The structural design of American standard gate valves (following API, ASME, and other standards) directly determines the contact accuracy, load distribution, and adaptability of the sealing pair, which in turn affects the sealing effect. The following analyzes the impact of core structural design e...

Improving the sealing performance of American standard gate valves (following API, ASME and other standards) requires comprehensive optimization from multiple aspects such as design, materials, manufacturing, installation and maintenance. The following are specific methods:1、 Optimization of sealin...

The material selection of high-temperature and high-pressure gate valves should meet the requirements of high temperature resistance (usually>450 ℃), high pressure resistance (PN100~PN420 or Class 600~Class 2500), creep resistance, oxidation resistance, and medium corrosion resistance, mainly inv...

When selecting suitable valves for high temperature and high pressure gate valve manufacturers, they usually consider the following aspects:Medium characteristicsTemperature: Clarify the working temperature range of the medium. Generally speaking, for sub high temperature media between 325-425 ℃, ma...

The difference between manual gate valves and other types of valves (such as ball valves, butterfly valves, globe valves, etc.) mainly lies in the following aspects:Structural principleManual gate valve: The gate of the gate valve moves in a straight line inside the valve body, and the valve is clos...
