EMERSONFASANI CHECK VALVES BOLTED BONNET CONFIGURATIONThe bolted bonnet type valves are manufactured to guarantee the highest performance in the widest spectrum of oil and gas applications • 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. Sizes: Temperature (°C): Pressure ratings: Body materials: The high quality valves are installed in a large variety of services in the oil and gas field, chemical and petrochemical industry, in onshore and offshore drilling/refining, and in the power industry. These valves are successfully installed worldwide on applications requiring flow reversal prevention.
