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.

Advantages
Hauck Butterfly Valves utilize maximum port openings for high flow rates. An easily read dial plate helps the operator maintain settings from burner to burner. Settings can be duplicated allowing quick return to previous flow rates.
The BVA is available for automatic or manual control. The manual valve, 100 series, is equipped with a short control lever and a thumb screw to easily set and lock valve position. The automatic series valves come with tapped and threaded bolt locations for the addition of a control motor.
BVA valves are NPT threaded in the 1″ to 6″ sizes. In addition, there are 6″, 8″, and 10″ flanged valves with RPM flanges. The 1000 series is a manual valve, while the 2000 series is an automatic valve.
BVA 100 and 400 series are constructed of a cast iron body with a steel valve disc, brass shaft and viton shaft seals.
BVA-H 100 and 400 series are constructed of a cast iron body, stainless steel valve disc and stainless steel shaft. A zinc plated steel retaining nut and packing ensure a high temperature shaft seal.
BVA 1000 and 2000 flanged series are constructed of a welded steel body, steel valve disc and brass shaft.
Hauck Manufacturing can provide a bracket and linkage for the BVA to be used with most any control motor or actuator.
Wafer butterfly valves from 6″ to 22″ are available.
