Key Points For Selecting Butterfly Valves

1. The main control parameters of the butterfly valve are the specifications and sizes.
2. The butterfly valve is a single-plate air valve, which has simple structure, convenient processing, low cost, and easy operation, but its adjustment accuracy is poor. It is only suitable for switching or coarse adjustment in ventilation and air conditioning systems.
3. It can be operated manually, electrically or by zipper, and can be fixed at any angle in the range of 90°.
4. Due to the single shaft and single valve plate, the bearing capacity is limited, and the service life of the valve is short under the conditions of large pressure difference and high flow rate. The valve is divided into closed type and ordinary type, heat preservation and non heat preservation.
5. The electric butterfly valve only has two-position control, and the electric actuator is the same as the multi-leaf valve.
