Dual Air Release Valves
The Air Release Valve Range
The Dual Air Release Valves have all been designed to function under the harsh conditions of mining and mineral processing, these valves all come with the Dual stamp of approval. All valves are manufactured and tested to ISO 5208. We pride ourselves in being the leader in the valve slurry industry.
What Makes the Air Release Valve Unique?
The Dual Vacuum Release and Vacuum Breaker’s function is to automatically exhaust large volumes of air from the system when it is being filled and also to allow air to re-enter the pipeline when being emptied. The Orifice size is generally the same size as the pipeline inlet.
What Pressure Can the Air Release Valves Take?
More Info
We have constructed valves that have been built to a working pressure of 10 Bar up to 160 Bar.
Valve Linings
More Info
The Air Release Valve housing can be epoxy coated or natural rubber lined. A range of elastomer grades are available for corrosive duties.
Flange Drilling
More Info
Dual can construct the valve to match any Face to Face required and any flange drilling. Please enquire with our sales team for more information.
