TEMPERATURE CONTROL VALVE A691A
This listing is for a thermistatic radiator valve which is new old stock out of box and in good condition. Built in the USA for years of dependability, and when properly installed and adjusted will remain room temperature within 1.5 degrees F of the desired setting. It's divided into three main settings: COLD, NORMAL, and HOT. Side opening is about 15/16" threaded inside diameter and bottom opening is 1" threaded outer diameter. This allows you to zone a radiator to a different setting than other rooms or to adjust the temperture more or less than other room tempertures. Great for saving money on heating costs. See pictures for more details and please make sure that this is the part you need, as it is a non-returnable item. Thank you.
