1600 Sewer Vent Valve
The 1600 Series Sewer Vent is cast from 356-T6 aluminum alloy for light weight construction. The valve is then powder coated a green epoxy that is highly resistant to sewer acids and gases. It is finished with a green coating that blends in nicely with the existing environment. A 1/4" x 1/4" protective mesh screen keeps debris and insects form entering the vent pipe while maintaining the required open area for municipal use ( 1.25:1 ratio ). Alternative materials are available upon request.

1700 Sewer Vent Check Valve
Cast in either 356-T6 aluminum alloy, or stainless steel, the 1700 Series allows for ventilation while in the open position. Our patented float design automatically seals off the vent pipe to prevent inflow of water into the lines. A stainless steel insect screen and flame screen keep debris from entering the vent pipe. All hardware is 316 stainless steel, and the valve body is powder coated with a special epoxy that is highly resistant to sewer gases and acids.

2000 Sewer Vertical Vent Check Valve
The Sewer 2000 Vertical Vent Check Valve is a dual-action float design. The top portion of the valve allows for ventilation in the open position, and prevents inflow of water during floods.
The bottom ball float blocks the out flow of water should the sewer line reach capacity. This is especially important in areas where sewer out-fall lines run next to rivers and streams. The overflow of sewer collection lines in these areas would be devastating to the quality of the water and surrounding land.

2100 Mushroom Check Valve
The 2100 Mushroom Check Valve mounts vertically with a 2" female thread connection. The body is molded from UV resistant reinforced nylon. The valve has a 1:1 ratio open area allowing for venting in the open position. A polyethylene float rises to a neoprene gasket to prevent inflow of water in flood conditions. Easily retrofitted. The 2100 is typically used to ventilate grinder pump wet wells.
