Butterfly Valve BVGButterfly Valve for Gas and Air BVG

  • For gas, air, hot air and flue gas
  • Low leakage rate and pressure loss
  • High control accuracy
  • Reduced nominal diameters
  • Can be mounted directly onto the actuators IC 20 or IC 40
  • Suitable for intermittent operation
  • Low-maintenance operation

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.
