Combination air release valve provide 3 functions:
1. Large air release
2. Small air release
3. Large air intake during draining of the pipeline.
Float Sterngth:
Features:
• All internal parts are 304SS material without rusting.
• Can blow off the water on top of the sealing arc thru small orifice and keep it dry to prevent polluted water coming into pipeline during vacuum.
