Ball valve body generally choose what material?

Answer:

Ball valve body selection of materials:The maximum service temperature of 1Cr5Mo and alloy steel valves is 550 degrees centigradeThe maximum service temperature of 12Cr1MoVA and alloy steel valves is 570 degrees centigrade1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti stainless steel valves -196 ~ 600 DEG CCopper alloy valves -273 ~ 250

Ductile iron (suitable for water supply and drainage, small factories)Cast steel (suitable for water supply and drainage, small factories)All kinds of stainless steel (natural gas, chemical, metallurgical and other large factories and power plants.)Copper, marine, tap water, gasChoose what material, mainly depends on what you are used in the above, do not understand?! No, in general, only to determine their own level of demand!!!

Plastic valve (nylon) maximum use temperature of 100 degreesPlastic valves (chlorinated polyether), the highest use temperature of 100 degreesPlastic valve (PVC), the highest use temperature of 60 degreesPlastic valves (poly three CFC) -60 to 120 DEG CPlastic valves (PTFE) -180 ~ 150 DEG CPlastic valve (natural rubber diaphragm valve), the highest use temperature of 60 degreesPlastic valve (Ding Jing rubber, neoprene diaphragm valve), the highest use temperature of 80 degreesPlastic valve (fluorine rubber diaphragm valve), the highest use temperature of 200 degrees
