Butterfly Valves

Butterfly Valve BVG

Butterfly Valve BVG

The butterfly valve BVG is designed to adjust volumes of gas, cold and hot air, and flue gas on various appliances and flue gas lines. 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.

Butterfly Valve BVH

Butterfly Valve BVH

The butterfly valve BVH is designed to adjust volumes of gas, cold and hot air, and flue gas on various appliances and flue gas lines. The butterfly valve BVH is used for processes that require very precise adjustment of the flow rate or low leakage. In conjunction with the stop bar, the valve disc ensures very low leakage rates.

Butterfly Valve BVHM
