Some simple and inexpensive solutions EPG can provide include:
Air Release Valves -
These have a float and linkage mechanism that senses and releases air under pressure but it is usually limited to the amount of air it can admit and exhaust.
Air/Vacuum Valves -
These exhaust air during pipeline filling/start-up via a float that rises with liquid level. In addition, if a pressure loss or vacuum condition occurs, the float will drop and air will be admitted into the pipeline.
Combination Air Valves -
These combine the function of both the Air Release and the Air/Vacuum valve. We recommend using this air valve because it contains an air release orifice and a vacuum port in one assembly and, unlike the other valves; it can be used at high points and at any point in the pipeline system, providing added air release and protection.
