Be sure rotary stops on valve are removed or adjusted to allow actuator stops to do the install actuator and bracket to valve being sure to leave all fastener connections hand tight.

2 If possible, stroke valve and actuator to a half open position 45 and physically shift actuator back and forth until coupling and all fasteners are relaxed then tighten all bolts and nuts. this procedure will accurately align valve stem to actuator output shaft and prolong valve stem seal 1 - Models A, B, C And ssingle acting actuatortwo cylinders with jumperdouble acting actuatortwo cylinders with jumpersupplyexhaustexhaustsupplysolenoid or positionersolenoid or 18/032. MaintEnancE Morin ACtuAtors are factory lubricated and in general do not require periodic lubrication or maintenance while in service. ACtuAtors should be visually inspected periodically for corrosion damage and promptly repaired. ACtuAtors should be operated at least annually to assure proper correct length mounting bolts! Mounting bolts used in actuator mounting pad may interfere with the actuator rotary mechanism. Select bolts that will not extend more than two threads above the back of the mounting Cycle valve / actuator assembly and observe for smooth Adjust travel stops for perfect alignment in both open and closed positions.

3 Note: if jackscrew override is installed, please refer to section 2B for stroke tubing connections - some Models utilize two pistons for added power. spring return (single acting) dual cylinders designs require one jumper to make the supply port common on both pistons. double acting (air to air) dual cylinder designs require two jumpers. see Figure 1 for typical Models A, B, C And s PneuMAtiC ACtuAtorsOperatiOn and Maintenance instructiOns3. JackscrEw oVErridEthe jackscrew option is intended for infrequent or emergency on-site operation of the automated operating instructions1. disengage power supply and vent air from operate the handwheel to drive the actuator into the desired position. Valve position can be verified by checking the actuator position indicator. For Models 006 through 270, the jackscrew must be returned to the fully retracted position before actuator can resume normal operation. Back the jackscrew out until it stops.
