Single Orifice Air Release Valve Working Principle

At the beginning of the pump, a large diameter is used to remove a large amount of gas in the pipeline to improve the water efficiency of the pump; When the pipe is normally supplied with water, trace gases are discharged through holes in the piston rod to ensure the pipe is fully supplied.

Single Orifice Air Release Valve Installation and Commissioning

Install a gate valve in front of the valve for the next installation and maintenance. If the discharge valve is in the pipeline where the water is frequently cut off, it is recommended to install a buffer valve in front of the discharge valve. For specific use, please consult ZECO Valve Group.
