Heavy brass bodied check valves with two tapping holes. A 1/4" female pipe thread tapping on the outlet side of the check valve poppet, and a 1/8" female pipe thread tapping on the inlet side of the check valve poppet. These check valves are female iron pipe thread on each end. These check valves are normally used with drain back well systems where the line must drain back into the well to prevent freezing.

  Brass swing check valves are normally installed in a horizontal position and are not spring loaded. Brass body valves with female pipe thread connection are rated at 125 psi. The brass swing disc seats directly against a ground seat in the brass valve body.
