The application of the pneumatic valve, pneumatic valve cover material temperature 5)

different body, for pneumatic valve cover material is as follows: the temperature of casting medium is an ℃ high temperature using pneumatic valve, cast iron pneumatic valve cover. Malleable iron body, medium temperature ℃ maximum use hat. Ductile iron pneumatic valve, pneumatic valve cover for ℃ high temperature medium. High silicon cast iron pneumatic valve, pneumatic valve cover for ℃ high temperature medium. Carbon steel pneumatic valve, pneumatic valve for ℃ ( Forging Mn steel, - Manganese can reach ℃) The highest use of medium temperature cover. CrMo steel pneumatic valve, pneumatic valve cover for ℃ high temperature medium. CrNiTi stainless steel and CrNiMoTi stainless steel pneumatic valve, pneumatic valve cover for ℃ high temperature medium. Copper alloy pneumatic valve, pneumatic valve medium for ℃ the highest working temperature. Titanium pneumatic valve, pneumatic valve medium temperature ℃ maximum use cover. Plastic pneumatic valve, pneumatic valve cover most medium temperature: nylon ℃ ℃ chlorinated polyether, and polyvinyl chloride (PVC) ℃, - 吗? ℃ polytrifluorochloroethylene, four fluorine - 吗? ℃. Different types of rubber diaphragm as rubber, natural rubber depends on ℃, nitrile rubber, neoprene ℃, fluorine rubber ℃. Pneumatic valve rubber, plastic, rubber, plastic lining, and heat resistance. Pneumatic valve, ceramic and glass metamorphic resistance difference is generally use below ℃. The limitation of heat resistance of enamel pneumatic valve, maximum over ℃ medium temperature sealing material. Keywords:
