Universal Cast Steel Check Valves are engineered and manufactured in strict compliance with international standards including API 6D, BS 1868, ASME B16.34, or their equivalents. These valves are specifically designed to minimize flow resistance and pressure drop, making them ideal for horizontal installation only.
The seat ring is lapped and screwed in to ensure a tight shutoff and extended service life. The valve disc is precisely designed, accurately machined, and guided to provide efficient automatic closure at zero differential pressure.
Featuring a compact structure and low-emission service capability, the standard swing check valve configuration includes a bolted cover and a free-swinging clapper, which acts as the closing member in response to flow conditions. While swing check valves are best suited for horizontal pipelines, heavier disc designs may experience chattering. In such cases, dampers or counterweights are recommended for stable operation.

Product Features

» Prevents Backflow: Cast steel swing check valve is designed to prevent reverse flow in the pipeline. Media flows in a straight path through the valve, minimizing pressure drop. The disc swings open with forward flow and closes tightly under back pressure.
» Flexible Installation: Suitable for horizontal or vertical piping, provided installation follows the flow direction indicated by the arrow on the valve body.
» Optional Accessories: Available with a range of accessories, including bypasses, locking devices, counterweights, and more, to meet specific customer requirements.
