The shaft is 12/32 in diameter the outside diameter of the valve is 13/32 the inside diameter of the valve seat is 8/32 The length of the valve is @ 5.75 in The valve clip holder at top of valve is 7/32 deep. Then this has a .25 in hold space/ then has a .5 inch taper to the shaft width do you have a replacement valve like this? It is stamped Eaton 28EX
