Sempell Fasani Style A High Pressure Check Valve
The Sempell Fasani Style A High Pressure Check Valve by Emerson is a heavy-duty, non-return valve engineered to prevent backflow and ensure reliable performance in extreme pressure and temperature conditions
The Sempell Fasani Style A High Pressure Check Valve, developed by Emerson, is a robust, non-return valve designed to ensure reliable flow control and protection in high-pressure and high-temperature applications. Engineered for power generation, petrochemical, and refinery systems, this valve prevents backflow and maintains process integrity under the most demanding operating conditions. Manufactured from forged or high-quality cast steel, the Fasani Style A check valve provides excellent resistance to pressure, temperature, and corrosion, making it ideal for use with steam, gas, and aggressive media. The precision-guided disc design ensures quick and secure closure, minimizing water hammer and system shock while maintaining tight sealing performance. Built to meet ASME, DIN, and API standards, the valveās compact and heavy-duty construction guarantees long service life, reduced maintenance needs, and dependable operation even in cyclic or pulsating flow environments. The Sempell Fasani Style A is available in a range of materials, seat options, and pressure classes to suit various system requirements.

Feature of Sempell Fasani Style A High Pressure Check Valve
- A range of pressure seal Check Valves designed according to ASME B16.34.
 - Available in Swing Check, Tilting disc and Piston Check (Y and T pattern design)
 - All range is offered in all the material stated in the ASTM specifications, and designed to always guarantee the maximum safety and flow efficiency.
 - End to end dimensions as per ASME B16.10
 - Swing and tilting disk check valves can be installed on both horizontal and vertical (up-flow) piping.
 - Stop check valves (Y and T patterns) are designed to be installed on horizontal piping.
 - Tilting disc check valves are designed utilizing triple offset seat geometry to prevent the disc slamming, stable disk operation and to ensure, at the same time, a quick closing service.
 - Tilting disc seat is manufactured directly in the body therefore removal of seat/body welding avoids distortion of seat face.
