IntroductionScopeThe following instructions are designed to guide the userthrough the installation and maintenance of the V-LOG trim,installed in globe and angle style reciprocating valves.The V-LOG product is part of Masoneilan’s EngineeredProduct portfolio, and is custom designed to fit ourcustomer’s most difficult applications. For this reason, thisinstruction manual will refer to specific drawings that applyonly to the valves that are specified for use on this project.For further detailed information on your specific V-LOG valvedesign, please contact the Masoneilan factory.If major system or piping modifications (or repairs) areperformed, thorough flushing and blowdown of the systemwill be required prior to reinstalling the V-LOG trim. Sacrificialflushing trim should be installed in this valve to protect theintegrity of the V-LOG flow passages. Failure to follow thiswarning will violate the valve warranty agreement and couldresult in control instability, excessive noise levels, and valveleakage.Serial PlateThe serial plate is usually fixed to the side of the actuatoryoke. It indicates several things including, the size and typeof valve, the pressure class, the body and bonnet material.After Sales ServiceMasoneilan offers After Sales Service comprised of highlyqualified technicians to support the installation operation,maintenance and repair of its equipment. Contact the localMasoneilan representative or Masoneilan factory locatedclosest to you.Spare PartsOnly Masoneilan replacement parts should be usedwhen carrying out maintenance operations. Obtain replacementparts through our local representatives or MasoneilanParts Department.When ordering spare parts, the MODEL AND SERIALNUMBERS indicated on the manufacturer’s serial plate MUSTBE GIVEN. The serial plate is on the side of the actuator yoke.Actuator and AccessoriesActuators and other valve accessories have their own instructionmanuals, that provide information on the pneumatic,electric, and hydraulic connections.InstallationPiping CleanlinessBefore installing the valve in the line, clean piping and valveof all foreign material such as welding chips, scale, oil,grease or dirt. Gasket mating surfaces must be thoroughlycleaned to ensure leak-free joints. Sacrificial start-up fixturescan be purchased from Masoneilan to protect the operationaltrim during the installation and line flushing phases.Isolation Bypass ValveTo allow for in-line inspection, maintenance and removal ofthe valve without service interruption, provide a manuallyoperated shutoff valve on each side of the control valve anda manually operated throttling valve in the bypass line.Heat InsulationIn case of a heat-insulated installation, do not insulate the valvebonnet and take protective measures relative to personalsafety.Hydraulic Test and Line CleaningDuring this operation, the control valve must not be used as anisolating valve. This means that the valve must always beopened before carrying out pressure tests in the process line,cleaning of pipes, etc. Otherwise equipment damage or failureof the seal rings could result.Flow DirectionThe valve must be installed so that the process fluid will flowthrough the valve in the direction indicated by the flow arrowlocated on the body.Globe Style Control Valve with V-LOG TrimAngle Style Control Valve with V-LOG TrimInstructions ET00001 - 2/05Reciprocating Globe and Angle Valves with V-LOG Trim 2


DisassemblyActuator RemovalAccess to the internal components of the body should beaccomplished with the actuator removed. To carry out thisoperation, follow the applicable actuator instructions.Disconnect InstrumentsDisconnect all mechanical connections and any instruments.For valves that use a stem connector connection, loosenthe screws and remove the stem connector. For stems thatare screwed directly into the actuator, unscrew the stem fromthis point.During this operation, make sure that the plug does not turnwhen it is seated. If the plug travel is very small and there isa large amount of plug stem inside the actuator, it may benecessary to remove the yoke nut and lift the actuator sothat the plug is not touching the seat.Prior to disassembly, vent the process pressure and isolatethe valve if necessary.Removing the ActuatorDisconnect all electrical, hydraulic, and pneumatic connectionsfrom and to the actuator. Loosen the yoke nut or attachmentscrews and lift the actuator, making sure that the concentricityand the bonnet thread are not damaged.ChamberOpening Pressurized ChamberThe valve must always be reassembled with new packingset and gaskets.

