Butterfly Valve for Hot Air and Flue Gas BVH

Butterfly Valve BVHThe butterfly valves BVG, BVH, BVHM and BVHS 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.

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.

Using a spiral spring, which compensates for the play in combination with the actuator IC 40, it is possible to move the valve disc to the required angle with almost zero hysteresis.

Features

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