For more details about valves,positioners and accessories, refer to the separate installa-tion, Operating and Maintenance Instructions of the par-ticular and operationThe B1J series actuators are pneumatic cylinder actuatorsdesigned for control and shut-off service.

3 The linkage bear-ings have material options. The robust cast-iron housingefficiently protects the mechanism from ambient dust spring provides the required safety function; the valveeither opens or closes if the air supply is mounting face dimensions of the B1J actuator complywith the ISO 5211 the B1J type, the spring is located on the piston rod secondary shaft of the actuator, operated by the spring,rotates clockwise as seen from the pointer cover side. Thepiston then moves towards the end of the cylinder. The B1 Jtype is normally applied for the spring-to-close operation,as it normally closes in the clockwise direction. The two key-ways in the secondary shaft are positioned at an angle of90 to each other, making it possible to change the positionof the actuator in relation to the valve, see Fig.

4 1. In the B1JA type, the spring is located in the cylinder endside. The secondary shaft, operated by the spring, rotatescounter-clockwise as seen from the pointer cover side. Thepiston moves away from the cylinder end. The B1JA type isused for the spring-to open function, see Fig. size of the spring actuator is selected according to thetorque given by the spring. It is, however, important tocheck that there is sufficient supply pressure to give therequired torque in the opposite are located in the upper end of the cylinder and inthe lower end of the housing to regulate the length of thepiston stroke and also the rotation angle of the actuatorshaft. markingsThe actuator is provided with an identification plate, seeFig.

An actuator can also be returned to the manufacturerfor recycling and disposal against a precautions 2 TRANSPORTATION, RECEPTION AND STORAGEMake sure that the actuator and associated equipmenthave not been damaged during transportation. Store theactuator carefully before installation , preferably indoors in adry place.

7 Do not take it to the installation site or removethe protective caps of ports for piping until just the actuator as shown in Fig. 4: in a horizontal positionfrom the stop screws, in a vertical position from an eye boltscrewed in the place of a stop screw. Do not use the lug forlifting dual-cylinder actuators. Refer to Section 9 forweights. Fig. 3 Output torque as a function of turning angleCAUTION:Don t exceed the permitted values!Exceeding the permitted pressure value marked on theactuator may cause damage and lead to uncontrolledpressure release in the worst case. Damage to the equip-ment and personal injury may :Don t dismantle a pressurized actuator!Dismantling a pressurized actuator leads to uncontrolledpressure release.

8 Shut off the supply pressure and releasepressure from the cylinder before dismantling the , personal injury and damage to equipmentmay :Follow the Instructions given on the actuator warningplates!CAUTION:Before opening the cylinder fastening screws, releasespring tension directed on actuator warning plate andin these Instructions ! / / / M / :Don t operate the actuator manually by turning fromthe lever arm!CAUTION:Don t dismantle the spring package!The spring package within the cylinder is preloaded. Thelock-welded fastening screw of the piston must never beopened or the spring package dismantled. The piston, pis-ton rod, spring and spring plate of the B1J actuator arealways delivered as a pre-assembled :Don t use the lever in the torsion arm for manual oper-ation when the actuator is pressurized!

9 Shut off the supply pressure and release pressure from thecylinder before using the hand lever. Note also thedynamic torque caused by the pipe , personal injury and damage to equipmentmay :Take the weight of the actuator or valve combination into account when handling it!Do not lift the valve combination from the actuator, posi-tioner, limit switch or their piping. Lift the actuator asdirected in Section 2, lifting ropes for a valve combinationshould be fastened around it. The weights are shown inSection 9. Dropping may result in personal injury or dam-age to the :Potential electrostatic charging hazard, do not rub surfacewith dry 4 Lifting the actuator6 BJ 71 en5Ta b l e 13 MOUNTING AND gas supplyDry compressed air or natural gas can be used in actuatorsin open-close operation, no oil spraying is needed.

10 Clean,dry and oil-free instrument air must be used for cylinderactuators with a positioner. The air supply connections arepresented in the dimensional drawings in Section 9. Themaximum supply pressure is the actuator on the valve Install the actuator so that the shaft of the valve or anyother device to be actuated goes into the shaft bore of theactuator. If the bore is larger than the shaft diameter, use akeyed shaft adapter sleeve or bushing. There are two key-way slots in the shaft bore of the actuator at an angle of 90 .These allow the installation position of the actuator to bechanged in relation to the valve. Metso valves have a bevelat the end of their shafts to facilitate installation . The installation position can be selected freely, but Metsorecommends installation with the cylinder upright.
