Description

Elektrogas VF butterfly valves are designed for regulation and control of gas and air flow in combustion processes. Valves can be operated manually using a lever (to set up the high-fire rate of the burner), or automatically using a servomotor (modulating or staged control) or a solenoid actuator (two-stage control).

Please note: These butterfly valves were designed with the ISO bolt circle in mind, which means they have an OD which is larger than the ANSI bolt circle at the 1-1/2” (DN40) size. That difference decreases as they approach the 4” (DN100) size. In sizes above 4” (DN100), these valves have an OD which is smaller than the ANSI bolt circle. Therefore, valve sizes which are larger than the ANSI bolt circle are modified to create grooves for the bolts. Valve sizes which are smaller than the ANSI bolt circle should be used with spacers or with ISO flanges.
