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...

The structural design of manual gate valves is centered on achieving reliable cutoff of medium flow. Its main components and structural characteristics are as follows, which can be analyzed in detail from three parts: core components, drive mechanism, and sealing system:1、 Core structural component...

The working pressure and temperature range of high-temperature and high-pressure gate valves need to be determined based on specific materials, structural design, and industry standards. The following are common ranges and explanations:1、 Range of work pressure1. Conventional pressure levelNational...

Compared with other valves, manual gate valves have the following advantages and disadvantages:advantageLow fluid resistance: When the manual gate valve is fully opened, the gate opening height is large, and the fluid can pass through the valve without obstruction. The flow channel is almost unobstr...

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...
