Ensures discharge of great air mass during filling big floated pipelines     Allows in flows of large volumes of air when pipe is emptied     Release of air under pressure
Ventilation outlet in nominal size (large opening cross-section according to the flange size)
Two Staged closure Design
2-level Ventilation Design
Flange pursuant to EN 1092-2 (DN 50 can also be provided with 2" threaded connection)
Efficient, high performance ventilation protects pipeline from vacuum related damages
Discharge all air inside the pipeline while system is still operating
Small Volume/Weight Design
Impact-free closing
High volume air intake for vacuum break purposes, both during draining of water pipelines and/or column separations
Prevents pipeline bursts during pump trip & rapid pipeline filling
