2. Specification:

3. Features:

• Easy to open and close, labor-saving, fluid resistance is small, can be often operated.
• Simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valves.
• Can transport mud, the least liquid in the pipe mouth.
• Low pressure, can achieve a good seal.
• Good adjustment performance.
• When fully opened, the effective flow area of the valve seat channel is large and the fluid resistance is small.
• The opening and closing torque is small, because the butterfly plate on both sides of the rotating shaft is basically equal to the effect of the medium, Sealing surface material is generally used rubber, plastic, so the low pressure sealing performance is good.
• Easy to install.
• Operation is flexible and labor-saving, manual, electric, pneumatic, hydraulic mode can be selected.
