Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

MINOTAUR series replaceable seat high performance butterfly valve
(2) Single eccentric sealing coal valve
(3) Double eccentric sealing butterfly valve
(4) Triple offset sealing valve
2. Classified by sealing surface material
(1) Soft sealing butterfly valve.
1) The sealing pair is made of a non-metallic soft material to a non-metallic soft material.
2) The sealing pair is made of a metal hard material to a non-metallic soft material.
(2) Metal hard seal butterfly valve. The sealing pair is composed of a metal hard material and a metal hard material.
3. Classified by seal
(1) Forced sealing butterfly valve
1) Elastic sealing butterfly valve. The sealing specific pressure is generated by the valve plate pressing the valve seat when the valve is closed, and the valve seat or the valve plate is elasticized.
2) External torque sealing butterfly valve. The seal specific pressure is generated by the torque applied to the valve shaft
(2) Pressure sealing butterfly valve. The sealing specific pressure is generated by the pressure of the elastic sealing element on the valve seat or the valve plate.
(3) Automatic sealing butterfly valve. The seal specific pressure is automatically generated by the medium pressure.
4. Classified by work pressure
(1) Vacuum butterfly valve. The butterfly valve whose working pressure is lower than the standard atmosphere of the stack.
(2) Low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.
(3) Medium pressure butterfly valve. The nominal pressure PN is a butterfly valve of 2.5--6.4 MPa.
(4) High pressure disc valve. The nominal pressure PN is a butterfly valve of 10. 0--80.0 MPa.
(5) Ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.
5. Classified by operating temperature
(1) High temperature butterfly valve. t>450 C butterfly valve
(2) Medium temperature disc valve. 120 C
(3) Normal temperature butterfly valve. a 40C
(4) Low temperature butterfly valve. A butterfly valve of 100
(E) Ultra-low temperature butterfly valve. t<一100 C butterfly valve
6. Classified by connection
(1) Wafer type butterfly valve.
(2) Flanged butterfly valve.
(3) Ear type butterfly valve.
(4) Welded butterfly valve
