Features

Swing check valves can fit on both horizontal and vertical (up-flow) piping.

Lift check valves are designed to be installed on horizontal piping or, with the aid of a spring, on vertical piping. They can also offer a quick closing service type.

Tilting disc check valves are designed to prevent the disc slamming and to ensure, at the same time, a quick closing service.

Standards for check valves design manufacturing are ASME B16.34 and BS 1868.

Robust valve body in a wide range of materials (NACE compliance included).

Threaded seat rings facilitate maintenance and/or replacement. On request, they can also be supplied as tack or seal welded. Above NPS 24 seats are seal welded as standard.

Connections are offered as flanged, buttweld or special, such as clamp type, to meet any customers’ request.
