BVA models are no longer sold - the BVG replaces all BVA parts. BVG valves are rated for both gas and air.

Description

The butterfly valves BVG, BVH, BVHM and BVHS are designed to adjust volumes of gas, cold and hot air, and flue gas on various appliances and flue gas lines. They are designed for control ratios up to 1:10, and with the mounted actuator IC 20 or IC 40 they are suitable for regulating flow rates for modulating or stage-controlled combustion processes.

Flow rates can be set and fixed using a lever, for example to limit the high-fire rate on the burner. A scale indicates the set angle of opening.

The BVG is a butterfly valve with reduced nominal diameter (reduced by one or two nominal sizes) and can be used to achieve higher control accuracy. This will mean that complex reducing fittings will no longer be required.
