The pressure rating and temperature rating of American standard gate valves are mainly determined based on standards such as the American Society of Mechanical Engineers (ASME) and the American Petroleum Institute (API), which need to be comprehensively considered in combination with material charac...

Reducing the operating torque of manual gate valves requires starting from multiple aspects such as design, materials, structure, lubrication, and maintenance. The following are specific methods and strategies:1、 Optimize valve design and structure1. Improvement of sealing surface designReduce the...

The temperature rating of American standard gate valves (following ASME, API and other standards) is closely related to material properties and medium characteristics, and different temperature ranges correspond to specific material selection and application scenarios. The following are classified i...

There are significant differences between American standard gate valves (following ASME, API and other standards) and national standard gate valves (following GB, JB and other standards) in terms of pressure rating and temperature rating systems, mainly reflected in system architecture, representati...

The maintenance and upkeep of the sealing surface of American standard gate valves (following ASME, API and other standards) should be based on their design characteristics (such as wedge gate, parallel double gate structure) and operating requirements (high temperature, high pressure, corrosion, et...
