Plug valve selection principle

According to the structural characteristics of the plug valve and the function that can be achieved in the design, it is recommended to use the following principles:
1. It is used to distribute medium and change the flow direction of medium. The starting working temperature is ≤300°C, the nominal pressure is ≤1.6MPa, and the nominal passing time is ≤300mm. It is recommended to use multi-channel plug valve.
2. For equipment and pipelines such as milk, juice, beer and other food enterprises and pharmaceutical factories, it is recommended to use austenitic stainless steel ground tight conical plug valve.
3. In oil field mining, natural gas field mining, pipe branching, refining and cleaning equipment, the nominal pressure level ≤ CL300, the nominal pass ≤ 300mm, the working temperature ≤ 340 ° C, it is recommended to use oil-sealed conical plug valve.
4. In oil field mining, natural gas field mining, pipe branching, refining and cleaning equipment, the nominal pressure level ≤ CL2500, the nominal pass ≤ 900mm, the working temperature ≤ 340 °C, it is recommended to use a pressure balanced inverted cone plug valve.
5. In large chemical industry, pipelines and equipment containing corrosive media require high opening or closing speed. For nitric acid-based media, PTFE sleeves made of 1Cr18Ni9 stainless steel can be used. Conical plug valve; for acetic acid-based media, a Teflon plug with a Teflon sleeve made of Cr18Ni12Mo2Ti stainless steel is available.
6. In the pipelines and equipment of gas, natural gas and HVAC systems, when the nominal pressure is ≤1.0MPa and the nominal passage is ≤200mm, the filler-type conical plug valve should be used.
