Two-way Pressure Balanced Globe Valve, Flanged, PN 16
The 221F 65-150C valve is primarily intended to be used in heating, cooling and air conditioning application.
The 221F 65-150C valve can be used with the following types of fluids:
• hot water, or deaerated cooling water.
• deaerated water with glycol-type antifreeze agent (max.50%)
With cooling medias at temperatures below 0°C a stem heater must be fitted, to protect from stem seizure due to freezing.
