ASTM A105N Tilting Disc Check Valve, 5-1/8 Inch, 10000 PSI

Key Specifications / Features

The ASTM A105N Tilting Disc Check Valve is a high-pressure valve designed for demanding industrial applications. Manufactured in accordance with ASME B16.34 standards, it features a carbon steel body and a pressure-sealed design. The valve has a 5-1/8 inch diameter and is rated for a pressure of up to 10,000 PSI, making it suitable for high-pressure systems. It is equipped with flanged ends for easy installation and secure connections.

The disc of a tilting disc check valve is mounted on a pivot point at its center. It is designed to address the weaknesses of traditional swing check valves. Compared to a swing check valve, the tilting disc check valve can remain fully open and stable at lower flow rates. In contrast, a swing check valve requires higher fluid velocity to keep the disc open, resulting in a higher cracking pressure. For low-pressure applications, the pressure drop of a tilting disc check valve is significantly lower than that of a swing check valve. However, at higher flow rates, the tilting disc check valve experiences a higher pressure drop compared to the swing type.

Product Features

» When closed, the valve contacts the sealing surface slowly, ensuring no impact and no noise.
» Micro-elastic metal seats provide excellent sealing performance.
» Butterfly disc design allows for quick opening and closing, ensuring a long service life.
» The tilting disc structure creates a streamlined fluid passage with minimal flow resistance, offering excellent energy-saving benefits.
