22 and the closure plug I8 are formed with aligned
bores 25 and 21 of the same diameter and in
which there is journalled a stub shaft 28.
A radial valve mounting arm 29 of sheet metal
is attached to the inner end of the stub shaft 28
in any suitable manner, such as by forming a
shoulder on the stub shaft, a hole in the arm,
placing the shaft through the hole and peening
over the protruding end of the shaft. An arcu

may be formed integrally with, the radial arm
29. This arcuate deflector valve 30 extends

latter is to be connected in the supply main with
respect to the direction of flow of the heating

It should be noted that, While the primary
function of the arcuate valve member 30 is to in
terrupt the iiow through the branch connection
i3 when desired, it can also be set by suitable ad
justment of the operating arm 3| to some position
