To prevent sealing failure of high-temperature and high-pressure gate valves, it is necessary to start from multiple dimensions such as material selection, structural design, installation process, operation and maintenance, and develop systematic measures based on the characteristics of working cond...

The connection structure of American standard gate valves should comply with American standards (such as ASME, API, etc.), and their design and manufacturing should meet the sealing performance, strength, and installation convenience under different working conditions. The following are common conne...

High temperature and high pressure gate valves are widely used in harsh working conditions such as petrochemicals, electricity, and energy. Their installation and maintenance directly affect the sealing, reliability, and service life of the valves. Here are the key points:1、 Installation points1. P...

The sealing effect of gate valves made of different materials mainly depends on the material characteristics of the sealing pair (valve seat and gate sealing surface), including temperature resistance, corrosion resistance, hardness, friction coefficient, and wear resistance. The following is a comp...

The sealing performance of manual gate valves directly affects their reliability under harsh working conditions such as high pressure, high temperature, corrosion, or granular media. In addition to conventional soft seals (such as rubber and PTFE) and hard seals (metal to metal), various special sea...
