STORAGE the pipes. Pipes must be flushed with air to clean the passages. Where sealants are been used for threaded connections, care must be taken to avoid excess material been forced into the actuator ports. The Compact actuator has been packaged to provide protection during shipment, however, it can be damaged in transport. Prior to storage, inspect the actuator for shipping damage. Keep the actuators in their original packing box during storage. It is recommended to keep the actuators in a clean and dry environment until ready for use. The actuator has two air ports, which should be...

AIR CONNECTIONS Double Acting (DA) The actuator air connections are marked A and B . Port B connects to a chain of holes to all the four pistons. The air passes into the Namur cover (or insert) and through holes which are connented to the two neibouring pistons. Each piston recieves the air flow from two directions which ensures a quick response. Pressure entering Port A to open: Center chamber pressurized. Pistons move outward and the pinion rotates counter clockwise (CCW). In sizes C15 to C45 port A is to the right and port B to the left. > Pressure entering Port B to close: Outside...

NAMUR Solenoid Mounting Air supply connection is done by mounting a solenoid directly onto the Namur cover which has a mounting pad conforming to the Namur standards. (Only Solenoids made to the NAMUR standard can be mounted in this way.) The Compact II actuator can also be piped with solid or flexible tubing from remote solenoid valves. > All actuators are assembled with a highly visible indicator or puck. The indicator and puck have interchangeable snap-onԔ flow direction arrows for identification of valve position. > The arrows provide any type of pattern according to the valve ports....

General Before performing any disassembly operations make sure you read all the warnings and safety instructions in this leaflet. Do not attempt to disassemble the actuator while it is still connected to the valve or to any ancillary. Verify that the actuator is not pressurized. Check that the air ports are vented and spring return actuators are in the fail close position. Work in a clean area, free of dust, debris, grease, corrosives and moisture. For security and comfort do the repairs on a table with a vice and available air supply. Clamp an adaptor to the vice and place the actuator...

Top View Side View Leftscrew 4.1 Looking at the actuator as shown to the left, withdraw the left of each pair of stroke adjustment screws (19) approximately 6-10 mm outward. This will enable the stop to rotate beyond its 90 limit so the pistons can come out. It may require a little force to release the adjustment screws as they are assembled with a thin layer of LoctiteЮ 221. > Namur CoverSide Leftscrew Leftscrew 4.2 Grip the actuator body with both hands and rotate it in the CW direction to eject the 4 pistons out of their cylinders. The 4 pistons will eject out of the actuator body as...

Top View Top View Bottom View General Before performing assembly, clean the grease in the cylinders and all the actuator parts. Check the cylinder for any scratches. The surface should be smooth and without any damage, debris, rust or other contaminants. Apply grease to all the parts prior to assembly. > StopProtrusions 45 45а 6.1 If you have removed the pads, push them back into their holes as shown in section 4.4. 6.2 If the stop (13) has been removed from the pinion (12), insert it back making sure the orientation of the two stop protrusions are at 45 to the Namur slot as shown in the...
