No. 6 Gorton (G6S8) and other STRAIGHT valves
I was thinking of adding a No. 6 Gorton (G6S8) to increase the venting capability of one of my second floor radiators (it is the the last one on it's branch of pipe) and was wondering - all the Gorton values seem to be straight. Does that mean I need a 90 degree elbow to be able to use them on my radiators or can they be screwed it directly as they are?
