Description
The VF208W is a new generation butterfly valve for the isolation and control of water for HVAC systems. The valve can be operated either by an electric actuator or hand using a handlever. Nodular iron construction provides a long life and high corrosion resistance. The EPDM soft seats provide tight shut off and zero leakge, for a better energy saving, maintenance free, double sealing of stem, centrical disc bearing. Valve size: DN80, Flange, uncharacterized flow, kvs: 375 m³/h. Constructed and flanged to a PN16 pressure class. ΔPm of maximum 600 Kpa. EPDM seals provide a working temperature range of -10 °C to + 100 °C, the soft seat seal ensures a tight close off with no leakage. Uncharacterized flow characteristics provide a good flow control, integrated dew point barrier. No linkage kits required.
