Store the actuator carefully before installation, preferably indoors in a dry place. Do not take the actuator to the intended location and do not remove protection plugs from the pipe connections until the actuator is installed.
3.3 6 BC 71 en Demounting the actuator from the valve CAUTION: Take the weight of the actuator or valve combination into account when handling it! CAUTION: Beware of the cutting movement of the valve! for example an anti-corrosive like Cortec VCI 369. The housing can also be filled with semi-fluid water-repellant grease (for example Mobilux EP2) approximately halfway when the piston rod is in the lower position. If you remove the stop screw, adjust the limits after lubrication or grease filling! 4.

Mounting the cover on the housing CAUTION: Keep your fingers, tools or other items out of the housing while operating the actuator with the cover open! 18 24 BC9...16 BC17...40 Fig. 10 18 18 24 24 *) BC50...
4.4 6 BC 71 en Replacement of linkage bearings and O-rings CAUTION: Don’t dismantle a pressurized actuator! Remove the actuator from the valve Guide the actuator so that the piston is at the outermost end of the cylinder. Release the pressure from the cylinder. Remove the housing cover (2). Loosen the fastening screw (29) of the bearing unit (5), see Figure 8. Turn the lever (3) so that the bearing unit is detached from the piston rod (10).
6 BC 71 en 5 9 MALFUNCTIONS Table 2 lists malfunctions that might occur after prolonged use. 6 TOOLS For maintenance of the actuator, you will need a few special tools in addition to the usual ones. The following can be ordered from the manufacturer: Table 2 For actuator removal: - Extractor For piston seal installation: - Tie ring For cylinder base removal: - Lock nut key 7 ORDERING SPARE PARTS NOTE: Use only original spare parts. This ensures proper functioning of the actuator.
