Same construction and contents as the No. 300, however a drilled and tapped side outlet, on either inlet or outlet side, has been added. Heavy bosses have been added to provide proper thread length for leak-proof side connection. The connection can be furnished for either 1/8" or 1/4" taper pipe thread. When ordering, specify whether tapping is to be on the inlet or outlet end of the valve and what size connection is required. Generally used when attaching a pressure switch, pressure gauge, snifter valve, drain or blow lines, or adding chemicals. |
