V232
The V232 is a pressure balanced flanged PN25 valve with high rangeabil-
ity and a high differential pressure capability. The balanced plug enables a
low actuating force to control the valve.
The valve is suitable for primary district heating circuits as well as hot and
chilled water applications where high pressure or a very fine resolution of
controllable flow 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.
