AVRX Combination Dual Orifice Air Release ValvePN16 flanged
Combination air valves perform the functions of an air/vacuum valve(exhaust large quantities of air on startup,admits air on shut-down) and air release valves (release air continuously during operation) to maintain system efficiency and prevent pipeline surges.Able to release air at high flow rates.No shut off due to negative pressure caused by high-speed airflow.No airtight phenomenon: minimum air pressure doesn’t limit valves.High velocity air release close to sonic speed.The automatic air release function releases accumulated air from the system while it is under pressure.
