Vent-Tech Valve Series Configurations
SERIES-C Combination Air Valves
Note to Engineer
Shall be four (4) function valves designed to:
- Exhaust large quantities of air at start-up during the filling of a pipeline system.
- Prevent the development of hydraulic transients (surge control) during start-up and pressure surges and shall operate automatically.
- Release accumulated air in a pipeline system while the system is operational and under pressure.
- Open and admit large quantities of air into the pipeline system during draining or if negative pipeline pressure occurs.
SERIES-B Biased Combination Air Valves
Note to Engineer
Shall be four (4) function valves designed to:
- Exhaust controlled quantities of air at start-up during the filling of a pipeline system.
