QB2 Double Row Air Realese Valve


Double row exhaust valve, also known as a double row  valve. Is suitable for industrial media for water lines, as a rapid removal of gas equipment in the pipeline. It is also a necessary equipment to improve the efficiency of water delivery equipment and protect the pipe from deformation and rupture.


This valve is suitable for industrial medium for water pipeline, as a rapid removal of gas equipment in the pipeline, to improve the efficiency of water delivery equipment and protect the pipe from deformation and rupture, is the pipe required equipment valve for the cylinder-shaped valve body, the internal main stainless steel float and plug valve installed At the outlet of the pump or in the distribution line, it is used to remove a large amount of the assembled air from the pipe to improve the efficiency of the use of the pipe and the pump, and when negative pressure occurs in the pipe, the valve can also quickly draw in air to prevent damage to the pipeline due to negative pressure.
