Key points for product selection
1.The main control parameters of butterfly valve are specifications and dimensions.

2. The butterfly valve is a single-plate air valve. It has a simple structure, easy processing, low cost, and easy operation. However, the adjustment accuracy is poor. It is only suitable for switching or rough adjustment in ventilation and air-conditioning systems.

3.Can be operated by manual, electric or zipper typecan be fixed at any angle within 90° range.

4. Due to the limited bearing capacity of a single-axis single valve plate, the service life of the valve is short under the conditions of large pressure difference and large flow rate. The valve can be divided into closed type and ordinary type, and can be divided into insulation and non-insulation.

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