GENERALThis instruction manual contains important information regarding the installation , operation, and troubleshooting of the Jamesbury Valv-Powr VPVL Mod D Value-Line Double-Opposed Piston Actuators. Please read these Instructions carefully and save them for further the use of the VPVL X is application specific, many factors should be considered when selecting an actuator for a given application. Therefore, some of the situations in which the actuators are used are outside the scope of this manual. If you have any questions concerning the use, application or compatibility of the actuator with the intended service, contact Neles for more read these Instructions carefully and save them for further WARNING:LOSS OF AIR PRESSURE MAY CAUSE SPRING-RETURN ACTUATORS TO MOVE TO THEIR FAILURE POSITION.

3 APPLYING AIR PRESSURE OR CONTROL SIGNAL TO VALVE/ACTUATOR ASSEMBLY MAY CAUSE THE ASSEMBLY TO OF MOVEMENT OF THE VALVE AND ANY LINKAGE BETWEEN IT AND THE ACTUATOR. KEEP HAND, BODY PARTS, TOOLS AND OTHER OBJECTS OUT OF THE WAY OF MOVING PARTS. FAILURE TO DO THIS MAY RESULT IN DAMAGE OR PERSONAL INJURY!ALWAYS KEEP HANDS AND CLOTHING AWAY FROM THE VALVE PORTS. A CLOSING VALVE ACTS AS A CUTTING NOT TRY TO MANUALLY OPERATE A PRESSURIZED A PRESSURIZED ACTUATOR WILL LEAD TO UNCONTROLLED RELEASE OF PRESSURE. SHUT OFF SUPPLY PRESSURE AND RELEASE THE PRESSURE FROM THE ACTUATOR BEFORE DISASSEMBLY. FAILURE TO FOLLOW THESE Instructions MAY RESULT IN DAMAGE OR PERSONAL INJURY!DISASSEMBLY OF A SPRING-RETURN ACTUATOR MAY BE ATTEMPT TO DISASSEMBLE THE SPRING CARTRIDGE ASSEMBLY OF A SPRING-RETURN ACTUATOR.

4 DISASSEMBLY OF THE SPRING CARTRIDGE ASSEMBLY MAY RESULT IN SERIOUS PERSONAL INJURY! IF Maintenance IS REQUIRED THE ENTIRE SPRING-RETURN ACTUATOR SHOULD BE DIRECTED TO A NELES SERVICE OFF AND BLEED ALL SUPPLY LINES BEFORE installation OR SERVICING THE ACTUATOR. BEFORE INSTALLING THE VALVE AND ACTUATOR, BE SURE THAT THE INDICATOR POINTER ON TOP OF THE ACTUATOR (AND THE IDENTIFICATION PLATE IN FEMALE ACTUATORS) ARE CORRECTLY INDICATING THE VALVE POSITION. FAILURE TO ASSEMBLE THESE PRODUCTS TO INDICATE CORRECT VALVE POSITION COULD RESULT IN DAMAGE OR PERSONAL INJURY!THE ACTUATOR MUST BE SIZED ACCURATELY FOR PROPER OPERATION. REFER TO INFORMATION ON THE ACTUATOR END OF STROKE TORQUES AND THE APPROPRIATE VALVE BULLETIN FOR Operating SERVICING A VALVE ACTUATOR ASSEMBLY, THE BEST PRACTICE IS TO REMOVE THE ENTIRE ASSEMBLY FROM SERVICE.

5 IF THE ACTUATOR IS REMOVED FROM THE VALVE, IT SHOULD BE REMOUNTED ON THAT SAME VALVE AFTER SERVICING IS COMPLETED. THE ACTUATOR MUST BE READJUSTED FOR PROPER OPEN AND CLOSE POSITION EACH TIME IT IS NOT USE VDI/VDE MOUNTING HOLES TO LIFT AN AN ACTUATOR ABOVE ITS TEMPERATURE LIMITS MAY DAMAGE INTERNAL AND EXTERNAL COMPONENTS AND MAY RESULT IN PERSONAL INJURY! Operating OVER THE PUBLISHED PRESSURE LIMITS OF THE ACTUATOR MAY RESULT IN DAMAGE OR FAILURE OF THE ACTUATOR HOUSING, AND MAY RESULT IN PERSONAL INJURY! Handling VPVL Actuators When handling the actuator or valve/actuator assembly, take its weight into account! Approximate actuator weights are shown in the technical bulletin. Never lift the actuator or valve/actuator assembly by the actuator positioner, limit switch, their piping, or an NPT air connection.

6 Handling of the actuator should be accomplished using lifting straps. Failure to follow these Instructions may result in damage or personal injury from falling parts.

Operating Media: Air, Nitrogen Air Quality: Acc. to ISO 8573-1 Solid particles: Maximum particle size 30 m Humidity: Dew point equal to -20 C or 10 C / 18 F below ambient temperature2. Air Supply: 116 psi (8 bar) Temperature Range: Standard -40 F to +176 F (-40 C to +80 C) High Temp 5 F to +302 F (-15 C to +150 C) Low Temp -60 F to +176 F (-51 C to +80 C)4.

Exhaust air exits at Port 4 (acounterclockwise rotation is obtained).Loss of air pressure allows springs to force pistons toward centerposition with exhaust air exiting at Port 2 (a clockwise rotation isobtained).Figure 23. General1. Check to see that the desired failure mode is correct (Figures 1 & 2). In the spring-to-close mode, the actuator will cycle clockwise to close upon loss of pressure. If the spring-return actuator is not set up in the configuration desired, follow the disassembly procedure section Reverse the orientation of the pistons, then reassemble following the assembly procedure, section Mount the actuator to the valve, following the direction in the linkage AMI or valve Connect a regulated air supply to the NPT fitting in the actuator housing.

8 CAUTION: The maximum Operating pressure is 116 psi (8 bar).4. Adjust the stop screws following ASSEMBLY Section Operation1. The actuator series, size, Operating pressure, Operating temperature, output torque, spring directions, and drive type is determined by the actuator The label lists the actuator series, size, Operating pressure, maximum pressure, and serial Actuator designation example, VPVL300SR6BD is a spring-return series, VPVL300 double-opposed piston actuator that has 80-psi ( ) springs, a Teflon - coated anodized housing (protection B), an end-of-spring-stroke output torque of FT LBS ( N m).4. GeneralAlthough Neles Jamesbury actuators are designed to work under severe conditions, proper preventative Maintenance can significantly help to prevent unplanned downtime and in real terms reduce the total cost of ownership.

9 Neles recommends inspecting actuators at least every five (5) years. The inspection and Maintenance frequency depends on the actual application and process condition. NOTE: All VPVL actuator fasteners are metric. Under normal Operating conditions the actuator requires only periodic observation to ensure proper adjustment. Repair kits are available to replace seals and bearings (soft parts). These parts are identified in (Figure 23) and listed in (Table 3). (Table 1) below lists kit part DisassemblyWhen disassembly of the actuator is required for Maintenance , remove the actuator from the valve. Ensure proper lifting procedures are followed when moving or carrying actuators. CAUTION: Do not use the M5 VDI / VDE mounting holes or the M6 hole in the pinion for lifting the actuator.
