air valve AVK Series 701/70

Air valve AVK Series 701/70
Main competitive advantages:

•   A large air gap between the liquid and the sealing system ensures reliable operation of the valve even with aggressive liquids and in the presence of solid impurities in the liquid.  
•   Cross-sectional area of exhaust holes: automatic - 12 mm², kinetic - 804 mm².
•   Boom spring of upper and lower floats prevents unnecessary operation of the automatic valve due to its compensation of low pressure fluctuations.
•   The conical body with a funnel-shaped lower part of the valve is designed for the maximum volume of air within the minimum length of the valve and prevents clogging due to the accumulation of solid impurities.
•   Body made of stainless steel or reinforced polyamide
•   Drainage or flushing with clean water from an external source is possible through a 1/4” drain tap.
