Key Points For Product Selection Of Butterfly Valves

1. The main control parameters of butterfly valves are specifications and dimensions.

2. The butterfly valve is a single plate air valve with a simple structure, convenient processing, low cost, and easy operation. However, its adjustment accuracy is poor, and it is only suitable for use as a switch or rough adjustment in ventilation and air conditioning systems.

3. It can be operated manually, electrically, or with a zipper, and can be fixed at any angle within a 90 degree range.

4. Due to the limited load-bearing capacity of the single axis and single valve plate, the service life of the valve is short under conditions of large pressure difference and high flow rate. This valve can be divided into sealed and ordinary types, as well as insulated and non insulated types.

5. Electric butterfly valves only have dual position control, and the electric actuator is the same as multi leaf valves.
