Quick, uniform distribution of heat to all radiation is the first essential to perfect performance. This requires balancing the radiation by controlled venting. Vent-Rite’s #1 non-vacuum vents are adjustable and all vents are designed for positive action and straight line venting. They function automatically to vent the air. If, through an unusual condition, the vent is filled with water, the vent port automatically closes.
The Vent-Rite #35 is a main vent with a 3/32" vent port and a 3/4" male x 1/2" female connection and operates at 3 PSI
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.
Replaces the Dole #4 and Hoffman #45 vents.

Yes, I would recommend this to a friend
I live in a basement apt. and I had to replace this valve because the old one was spitting and hissing almost constantly. It was very old and needed to be replaced . The new one is very quiet and was very easy to replace
