1. For actuators with J mounting.
2. For conventional disc valve bodies, use either valve shaft keyway.
3. See figure 10 for reference coupling orientation to use with this table.
4. When viewed from actuator side of valve body.
5. For 60-degree rotation with PDTC action, the coupling and actuator output shaft assembly will be offset 30 degrees clockwise (for actuator housing construction style B) or
counterclockwise (for actuator housing construction Style A) in the lever when viewed from the splined end of the actuator shaft. 30 degrees is one spline tooth for 9.5, 12.7, and 15.9
mm (3/8, 1/2, and 5/8-inch) valve shafts and two spline teeth for 19.1 through 38.1 mm (3/4 through 1-1/2 inch) valve shafts.
