Central Heating Air Release Valve For Fire Sprinkler System Deep Well
Air Release Valve Description:
| The air release valves will be installed at sections of the pipeline where air pockets would be formed. |
The valves shall be of robust construction of double orifices with an integral isolating valve and |
| flanged base for connection to a valve stem that connects the air valve to the main pipeline. |
| The bore leading to the flange base shall be in accordance to the size of the main pipeline and the expected accumulation of air. |
