<h2>Overview</h2>
<p>The 8957-040031S-U is a Class 900 gate valve flexible wedge disc rated for 6″ nominal pipe size. This component is engineered for use in high-pressure industrial piping systems, including hydraulic, pneumatic, and general plumbing applications. <strong>Flexible wedge gate valves</strong> are specifically designed to accommodate thermal expansion and prevent binding when valve bodies experience stress from temperature fluctuations or pipe load changes.</p>
<h2>Key Features</h2>
<ul>
<li>Flexible wedge design reduces thermal binding and improves seal reliability under thermal cycling</li>
<li>Class 900 pressure rating for high-pressure service applications</li>
<li>6″ valve disc accommodates standard 6-inch line connections</li>
<li>Durable construction suitable for oil, gas, water, and industrial fluid service</li>
<li>Independent wedge halves allow accommodation of seat angle variations</li>
</ul>
