[Adaptation]
According to the structural characteristics of the plug valve and the design can achieve the function, can be selected according to the following principles.
① for the distribution of media and change the direction of media flow, the working temperature is not higher than 300 ℃, nominal pressure PN ≤ 1.6MPa, nominal diameter of not more than 300mm, the proposed multi-channel plug valve.
② milk, fruit juice, beer and other food enterprises and pharmaceutical plants and other equipment and pipelines, the proposed selection of austenitic stainless steel, tight-type conical plug valve.
③ Oilfield mining, natural gas field mining, pipeline transportation branch, refining and cleaning equipment, the nominal pressure level is not greater than Class300, nominal diameter of not more than 300mm, the proposed selection of oil-sealed cone-shaped plug valve.
④ Oilfield mining, natural gas extraction, pipeline transportation branch, refining and cleaning equipment, the nominal pressure level is not greater than Class7500, nominal diameter of not more than 900mm, the working temperature is not higher than 340 ℃, the proposed selection of oil-sealed conical plug valve.
⑤ In the large chemical industry, corrosive media containing pipes and equipment, requiring open or close faster occasions, for nitric acid-based media can be used PTFE sealed sleeve conical plug valve; for the Acetic acid-based media, can choose Crl8Ni12Mo2Ti stainless steel inlaid PTFE sleeve sealed cone-shaped plug valve.
⑥ in the gas, natural gas, HVAC systems and equipment in the pipeline, the nominal diameter of not more than 200mm, should use filler-type conical plug valve.
