The Hauck AFV Adjustable Flow Valves are designed to permit easy modification of flow rates at any of the 10 or more adjusting points provided in the valve. The gas or air flow curves can be characterized to suit specific operating requirements from the minimum to the maximum flow rate. These valves are suitable for use with air or any clean industrial fuel gas. Operating conditions encountered in the automatic control of gas and air flows often require valves with an adjustable flow curve which can be altered at various points of opening to obtain the desired flow rate. Such flexibility is not possible with ordinary adjustable port valves that has a fixed height of the port opening over the entire range of operation. Hauck AFV valves allow flow characteristics to be controlled with greater flexibility. These valves are designed for use as control valves and cannot be used as shutoff valves.
