VAG | Spring-Loaded Air Valve
- Spring-loaded air valve with very high venting capacity for rapid discharge of the medium present in the pipeline, for air release when filling the pipeline and during operation. Large cross-section for venting large amounts of air during fast switch-off procedures, rapid discharge or pipe bursts. Used in bottom outlets, barrages or dams, long-distance pipelines or downstream of large butterfly valves. The integrated friction damper reduces the speed of the closing movement and thus pressure surges.
- Sealing system/standard: Resilient seated
- Spring-loaded air valve
- Venting function:
- Large cross-section to vent high quantities of air for pipe collapsing protection
- Small orifice to release low quantities of air during operation under pressure
- Medium orifice to release when filling the pipeline

- With flange end acc. to EN 1092-2
- Minimum operation pressure: 0.3 bar

I took a gamble on this sweater, amazon clothing seems to sometimes be way different quality than what’s pictured but I was very happy when I received this sweater!

his sweater is a bulky, fairly heavy winter sweater that will be awesome for the office or casual wear. The fabric is very silky soft. It’s nice and snuggly! I can’t wait for it to get cool enough to wear it!
