Description
APCO ASR Sewage Air Release Valves feature an elongated body that minimizes clogging and prevents sewage from fouling up the mechanism. The proven design with longer float stem reliably emits air from the pipeline, preventing erratic and unpredictable flows and high head loss due to formation of air pockets. Air in a pipeline increases system flow resistance and increases system head against which pumps must operate.
Because sewage media generates large quantities of gas, the potential for air entrapped with sewage pipelines is even greater than in water lines. It is recommended that each high point be protected with a Sewage Air Release Valve.
While it is impossible to totally prevent accumulation of air (or gases) within the piping system, the volume can be greatly minimized by installing APCO Air Release Valves on pipeline high points.
