The Universal Cast Steel Swing Check Valve is engineered to meet stringent international standards such as API 6D, BS 1868, and ASME B16.34, ensuring robust performance and long service life. Designed to minimize flow resistance and pressure drop, this valve is optimized for horizontal installation only. The valve features a bolted cover and a free-swinging clapper (disc), which automatically closes at zero pressure, preventing reverse flow. The lapped and screwed-in seat ring ensures a tight shutoff and enhances durability. With a compact structure and low-emission capabilities, it is suitable for demanding industrial applications. For heavier disc configurations where chattering may occur, optional dampers or counterweights can be provided to enhance stability.
