D-060NS | Combination Air Valve
The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.
Working pressure range:
- D-060 NS, D-060-C NS – 0.2-16 BAR.
- D-062 NS – 0.2-25 BAR.
- D-065 NS – 0.2-40 BAR.
- Maximum operating temperature: 60°C.
- Maximum intermittent temperature: 90° C.
- Installation at the points of water pipelines where water column separation occurs, on peaks with steep slopes, and at points where anticipated conditions of surge and water hammer can occur.
