Elektrogas Control Valves VF VFH

VF VFH
Butterfly valves for air and gas 
VF and VFH butterfly valves are designed for regulation and control of air and gas flow.
Valves can be operated manually using a lever (to setup the high-fire rate of the burner) or automatically using a servomotor (modulating or staged control) or a solenoid actuator (two-stage control).
The setting can be monitored on a graduated scale, this allows  precise regulation ratios.
This type of device is suitable for air and gas adjustment in combustion processes, like industrial kilns, drying stoves, smelting and annealing furnaces.
