Butterfly valve selection points

1. The main control parameters of the butterfly valve are the specifications.

2. The butterfly valve is a single-plate type damper, which has the advantages of simple structure, convenient processing, low cost and simple operation, but the adjustment precision is poor, and it is only suitable for the occasion of switching or coarse adjustment in the ventilation and air-conditioning system.

3, can be manual, electric or zipper operation, can be fixed at any angle of 90 ° range.

4, due to the single-axis single-valve plate, the bearing capacity is limited, the valve life is short under large pressure difference, large flow rate conditions. The valve is divided into a closed type and a normal type, and is insulated and non-insulated.

5. The electric butterfly valve has only two-position control, and the electric actuator is the same as the multi-leaf valve.
