ASTM A216 WCB Tilting Disc Check Valve, 2 Inch, 150 LB, RF

Key Specifications / Features

Our plant manufactures Carbon Steel Tilting Disc Check Valves in compliance with ASME B16.34 standards. These valves feature a durable ASTM A216 WCB body, available in a 2-inch (DN50) size with a Class 150 LB (PN20) pressure rating. They are equipped with RF flanged ends for secure and reliable connections, ensuring efficient backflow prevention in various applications.

The tilting disc check valve has a pivot point at the center of the disc, designed to overcome the weaknesses of conventional swing check valves. Compared to swing type check valves:

Lower Flow Rates: The tilting disc valve remains fully open and steady at lower flow rates, requiring less fluid velocity and lower cracking pressure.
Pressure Drop: At low pressure, the tilting disc valve has a much lower pressure drop than swing type valves. However, at higher flow rates, it experiences a higher pressure drop.
