Product Description

Product Description

     Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. Butterfly valves are popular in the industry because of their lightweight, fast operation, and low costs. These valves use handles, gears, or automatic actuators for operation as per the requirement.

Types of Butterfly Valves:
     As per Disc Closure Design: 1.Concentric Butterfly Valve; 2. Eccentric Butterfly Valve.
     As per Piping Connection Design: 1. Wafer Type Butterfly Valve; 2. Lug Type Butterfly Valve; 3. Double Flange Butterfly Valve.

Feature:
     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 the least accumulation of liquid 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.
