5).Super high pressure valve-nominal pressure valve of PN is greater than 100 Mpa.
2.According to the medium temperature
1).High temperature valve - more than 450 'C.
2).Medium temperature valve -120'C≤t≤450'C
3).Room temperature valve - 40'C≤t≤120 'C
4).Cryogenic valve - 100'C≤t≤-40 'C
5).Super Cryogenic valves - less than -100 'C.
3. According to the valve body material
1).Metallic materials - such as carbon steel valves, cast steel valve, stainless steel, alloy steel, cast iron valve, the titanium alloy valve and monel alloy, copper alloy, aluminum alloy valve , lead alloy.
2).Metal body lining valves - such as fluoroplastics lining valve ,rubber lining valves, valve lining, lead lined valves, valve lining enamel valve.
3).Nonmetallic material valve - such as ceramics, plastics, glass fiber reinforced plastic valve.
4.According to the manipulation method
1).Manual valves-The hand wheel, handle, lever, sprocket, gear, worm gear, etc.,by the human in order to control the valve.
2).Electric valves-with the power to manipulate the valve.
3).Pneumatic valve-Use compressed air to control the valve.
4).Hydraulic valve-With the aid of liquids such as water, oil, transmission of external forces to manipulate the valve. These are classificaitons of valves description, hoping to help to you.
