Qb2 flange double port exhaust valve

Short Description:

Qb2 flange double port exhaust valve is applicable to the pipeline with water as the working medium. It is used as the equipment for removing gas in the pipeline, so as to improve the efficiency of the water conveying equipment and protect the normal operation of the pipeline. In case of power failure, there will be pressure in the pipe when the pump is stopped, which will cause pipeline vibration or rupture. The exhaust valve will inhale with time to ensure the safety of the pipeline. The double port exhaust valve is widely used in municipal construction, irrigation and water conservancy, thermal power generation, petrochemical, metallurgy and mining, fire protection, food, shipping, medicine, textile and other fields.
