Frequently Asked Questions

What are Elektrogas VF, VFT, and VFH butterfly valves used for?

Elektrogas VF, VFT, and VFH butterfly valves regulate and control air and gas flow in combustion processes. They are suitable for industrial kilns, drying stoves, smelting, and annealing furnaces. The VF and VFT handle air and non-aggressive gases, while the VFH handles heated air and flue gas.

What are the specifications of Elektrogas VF, VFT, and VFH butterfly valves?

VF and VFT valves handle air and non-aggressive gases (EN 437) at media temperatures up to 60 °C (200 °C optional) and operating pressure 0 to 500 mbar. VFH handles heated air and flue gas up to 450 °C and 0 to 150 mbar. VF is aluminum (DN40 to DN150), VFT is aluminum (Rp 3/4 to Rp 2), and VFH is cast iron (DN40 to DN200).

Where to buy Elektrogas butterfly valves in Singapore?
