Kinetic Double (H-42k) Air Valve
Share to:
Principle: Air Valves are Regularly used to provide for the following requirements in water mains-
To release air when the main is being filled and to close and remain closed when the pipes is full to prevent loss of water. To open and admit air while the main is being emptied. To release air accumulated under pressure during normal working conditions in the pipe.
Again without loss of water in kinetic air valves, this operation is effected automatically by means of a ball float working in conjunction with an orifice appropriate type for the duty.
Marck kinetic Air Valves are a combination of a small orifice and a large orifice Air Valve. A Separate conventional isolating sluice Valve non-rising type with/without bevel gear arrangement is provided for inspection/maintenance of the Air Valve without closing the main line.
Small orifice single Air Valves, Screwed or Flanged with or without isolating stop the cook to release air at or below the maximum working pressure.
