4. WARNING Refer to the WARNING at the beginning of the Maintenance section in this instruction manual CV500 Valve Instruction Manual November 2011 D101640X012 Isolate the control valve from the line pressure release pressure from both sides of the valve body and drain the process media from both sides of the valve If using a power actuator also shut off all pressure lines to the power actuator release all pressure from the actuator Use lock out procedures to be sure that the above measures stay in effect while you work on the equipment CAUTION To avoid increased leakage increased valve component wear or possible damage to the valve body ball shaft and bearings resulting from a sharp blow to the shaft use a wheel puller to separate the actuator parts from the drive shaft Do not drive the actuator parts off the drive shaft since this could move the valve bearings shaft and ball away from proper alignment causing improper seating of the ball Such misalignment may result in damage to valve components if the valve is returned to service without disassembly and inspection of the valve ball alignment 2 If necessary remove the screws key 25 and hex nuts key 26 Then remove the actuator while referring to the actuator instruction manual for assistance 3 Remove the packing nuts key 16 For NPS 3 through 8 remove the packing follower key 14 For NPS 10 and 12 remove the packing flange key 45 and th
