Introduction to Butterfly Valve
1. Scope of application
It is widely used in gas pipelines and waterways of metallurgy, light industry, electric power, petrochemical systems, etc.
2. Specifications and models
Pressure range: PN1.0—4.0Mpa
Nominal diameter: DN15—500mm
3. Connection method
(1)Wafer butterfly valve
(2)Flange butterfly valve
(3)Lug butterfly valve
(4)Welded butterfly valve
4. Performance characteristics
(1)It is convenient and quick to open and close, labor-saving, low fluid resistance, and can be operated frequently.
(2)Simple structure, small size, short structure length, small size, light weight, suitable for large-caliber valves.
(3)Mud can be transported, with less liquid accumulated at the pipe mouth.
(4)Under low pressure, good sealing can be achieved.
(5)Good adjustment performance.
(6)When the valve seat channel is fully open, the effective flow area is larger and the fluid resistance is smaller.
(7)The opening and closing moment is small, because the discs on both sides of the rotating shaft are basically the same under the action of the medium, and the direction of the torque is opposite, so the opening and closing is more labor-saving.
(8)The sealing surface material is generally rubber or plastic, so the low-pressure sealing performance is good.
(9)Easy to install.
(10)The operation is flexible and labor-saving, manual, electric, pneumatic and hydraulic modes can be selected.
