Here is a picture of the No. 3C A:~ ,7*'-- These Dole Nos. 3A, 3B and 3C Air Valves are designed to meet the in creasing demand for popu larly priced straight shank valves that give satis factory venting perform ance on systems where ex treme water conditions are encountered. They posi tively do not "stick" or spit water and they insure free venting at any pres sure up to 15 lb. Look at the illustrated installation suggestions. Notice that a nipple con nection is not required when Dole No. 3 Air Valves are installed on either cast iron or copper convectors, provided the heater has sufficient space to accommodate the siphon tube. Do not cut or bend this tube. Another important ad dition which rounds out the Dole line is the DOLENO. 7 SIGNAL AIR VALVE for venting con cealed hot water convec tors or radiators.