Maintenance (Figures 3 and 4)Packing BoxTight sealing within the packing box is obtained by compressionof the packing (12). Compression must be achieved by evenlytightening the packing flange nuts (17) on the packing flange(15). Periodic re-tightening of the packing flange nuts is requiredto maintain proper sealing.Be careful not to over tighten the packing as this couldprevent proper operation of the valve. If leakage persists aftermaximum packing compression, then the packing needs tobe changed.Valve with PTFE PackingKevlar/PTFE, carbon/PTFE and pure PTFE packing rings arecut in such a way that they can be replaced without having toseparate the valve plug stem from the actuator stem.Valve with Grafoil PackingTo replace Grafoil packing, it is necessary to separate thevalve plug stem from the actuator stem.1. Remove the packing flange nuts (17) from the packingstuds (16).2. Lift the packing flange (15) and packing follower (14) upalong the valve stem (11).3. By means of a puller, remove the packing (12) being carefulnot to damage the sealing surface of the packing boxor the valve plug stem.4. Replace the packing rings, placing the cut in each ringabout 120° apart from the adjacent ring for PTFE packing.Press rings in one at a time.5. Reassemble the packing follower (14) and the packingflange (15).6. Tighten the packing flange nuts (17) without over compressingthe packing rings.7. Put the valve back into service and check for leakage.Tighten packing flange nuts (17) as required.Repair of PartsPrior to reassemble, examine parts carefully for any scratches,unusual wear, or other damage.Guiding SurfacesGuiding surfaces of the V-LOG restrictor (4), valve plug stemassembly (11), guide bushing (13) and cage retainer (18)when applicable must be checked. If there is only slight wearindications, then use a light abrasive to smooth out guidingsurfaces. Otherwise the factory should be consulted and thepart must be replaced.Seating SurfacesThe lapping procedure should only be conducted by experiencedvalve technicians. Lapping may cause greater damageto the seating surface when improperly done. When indoubt, contact the local Masoneilan factory for assistance.The seat ring seating surface (2) and valve plug seating surface(11) must be completely free of dents, wear, or scratches. Anyseating surface showing signs of slight deterioration should beconsulted with the factory before attempting to touch up. If aslight defect exists on either the seat ring seating surface (2)and valve plug seating surface (11), lapping can be applied perthe following instructions.1. Place seat ring (2) in the body, noting the seating angleis up.2. Assemble the V-LOG restrictor (4) onto the seat ring.3. Spread a fine layer of high quality lapping compound onthe seating surface.4. Assemble the valve plug assembly (11).5. Assemble the bonnet (6) and the guide bushing (13).6. Place an appropriate tool on the valve stem (11) threadto allow for manual rotation.7.Lapping can be repeated, but should be limitedas much as possible so that the seat remainssufficiently narrow to guarantee tightness.8. After lapping, disassemble the parts to clean them andthen reassemble, making sure the seating angles arewithin tolerance.Gasket Seating SurfacesGasket seating surfaces must be free of dents, scratches,and corrosion.Seal Rings and GasketsSpiral-wound gaskets (3) must always be replaced after disassembly.Seal rings (5) can be reused if they are free ofscratches, erosion, corrosion, or other damage.Valve PlugIf the valve plug needs to be replaced see instructions forValve Reassemble.Valve Body - Bridgeman Sealing SurfaceDuring maintenance of the valve, always inspect the body boresurface adjacent to where the Bridgeman Seal (7) is seated. Ifthis surface has been deformed or if there is a groove where theseal seats, the surface should be cleaned and honed prior toreassembling the valve.If the refinishing procedure is unsuccessful, the factory shouldbe consulted for further instructions.Instructions ET00001 - 2/05Reciprocating Globe and Angle Valves with V-LOG Trim 4


If the valve plug or stem (11) needs to be replaced, an entireassembly should be purchased from the factory to ensureproduct strength and integrity. Re-machining of these parts inthe field can seriously impair the mechanical strengths of thevalve plug stem assembly.Cut Away View of Globe Style Valvewith V-LOG TrimThe valve plug is designed as both a pressure retainingbarrier and as a support to withstand loading force providedby the actuator. Machining of this part can be detrimental tothese functions, and may result in damage to the valve andsurrounding equipment.Seal Ring Assembly (If Applicable)To insert the spring-energized seal ring (5) in the valve pluggroove, place it over the conical top of the plug, then pushdown evenly from all sides until the gasket slips into thegroove.
