1. For conventional disc valve bodies, use either valve shaft keyway.
2. When viewed from actuator side of valve body.
3. For 60‐degree rotation with PDTC action, the coupling and actuator output shaft assembly will offset 30 degrees clockwise (for actuator housing construction style B), or counterclock
wise (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 mm (3/4 inch) valve shafts.

WARNING
To avoid personal injury and equipment damage from moving parts, keep fingers and tools clear while stroking the
actuator with the cover removed.
9. Stroke the actuator and adjust the down travel stop so that the valve ball or disc is in the desired position.
10. Make sure that the travel indicator pointer matches the ball or disc position. Remove and install in the proper
position if necessary.
