Features & Benefits

SA45 has low-pressure intake and exhaust and high-pressure micro exhaust functions with ordinary air valves. Its low-pressure intake and exhaust work when the pipeline pressure is low (such as filling the empty pipe with water, emptying the pipeline, etc.), mainly for a large amount of exhaust and intake under low-pressure conditions; High pressure micro exhaust is used to timely discharge the continuously evolving gas inside the pipeline during normal pressure operation, in order to reduce various adverse consequences that may occur. It also has a waterproof hammer function.
