V311
The V311 is a flanged valve with a soft seat for tight shut off
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.
