V241
The V241 is a high quality general purpose valve. Polished stainless
seats provide high differential pressure capability and low leakage.
Suitable for a wide range of applications such as heating, cooling, air
handling and domestic hot water systems. The valve can handle hot
and cold water with phosphate, hydrazine and antifreeze additives.
If the valve is used for media at temperatures below 0 °C (32 °F),
it should be equipped with a heater in order to prevent ice formation
on the valve stem.
