V321
The V321 is a large flanged valve with a stainless steel seat for high pressure
drops
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 heater in order to prevent ice formation on the valve stem.
Design 3-way plug mixing valve
stem up closed (A port/B-AB open)
Pressure class PN 16
Connection Flange according ISO 7005-2
