ARV-5 - Air Release Valve for Waste Water & Fresh Water Systems
The ARV-5 incorporates a kinetic and an automatic air release valve in one single valve body. Its function in the waste water and fresh water system is to allow air to be expelled from the pipeline.
Applications:
When the pipeline is being filled, trapped air is released through the large orifice of the kinetic valve. 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 water.
- The ARV-5 valve is manufactured with certified materials, utilising certified welding techniques.
- All wetted components manufactured from 316 and 316L stainless steel and UV stabilised plastic, makes it totally non-corrosive.
- Double action air release in the one unit; incorporates both automatic and kinetic air release.
- Design of valve maintains air gap between fluid and sealing mechanism.
- Protects wastewater/water systems from suffering structural damage caused by hammer.
- Inherently reliable with low maintenance requirements due to the valve design and selected materials.
- The 50mm BSP incorporated into the top cover allows an extension to be added to vent the air higher into the atmosphere.
- The 6mm coupling on the cover allows condensation to drain from the valve.
- The lightweight valve is designed to provide complete separation of the sewage from the sealing mechanism, utilising non-corrosive components and materials.
