Globe Valves
V341
The V341 is a high quality general purpose valve. Polished stainless seats
provide high differential pressure capability and low leakage.
The valve is suitable for a wide range of applications such as heating,
cooling, air handling and domestic hot water systems. The valve can han-
dle hot and cold water with phosphate, hydrazine and antifreeze additives.
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.
