Check Valves Factory introduces the selection basis of valves:


1. The purpose of the selected valve, the operating conditions and the control method.
2. The nature of the working medium: working pressure, working temperature, corrosive properties, whether it contains solid particles, whether the medium is toxic, whether it is a flammable or explosive medium, the viscosity of the medium, etc.
3. Requirements for valve fluid characteristics: flow resistance, discharge capacity, flow characteristics, sealing level, etc.
4. Installation size and external size requirements: nominal diameter, connection method and connection size with the pipeline, external size or weight limit, etc.
5. Additional requirements for valve product reliability, service life and explosion-proof performance of electric devices. (Note when selecting parameters: If the valve is to be used for control purposes, the following additional parameters must be determined: method of operation, maximum and minimum flow requirements, pressure drop for normal flow, pressure drop at closing, maximum and minimum inlet to the valve pressure.)

Through the above introduction, Hydraulic Ball Valves Exporter hopes that you can simply refer to the content of this article in future use.
