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 in the 1½" to 4" sizes, and an OD which is smaller than the ANSI bolt circle in the 5" to 6" sizes. Therefore, valves in the 1½" to 4" range are modified to create grooves for the bolts in the ANSI circle. Larger valves should be used with spacers or ISO flanges.
