Universal Cast Steel Check Valves are engineered and manufactured in full compliance with international standards such as API 6D, BS 1868, ASME B16.34, or their equivalents. These valves are designed to minimize flow resistance and pressure drop, making them highly efficient for use in horizontal pipeline installations only.
Each valve features a lapped and screwed-in seat ring that ensures a tight shutoff and long service life. The disc is precisely designed, accurately machined, and properly guided to enable efficient automatic closure even at zero differential pressure. The valves also feature a compact structure and support low-emission applications.
In standard form, the swing check valve includes a bolted cover and a free-swinging clapper—the primary closing element that responds to flow direction and pressure. While ideal for horizontal pipelines, heavier disc configurations may cause chattering. To mitigate this, dampers or counterweights can be provided as optional accessories.

Product Features

» Prevents backflow in the pipeline; media flows in a straight line through the valve, ensuring minimal pressure drop. The disc swings open with forward flow and closes securely under back pressure.
» Can be installed in both horizontal and vertical pipelines, provided installation follows the flow direction indicated by the arrow on the valve body.
» Optional accessories such as bypasses, locking devices, counterweights, and other custom configurations are available to meet specific customer requirements.
