How to choose a valve

Thread Content

【My Environmental Protection Network】1. Choose the type of valve based on the usage requirements (for applications that require opening and closing, gate valves or ball valves can be selected)； For switching and regulation, choose a butterfly valve ； Check valves and foot valves that automatically prevent backflow of the medium in pipes ； A pressure reducing valve that automatically lowers the pressure of the medium inside pipes and equipment. ） ； 2. The pressure class of the valve is selected based on the type of medium (PN10, PN16, PN25, PN40, PN64……) ； 3. The valve diameter DN is the nominal diameter, referring to the inner diameter of the pipeline ； 4. Temperature range: The operating temperature of the medium determines the type of valve sealing; selecting the appropriate temperature rating can extend the valve’s service life ； 5. The material of the valve is selected based on the properties of the medium; factors such as corrosivity determine the appropriate material for the valve ； 6. Control mode: manual, pneumatic, or electric. Reposted from: [My Environmental Protection Network]
