Note: 1. The ball seat is designed for F22 type internal thread. 2. The above-mentioned valve ball and valve seat assembly includes a valve ball and a valve seat. The double-sealed valve ball and valve seat assembly also contains only a standard ball or a replaceable ball. 3. Using a replaceable (small size) valve ball in a standard valve cover will damage the valve cover due to the increased clearance between the valve ball and the valve cover guide. To use replaceable (small size) valve balls, a valve seat with replaceable seat sealing tape is required. To use standard valve balls, a valve seat with standard seat sealing tape is required.
a. As shown above, valve balls V12-175 and V12-200 are used for standard ball and seat assemblies as well as replaceable ball and seat assemblies. b. See Table V12 Valve Ball and Table V13 Valve Seat Dimensions. c. There are two sealing belts on the sealing surface of each end of the double sealing belt valve seat, which are respectively adapted to the standard ball and the replaceable ball.
