ARV-1-A - Automatic Air Release Valve
DN25
The ARV-1-A is a automatic air release valve. Its function 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 trapped air 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. This maintains a constant air gap between the sealing mechanism and the medium.
- Designed to efficiently extract air trapped in pipes, filters, tanks and other equipment which must work without the presence of air.
- The valve has one seal, which expels both kinetic and residual air automatically, and this function is not affected by water pressure.
- Continuous and automatic operation.
- Efficient in design; with minimal parts for ease of maintenance.
- Its exclusive Y-shaped discharge outlet design allows a much greater air flow than other valves of this type, in both the discharge and the intake phases.
- The valve seals at very low pressures.
- The valve is UV stable.
