When selecting manual electric gate valves and their parameters, the following key factors need to be considered:
Medium type: Select appropriate materials and seals based on factors such as the type, temperature, pressure, and corrosion characteristics of the fluid inside the pipeline. For example, for corrosive media
Choose stainless steel or special alloy materials; For high-temperature media, high-temperature resistant materials should be used.
Power supply voltage: Electric gate valves rely on power sources, usually including direct current, alternating current, and pneumatic power forms. When selecting a power source, consideration should be given to the coordination of the control system
And the reliability and stability of the power supply.
Control mode: Electric gate valves can be controlled manually, electrically, or remotely as needed. The appropriate control method should be selected based on the specific usage situation. For example, in
In flammable and explosive environments, explosion-proof motors should be selected.
Size and connection method: The size and connection method of electric gate valves should be selected according to the requirements of the pipeline system. Common connection methods include flange connection, threaded connection, and
Welding connections, etc.
The characteristics of valves include opening and closing time, regulating performance, and flow characteristics. The selection of appropriate valve characteristics should be determined based on specific usage scenarios.
Drive mode: There are various drive modes for electric gate valves, such as ordinary motor drive and explosion-proof motor drive. Suitable drivers can be selected based on the on-site environment and safety requirements
Method.
Certification and Standards: Ensure that the selected electric gate valve complies with relevant international and national standards, such as ISO, API, etc. At the same time, check the certification information of the product, such as CE, UL
Wait to ensure its quality and safety.
Maintenance and lifespan: Products that are easy to maintain and have a longer service life should be selected. Understand the after-sales service and technical support provided by the manufacturer to ensure that it can be used during the process
Get timely help.
