Cock of the selection principles outlined

according to structural features and plug valves designed to function can be achieved, the proposed use by the following principles:
1, for the cool schoolbags media and change the flow direction, start working temperature ≤ 300 ℃, nominal pressure ≤ 1.6MPa, nominal by ≤ 300mm, suggested the use of multi-channel plug valves.
2, milk, juice, beer and other food companies and pharmaceutical equipment and piping, etc., suggested the renault megane car gps dvd of austenitic stainless steel to close-set conical plug valves.
3, oil exploration, gas field development, pipeline transportation of the branch pipe, refining and cleaning equipment, the nominal pressure level ≤ CL300, nominal by ≤ 300mm, temperature ≤ 340 ℃, suggested the use of oil seal conical plug valves.
4, oil exploration, gas led rental screens development, pipeline transportation of the branch pipe, refining and cleaning equipment, the nominal pressure level ≤ CL2500, nominal by ≤ 900mm, temperature ≤ 340 ℃, suggested the use of pressure balanced inverted conical plug valves.
5, in a large chemical industry, containing corrosive medium on the pipes and equipment, requiring faster turn on or off the RoHs driver for led screen, that the base for the media, the choice of stainless steel PTFE 1Cr18Ni9 conical plug sealing sleeve vinyl fluoride; for the acetate-based media, can be used Cr18Ni12Mo2Ti stainless steel PTFE sealing sleeve conical plug valves.
6, the gas, natural gas, HVAC systems and equipment in the pipeline, when the nominal pressure ≤ 1.0MPa, led light power supply by ≤ 200mm, should use filler-type conical plug valves.
