BVH, BVHR, BVHS, BVHM The butterfly valves 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 they are suitable for regulating flow rates for modulating-controlled or stage-controlled combustion processes. The butterfly valve BVH, BVHR, BVHS is used for processes that require the very precise adjustment of the flow rate or low leakage. In conjunction with the stop bar, the valve disc ensures very low leakage rates. BVG, BVA BVG for gas, BVA for air....

Butterfly valve BVH is suitable for applications up to 450°C. The BVHR can be used at a medium temperature of up to 550°C. BVHM Butterfly valve BVHM is used in intermittent mode. Solenoid actuator MB 7 is available as an actuator for the BVHM. IBG, IBGF, IBA, IBAF, IBH, IBHR, IBHS Solenoid actuator MB 7 and butterfly valve BVHM are used in intermittent mode. The low- and high-fire rates can be adjusted independently of each other. For detailed information on solenoid actuator MB 7, see www.docuthek.com, Technical Information bulletin MB 7. Butterfly valves BVG, BVGF, BVA, BVAF, BVH, BVHR or...

Examples of application IBG, IBGF, lambda correction VAS If the burner is to be operated with excess gas or air for reasons of process operation, the butterfly valve with actuator IBG can be used to correct the lambda value. The butterfly valve BVA with manual adjustment is used to adjust the highfire rate. IBA, IBAF, adjusting the burner capacity VAS In pneumatic ratio control systems, the butterfly valve with mounted actuator IBA determines the air volume for the required burner capacity. The butterfly valve BVA with manual adjustment is used to adjust the highfire rate. IBH, IBHR, hot...

IBHS, safety closing function in the event of a mains voltage failure VAS The safety closing function ensures that in the event of a mains voltage failure air cannot stream into the furnace without being under control. The butterfly valve with actuator IBHS is used in the air circuit. The butterfly valve BVA with manual adjustment is used to adjust the highfire rate. BVHM in intermittent mode VAS Solenoid actuator MB 7 and butterfly valve BVHM are used for intermittent switching of the burner. The MB 7 is equipped with a flow rate adjustment device. The low- and high-fire rates are thus...
