Duplex stainless steel valves are celebrated for their outstanding performance in harsh environments, thanks to their material properties and meticulous design. They are widely used in demanding industries such as marine engineering, petrochemical processing, and mining equipment. The excellence of duplex stainless steel comes from its unique microstructure and balanced composition; the solid solution structure contains approximately 50% ferrite and 50% austenite phases, typically ensuring that...

When installing electric actuated valves, ensuring the proper coordination between the valve and the electric actuator is crucial. An electric actuated valve is a system that combines the valve and the actuator, and the installation and operation of the actuator depend largely on the correct installation of the valve. To ensure that the electric valve operates smoothly and accurately after commissioning, it is not only essential to install the actuator according to the guidelines but also to pay...

The production process for industrial valves combines both complexity and systemization, generally involving multiple stages from raw material preparation to final product testing. Common types of valves typically take about three days to manufacture. However, to ensure reliability and safety in real-world applications, finished valves must undergo rigorous performance testing, with pressure testing being among the most critical. Pressure testing is designed to verify whether an industrial valve...

Pneumatic hard-seal ball valves are widely used in various industrial processes, including oil, chemical, metallurgy, power, and water treatment, due to their excellent sealing performance and durability.
