(2) the blade of the volume control valve is open and open, and is used as a regulating valve in ventilation, air conditioning and air purification systems.

  

(3) through the test, the air volume control valve has good tightness, the relative air leakage is about 5%, and the regulating performance is good.

  

Two. Structural characteristics of air volume control valve

  

(L) the volume control valve has four specifications in the width of the blade, the blade shape is a diamond double leaf, and the blade is soft lapped, so the sealing performance is good.
