VG311F 65-150C (VG321)
The VG311F...C is a large flanged general purpose valve
The valve is suitable for a wide range of mixing applications with hot or chilled
water in heating cooling and air handling systems.
If the valve is used for media at temperatures below 0 °C, it should be equipped
with a stem heater in order to prevent ice formation on the valve stem.
