3. Features:

Butterfly valve is simple in structure, small in size, light in weight, and consists of only a few parts.
And only need to rotate 90° to quickly open and close, the operation is simple, and the electric valve has good fluid control characteristics.
When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance
When the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.
Butterfly valves have two types of seal: bullet seal and metal seal.
Elastomeric sealing valve, the sealing ring can be mounted on the valve body or attached to the periphery of the disc.
Valve with metal seal generally has a longer life than the valve with elastic seal, but it is difficult to achieve complete seal.
Metal seals can adapt to higher operating temperatures, while elastic seals have temperature-limited defects.
