It is one-time injection molding, with the advantages of good sealing, small resistance, smooth inside and outside, acid and alkali corrosion resistance, anti weathering. Both ends of the air valve are equipped with socket, which is convenient to connect with the pipeline.The design of inclined blade makes the check valve more efficient.]]> PP air valve and air volume control valve are indispensable central air conditioning terminal accessories in the ventilation, air conditioning, and air purification engineering of industrial plants and civil buildings. They are generally used in air conditioning and ventilation system pipes to adjust the branch pipes’ air volume. It can also be used The mixed adjustment of fresh air and return air is used as a gas medium to adjust the flow or cut off the dust in the dusty cold air or hot air gas pipeline of the ventilation and environmental protection projects in the hardware, chemical, building materials, power station, glass, and other industries. According to the operation, it can be divided into manual damper and electric damper. pp windpipe

Performance characteristics of PP damper

The electric air valve is composed of the electric actuator and valve body. Electric butterfly valve usually consists of angular stroke electric actuator (0～90°partial rotation) and the butterfly valve as a whole through mechanical connection. The active mode is classified into the on-off type and regulating type, and the latter two are general. It is a straight thread electric actuator (0～100), and the valve body is mechanically connected with PP packing.
