FVA-FVS Adjustable Flow Valves for Clean Gas and Air

Operating conditions encountered in the automatic controlling 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 amount of flow. With Hauck adjustable flow valves, the flow rate can be easily changed at any of the 10 or more adjusting points provided. Therefore, the valve flow curve can be characterized to suit different constants in pressure, flow suction, or discharge resistance occuring at the minimum, maximum or in-between capacities.
