Cock of the pneumatic valve selection principle 2)

and plug structure and can be realized in the following principles mentioned functions of design rules:, distribution of medium and change the flow of the medium, and the working temperature ℃ or less, nominal pressure or less. MPa, nominally from the direction of the mm or less, multi-channel clogging the use of pneumatic valve is proposed. , milk, juice, beer and other food companies and pharmaceutical equipment and pipelines, advice on the use of austenitic stainless steel and close tapered plug pneumatic valve. , oil exploration, field development, pipeline, pipe flushing and cleaning equipment, pressure rated grade CL or less, by the name of the mm or less, working temperature ℃ or less and suggest using tapered plug pneumatic valve oil seal. , oil exploration, field development, pipeline, pipe flushing and cleaning equipment, pressure rated grade CL or less, by the name of the mm or less, working temperature ℃ or less and advice in the use of the cone pressure balance type pneumatic valve. , in a large chemical industry, pipeline and equipment of corrosive medium, need to open or close the occasion faster into nitrates media, to choose the teflon seal set CrNi stainless steel cone plug; For acetic acid media, on the basis of the PTFE casing CrNiMoTi choose sealed stainless steel cone plug pneumatic valve. , coal gas, natural gas, heating and ventilation system and pipeline, when the nominal pressure or less. MPa by mm or less, in the name of the conical cartridge should choose equipment. Keywords:
