Yes it is simple ball check valve made from 9/16" brass hex stock.
The OAL length is 1 9/16" long.
The through hole I.D. above the ball is .35" This does not go all the way to the bottom, but provides the taper for the ball to rest on (shut off)
The hole size under the ball is not kown? but should be smaller than the ball O.D. maybe 3/4 size of ball O.D. This hole connects to the six inlet holes.
The Ball Diameter is 3/16 – 1/4 " aprox?
The cross pin is close to a #35 drill size made from brasss rod pinned or staked to prevent movement. (You could also solder or braze)
Location is .620" down from the top (thread side)
The water inlet are six holes drilled on each side of hex a # 39 drill is a good fit, hole location 1.35" from top (thread side)
Thread size is 1/2 X 18" check your motor to be sure .50" length.
