V231/40/25 Control Valve

The V231 valve is widely used in central heating&cooling, and hot water control systems. The valve works with the following media:

• hot and cold water,

• phosphate-containing water or with the addition of hydrazine,

• water with anti-freezing agents, e.g. glycol

For a medium cooled below 0°C, the valve should be equipped with a stuffing box heater to protect against freezing.
