These valves are used to cut off or connect the medium in the pipeline. The valve stem of the bellow seal gate valve adopts a double - seal structure of bellows and packing, which ensures a leak - free seal at the valve stem. The bellows are made of stainless steel or Inconel materials, with a reasonable sealing structure design, high fatigue resistance, and a long service life

Advantages

Bellow is the key part of bellow sealed valves, which is welded to the the valve bonnet and valve stem, with automatic roll welding. The metal bellow can keep the stem part 100% no leakage.
Double seal design(bellows + packing). Bellow form a metal seal to prevent leakage, and packing can provide seal if the bellow failed.
