The Vent-Rite #11 is for free-standing radiators with a 1/16" vent port and 1/8" connection. It operates at 6 PSI.

The Vent-Rite #11 air valve has been designed to eliminate air in any one pipe stream radiator system as quickly as possible to insure rapid and efficient heating. It will open and close at pressure up to 6 PSI. Do not use at system pressures above 10 PSI.

This air valve is easily installed. Its standard 1/8" male connection makes it interchangeable with almost any other valve.

Notes: Operating pressure (drop away) is the maximum pressure at which the vent will continue to open and close due to the change of temperature. The vent may be used with slightly higher pressure providing it drops below the operating pressure between each ring cycle.

Features:

• Every Vent-Rite vent is factory assembled, tested & inspected in the USA!
• Each valve is individually packaged with external labeling for convenience & maintenance
• All brass internals with nickel plated & hand polished exterior
• Adjustable vents have wide adjustment conveniently located below the steam path
