Hole Standard Ductile Iron Double Ball Air Valveused in the highest point of pipeline or where is air closed for central air-condition (make cold and heat), to exclude sewage pipe gas to clear the pipeline, but when pipeline in normal operation, internal of pipeline the medium of water containing 2 VOL of the chemical composition of natural gas will be produced. This gas will be enlarge slowly, that’s big effect for pipeline, it will happen air-close or turnoff, now the exhaust valve will exclude air on time, to enhance efficiency of pipeline cold and heat supply, can save energy, it’s the necessary products for central air-condition. Product using lift more than 5 years. Guarantee term of usage is 12 months.
