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.

BVA Butterfly Valves

Hauck butterfly valves control the flow of low pressure combustion air or fuel gas to burner systems. Two versions of the valve are available; the BVA series for ambient air service and most fuel gases; and the BVA-H series for preheated air applications up to 800°F (425°C). Each valve series is available in manual or automatic control mode of operation. BVA valves are ideal for individual burner or zone control and can be used as a trim valve to balance individual burners.

Product Image - MOV Self-Cleaning Micro Oil Valves

MOV Self-Cleaning Micro Oil Valves

Hauck's Self-Cleaning Micro Oil Valves provide accurate, reproducible and linear flow control of oil to any type of industrial process. As the valve flow indicator is moved, the action of the cleaning pin clears foreign obstructions from the crescent-shaped V groove of the valve disk. This feature ensures thorough cleaning of the controlling orifice without the need to dismantle the valve. Unlike conventional valves, there is no constricted flow orifice to cause valve clogging or burner flame fading.

WBV-H Wafer Butterfly Valves - Hot Air

Hauck Wafer Butterfly Valves are used to trim or control ambient or preheated air. The valve can be ordered with a hand lever or can be supplied with a lever and linkage for automatic control. When sizing wafer butterfly valves for automatic control, normal practice is to size for a valve differential pressure (Δp) of 10-20% of total available air pressure. When ordering, specify temperature service desired: ambient air to 400°F, or preheated air to1200°F.

Valves should be selected for maximum flow at no more than 70° open. Full ported wafer valves installed in lines of the same size offer increased flow for a fixed pressure drop up to 70° open. At greater openings, flow does not increase appreciably although ...
