As a Butterfly Valve Leading Manufacturer, share with you.

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

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

3. It can be operated manually, electrically or by zipper, and can be fixed at any angle within 90°.

4. Due to the single-axis 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 large flow rate. The valve is divided into closed type and ordinary type, heat preservation and non-heat preservation.

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

Installation matters

The butterfly valve is simple in structure, small in size, light in weight, and its components are relatively small. A few key parts can constitute a butterfly valve. It is also very convenient to open. You only need to select the switch to ninety degrees. The fluid control is very good, you can increase or decrease the flow at any time, the valve has a certain resistance when transporting any fluid, and the resistance of the butterfly valve mainly comes from itself, such as the thickness of the butterfly valve body, if you want to reduce the fluid The resistance only needs to reduce its thickness.

Elastic seal has the defect of being limited by temperature.

The application range of the butterfly valve is also relatively wide. If it is used to control the flow, it is necessary to select different types and valve body sizes, because the butterfly valve itself is more suitable for some larger diameter valves when designing. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also used in cooling water systems of thermal power stations.
