Plug Valve Selection in Multiple Application Industries
JingGong Valve company about plug valve selection, should be based on its structural characteristics and design to achieve the function, and then combined with the use of what industry, so that you can better selection and use.
1. Used to distribute media and change the direction of media flow, its operating temperature is not higher than 300 ℃, nominal pressure PN ≤ 1.6MPa, nominal diameter is not greater than 300mm, it is recommended that the selection of multi-way plug valve.
2. Milk, juice, beer and other food businesses and pharmaceutical plants and other equipment and piping, it is recommended to use austenitic stainless steel, tightly set conical plug valve.
3. Oilfield mining, natural gas field mining, pipeline transmission of branch pipe, refining and cleaning equipment, nominal pressure level is not greater than Class300, nominal diameter is not greater than 300mm, it is recommended to use oil-sealed conical plug valve.
4. Oilfield mining, natural gas mining, pipeline transmission of branch pipe, refining and cleaning equipment, the nominal pressure level is not greater than Class7500, the nominal diameter is not greater than 900mm, the working temperature is not higher than 340 ℃, it is recommended to use oil-sealed conical plug valve.
5. In the large chemical industry, containing corrosive media in the pipeline and equipment, the requirements of opening or closing speed faster occasions, for nitric acid-based media can be selected PTFE sleeve sealed conical plug valve; for acetic acid-based media, Crl8Nil 2M02Ti stainless steel with PTFE sleeve sealed conical plug valve.
6. In the gas, natural gas, HVAC systems in the pipeline and equipment, nominal diameter is not greater than 200nm, it is appropriate to use packing type conical plug valve.
