V231
The V231 is a flanged PN25 valve with a very high rangeability
The valve is suitable for primary district heating circuits as well as hot
and chilled water applications where high pressure or where a very fine
resolution of flow control is required.
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.
