Applications
Classifications
1. Classification according to structural form
(1) Center seal butterfly valve
(2) Single eccentric sealed coal valve
(3)Double eccentric seal butterfly valve
(4) Triple eccentric seal valve
2. Classification according to sealing surface material
(1) Soft seal butterfly valve.
1) The sealing pair is composed of non-metal soft material to non-metal soft material.
2) The sealing pair is composed of metal materials and non-metal soft materials.
(2) Metal seal butterfly valve. The sealing pair is composed of metal hard material to metal hard material.
3. Classification according to sealing form
(1) Forced sealing butterfly valve
1) Elastic sealing butterfly valve. The sealing specific pressure is generated by the valve plate extruding the valve seat when the valve is closed, and the elasticity of the valve seat or valve plate.
2) External torque sealing butterfly valve. The sealing specific pressure is generated by the torque applied to the valve shaft.
(2) Pressurized sealed butterfly valve. The sealing specific pressure is generated by the charging of elastic sealing elements on the valve seat or valve plate.
(3) Automatic sealing butterfly valve. The sealing specific pressure is automatically generated by the medium pressure.
4. Classification according to work pressure
(1) Vacuum butterfly valve. Butterfly valve whose working pressure is lower than the standard reactor atmospheric pressure.
(2) Low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.
(3) Medium pressure butterfly valve. Butterfly valve with nominal pressure PN of 2.5--6.4MPa.
(4) High-pressure butterfly valve. Butterfly valve with nominal pressure PN of 10.0--80.0MPa.
(5) Ultra-high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.
5. Classification according to working temperature
(1) High temperature butterfly valve. Butterfly valve with t>450 C
(2) Medium temperature butterfly valve. 120 C
(3) Normal temperature butterfly valve. A 40C
(4) Low temperature butterfly valve. A 100
(5) Ultra-low temperature butterfly valve. t<-100 C butterfly valve
6. Classification by connection method
(1) Wafer butterfly valve
(2)Flange butterfly valve
(3)Lug type butterfly valve
(4) Welded butterfly valve
