ARV-3 - 316 Stainless Steel Sewer Air Release Valve
The ARV-3 incorporates a kinetic and an automatic air release valve in one single valve body. Its function in the sewage system is to allow air to be expelled from the pipeline during filling, and air to be admitted into the pipeline during emptying.
Applications:
When the pipeline is being filled, trapped air is released through the large orifice of the kinetic valve. During emptying of the pipeline, the valve allows air to enter the pipeline through the large orifice. During normal operation the large orifice remains closed while the small orifice allows small amounts of entrapped air which has accumulated, to be released through the valve.
The valve mechanism is designed to absorb small changes in pressure which prevents the small orifice from continually opening, thus maintaining a constant air gap between the sealing mechanism and the sewage.
- All wetted components manufactured from 316 and 316L stainless steel and UV stabilised plastic, makes it totally non-corrosive.
- Triple action air release in the one unit; incorporates both automatic and kinetic air release and vacuum breaking functions.
- Design of valve maintains air gap between fluid and sealing mechanism.
- Lower shape of valve body is designed to provide ease of drainage of debris back into the pipeline.
- Protects wastewater / water systems from suffering structural damage caused by hammer and vacuum situations.
- Inherently reliable with low maintenance requirements due to the valve design and selected materials.
- The lightweight valve is designed to provide complete separation of the sewage from the sealing mechanism, utilising non-corrosive components and materials.
