Sanitary Stainless Steel Air Blow Check Valve
QILI's Sanitary Air Blow Check Valves are 'plug-style', where air pressure pushes the bonded rubber plug away from the seat. In the absence of air pressure, the spring returns the plug and holds it closed against the seat.
For 3A applications the  Air Blow Check Valve must be used with the incorporated filter disc and suitable air to be in contact with product.
Air usage: estimated air volume usage will depend upon the pipeline vessel to be evacuated. Applications:
Evacuation of process pipelines for product recovery and/or drainage
Air agitation of product in pipelines, tanks, and other equipment
Air drying of process lines and equipment for corrosion resistance/ formation of protective oxide films
