Description
Honeywell Kromschroder BVG Butterfly Valve for Gas Flow Rate Control
The butterfly valves are designed for control ratios up to 1:10, and with the mounted actuator they are suitable for regulating flow rates for modulating-controlled or stage-controlled combustion processes.
BVG for gas, BVA for air. These butterfly valves BVG..H, BVA..H can also be supplied with manual adjustment.
Flow rates can be set and fixed using a butterfly valve with manual adjustment, for example to limit the high-fire rate on the burner. A scale indicates the set angle of opening. Butterfly valves BVG, BVGF, BVA and BVAF with reduced nominal diameter (reduced by one or two nominal sizes) can be used to achieve higher control accuracy. This will mean that complex reducing fittings will no longer be required.
Various adapter sets with square shaft, free shaft end or lever are available as accessories. 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.
Butterfly valves BVGF and BVAF work clearance-free. In case of change of direction, the butterfly valve adjusts to the setpoint without delay. The butterfly valve thus reaches the required position more quickly.
In summary:
BVG = Butterfly valve for gas
BVGF = Clearance-free butterfly valve for gas
BVA = Butterfly valve for air
BVAF = Clearance-free butterfly valve for air
IBG = Butterfly valve for gas with actuator
IBGF = Clearance-free butterfly valve for gas with actuator
IBA = Butterfly valve for air with actuator
IBAF = Clearance-free butterfly valve for air with actuator
