Description
GeoFlow Air Vent & Vacuum Relief Valve — Model APVBK-1
The GeoFlow Air Vent & Vacuum Relief Valve is designed to protect your piping system from the damaging effects of trapped air and vacuum conditions. During system fill-up or operation, this valve automatically releases accumulated air that can cause airlock, reduced flow, and inefficient system performance. During shutdown or drain-down, it opens to relieve vacuum conditions, helping prevent pipe collapse or damage caused by negative pressure.
This dual-function protection makes the APVBK-1 a valuable addition to geothermal loop systems, irrigation mainlines, and other closed or semi-closed piping systems where trapped air and vacuum conditions are common operational concerns.
Key Features:
- Automatic air release — clears trapped air during fill-up and normal operation
- Vacuum relief function — protects piping from negative pressure during drain-down or shutdown
- Prevents airlock — supports consistent flow and system efficiency
- Protects pipe integrity — reduces risk of damage from pressure extremes
- Low-maintenance operation — automatic function requires minimal operator intervention
Common Applications:
- Geothermal loop system air management
- Irrigation mainline air and vacuum protection
- Closed-loop piping systems prone to air accumulation
- Systems requiring protection during fill, drain, or shutdown cycles
