Product Advantages
- Reliable operation reduces water hammer incidents.
- Dynamic design allows for high capacity air discharge whie preventing premature closing.
- Float and seal assembly are enclosed in a one-piece, easily replaceable unit – independent of the air vent body.
- Sealing assembly, with its unique patented rolling seal feature which allows gradual opening, closing and self-cleaning, is contained in the one-piece float assembly.
- Simple and reliable reinforced nylon body is compact in size and light-weight.
- The light-weight feature is ideal for installation on plastic piping systems and other light-weight piping systems.
- Threaded discharge outlet allows connection of additional piping for venting and drainage.
- Body and all operating parts made of high-strength corrosion-resistant composite materials.
Applications
- Pump stations – after the pump and after the check valve
- Downstream (after) and upstream (before) shut-off valves
- After deep well pumps
- On long, constant sloped pipeline segments
- At peaks along the pipeline and at peaks relative to hydraulic gradient
- At end lines
- Before water meters
- On strainers and filters
