• Continuous air release valve for wastewater
• Max. air release capacity: 440 m³/hr
• Max. opening size: 480 mm²
• Sealing seat is not in contact with the wastewater (air pocket) both connections enable efficient flushing during maintenance work (top connection = rinsing water ingress)

• Flange drilled PN 10 – DIN 2501 (PN 16 – DIN 2501 for DN 200 please specify when ordering)
• all mechanical parts are made of corrosion-resistant materials
• the continuous function enables the removal of large air quantities even under working pressure
• Please observe our operating and maintenance instructions.
• Maintenance: Air release valves must be checked and serviced regularly; this involves taking the valve out of operation and flushing via both connections.
• For the dimensioning of air release valves, please observe our technical information or the worksheet by the DVGW (German Association for Gas and Water) W 334.
