Free Floating Lever Air/Gas Vents 1-AV, 2-AV, 3-AV and 6-AV– Cast Iron
Description
Armstrong free floating lever Air/Gas Vents use the same bodies, caps, lever mechanisms, valves and seats of Armstrong inverted bucket steam traps that have been proven in years of service.
Elliptical floats and high leverage make it possible to open large orifices to provide adequate capacity for vent size and weight. The hemispherical valve, seat and leverage are identical in design, materials and workmanship to those for saturated steam service up to 69 bar, with the exception of the addition of a guidepost to assure a positive, leaktight valve closing under all conditions.
For Pressures to 21 bar or Specific Gravity Down to 0,40
1-AV – A cast iron air vent that uses a positive-closing free floating lever to ensure leaktight closing under all conditions. This vent is good for low capacity air/gas venting up to 21 bar.
2-AV, 3-AV and 6-AV – Cast iron vents using the same proven free floating lever mechanisms used in Armstrong steam traps. For applications where high air/gas venting capacity is required up to 17 bar.
