Butterfly valve structure advantages

Butterfly valve is easy to open and close quickly, labor saving, small fluid resistance, can often operate; Simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve; Can transport mud, at the mouth of the least liquid accumulation; Good sealing can be achieved under low pressure. Good regulating performance; When fully open, the effective flow area of the valve seat channel is large and the flow resistance is small.

Opening and closing torque is small, because both sides of the shaft valve plate under the action of the medium is basically equal, and the direction of the torque is opposite, so opening and closing is more labor-saving. Sealing surface materials are generally rubber, plastic, so better sealing performance; Easy installation;Flexible and labor-saving operation, can choose manual, electric, pneumatic, hydraulic mode.
