Integral Isolation Valve & Triple Function

DVD Air Valves with Integral Isolation Valve are designed to perform three functions:

1. Venting of large volumes of air on the start-up of the system, while pipelines are filled.

2. Intake of large volumes of air on shut-off of the system, which pipelines are being drained.

3. Discharge of pressurized air pockets during the operation.

In addition to these functions, the Air Valve has an Integral Isolation Valve, enabling isolation of the sealing parts for cleaning and maintenance.
