Specifications

Air vent valve 
1) Material for valve body :cast iron or ductile iron 
2) Working pressure:PN1.0--1.6MPa

  Single mouth air valve has the characteristics of removing gas in pipe, reducing resistance and saving energy. The capacity of the single mouth air valve is several times than common air valve. When pipe occurs negative pressure, the single mouth check valve can absorb air quickly and automatically avoid pipe from cracking. The material of the float ball is stainless steel

Performance parameters:
dium: water
2.temperature: room temperature
3.Shell strength test pressure: 1.5MPa, no damage.
4.Float seal test pressure: 0.05 ~ 1.1Mpa and leak-free.
5.Body material: gray cast iron HT200.
6.Float material: stainless steel.
