The following factors must be considered when choosing a gate valve:

Working pressure and working temperature: according to the specific working situation to determine the working pressure and operating temperature range, to choose the suitable material and specifications.
Media use: different media to choose different gate valve requirements. For example, for corrosive media, it is necessary to choose an acid-resistant and alkali-resistant material; for high-temperature environments, it is necessary to select a high-temperature gate valve.
Flow requirements: according to the need to control the size flow of the corresponding gate valve model and specifications.
Driving mode: manual, conical, electric and other driving modes are selected according to working conditions and caliber.
Connection method: The gate valve connection method has many options, such as wire neck, flange, groove and quick installation, which should be selected according to the actual situation.
