High temperature and high-pressure gate valves, due to long-term operation in harsh working conditions (temperature ≥ 343 ℃, pressure ≥ 10MPa), often experience failures related to material performance degradation, seal failure, structural stress, and medium corrosion. The following are common fault...

The pressure rating and temperature rating of American standard gate valves are mainly determined based on standards such as ASME B16.34 "Valve Flange Connections, Threaded Connections, and Welded Ends", and their design needs to meet the requirements of pressure and temperature coordinati...

The overlap between manual gate valves and globe valves in application scenarios is mainly reflected in the interception control of fluids and some common scenarios under moderate working conditions, as follows:1. Universality of fluid cutoff functionThe opening and closing control of pipeline syste...

The sealing effect of manual gate valves depends on the working conditions (pressure, temperature, medium characteristics) and sealing requirements. There is no "absolute best" method, and it needs to be selected based on specific scenarios. The following are mainstream sealing treatment m...

The sealing principle of high-temperature and high-pressure gate valves is based on the design of the sealing pair structure, material performance matching, and load transfer mechanism. By responding to thermal deformation at high temperatures, sealing pressure requirements at high pressures, and me...
