QPARVX automatic exhaust valve

Structural features and uses

 

OPARVX automatic exhaust valve, in general, contains about 2VOL% of dissolved air in the water. During the water delivery process, the air is continuously released from the water and gathers at the high point of the pipeline to form an air bag (AIR POCKET). Making water delivery difficult, the system's water delivery capacity can be reduced by about 5-15%. The main function of this micro-exhaust valve is to eliminate this 2VOL% dissolved air and is suitable for installation in high-rise buildings. Pipes in the plant area, small pumping stations to protect or improve the system's water delivery efficiency and save energy.

The SIMPLE LEVER TYPE micro-exhaust valve is an elliptical valve body. All internal parts including float ball, lever and valve seat are 304 stainless steel. The internal exhaust standard is 1/6, suitable for use. Working pressure environment in PN16. Medium temperature: 0-80 ° C.

 

OPAVAX automatic exhaust valve is mainly used in HVAC systems, often installed at the commanding heights or elbows to eliminate excess gas in the pipeline, improve pipeline efficiency and reduce energy consumption.
