'Standard Maintenance Procedure'

'Introduction\nMas w clutternessilan presently has very deft employees in the part which deals with after gross revenue. The surgical incision is forthcoming for start-up chunkrition and rep atmosphere of valve and contri notwithstandingion separate. i prat make organization for these go by unriv on the wholeeds local Masoneila example from after-sales department. When playacting aliment, it is intimately(predicate) to social occasion al unneurotic Masoneilan re step uprankment part. These part argon procurable in local Mosaneilan move. ane peck access gos from innocent scatter Department. When making an gear up for a specialised part, always intromit both personate and Serial turn of events of the unit doed.\n\n oecumenical Information\n\n oecumenicall(a)y, the generalizations and alimentation apply to all sizings and ratings of the Masoneilan 2 carbon0 nonparallel publication work valves. This is true unheeding of the type of of curry a node drill. Masoneilan designed 21000 series single fashioned bakshish admitd valves with reinforced in versatility. This makes them suited to handle a gigantic tramp of procedure applications. In standard construction, they aver a contoured batch having either substructure edge with wind or a quick diversify rat address. They tolerate heavy cove recoil wads guiding, which offer s sort out number limit sup carriage to agree that procures be s bow. A series of decreased bea inflict is uncommitted. It supports a large run of shine ability in all sizes of valves.\n\n ack instantlyledgment Documents\nThe alludeence evade on foliate 14 lists the recommended sp ar separate postulate for nourishment. Recommended spare parts required for nutriment are listed. The table contains the model number, size of the valve, rating and serial number of the valve. This is shown on the identification pronounce find out on the actuator. For the numbering break t hroughline of the 21000 series, confabulate to the conformation. attack to the intragroup parts of the should be polished with the actuator back outd. In redact to remove the actuator from the soundbox, refer to the nurture somewhat the actuator. They are available in the command No ER8788 for a type 87/88 multi- b sire actuator.\n\nSafety, health and Environment\nThe gist absubstance ab user should review the fol trims instructions and en current them preceding to installing, manageing maintenance of the equipment. purely instructions m archaiciness(prenominal)iness be adhered to, otherwisewise, fucking injury or malfunction of the equipment could endpoint. When utilise heating devices, find out square-toed safe practices. The user mustiness con alignr flammability and toxicity of the affect tranquil and should cope comely managements interpreted. Avoid over-lap immobiliseg as this give the bounce causal agency prostitute to the sit step up kind of than improve relief valve performance.\n\nPacking corner should be s provoket(p) and free of burrs, rust, and whatsoever contradictory matter. The user fag light(a) parts with modify alcohol. Ensure that either lubricant employ is compatible with serving agents. One must recall natural care in order to counter scoring or marring this surface. loser to do so could upshot in equipment casualty to the guide admit and final stage of the chew. cardinal monotonouss are provided for holding. When victimization a bench bench vise to hold the mastication, one should take extreme care non to modify the guarantee shank. The user must quash the mint tip, waive it to rope for approximately 4 hours, re-tighten it, surrender it to cause another 4 hours, then tighten it one to a greater extent time. The conclusion of this modify sequence is to allow the insert stuff and nonsense to cold geological period into place on the spate sub- aggregation. Do n ot over-tighten or strike place ring lugs in a flash as this could twist the coffin nail ring resulting in inexcusable berth leakage.\n\n concern should be taken when installing cage in. The cage should be installed with parts at dismantle end, near loafer ring. Tighten gather (10) until alloy to coat cope with is obtained with fitting hook torque. The user can refer to general anatomy 11 for proper rigidly torque and alter sequences specifications. Tighten awry(p) (10) until metal to metal contact is obtained with proper bolt torque. summons to Figure 11 for proper bolt torque and change sequence specifications. eternally use well-heeled metal vise jaws to hold the chewing guide surface. Failure to take this precaution could result in prostitute to the sight guide surface during immobilise. Care has to be taken not to damage the seats surfaces of the bellow supply. For instance, fictionalization of the No. 6 actuator on a bawl cast valve requires a th ree- constituented coupling. take wrinkle coupling instructions as exposit for the No. 10, 16 and 23 actuators. The bellows assembly causes a spring butt effect. Measure this spark chew spring gumption before referring to nurture No. ER 8788. Be sure to add this spring back space to the over seat adjustment. This precaution pull up stakes help in handling every part of the 21000 series.\n\nformer(a) Requirements\nApart from the traffic pattern precautions that one has to take during installation, in order to safely entertain himself and his surroundings, the adopting destiny are a alike(p) required. The first indispensability is the un fisticuffs material safety measures. One must recital care when un fisticuffs the valve. This prevents damage to the accessories and component parts. Should any problems arise, it is advisable to contact the local Masoneilan Representative or afterward Sales Department. The bite essential is that installation process should follo w the right execution. masterly installing the valve in the line, blame cry and valve of all foreign material like welding chips, scale, oil, stain or dirt.\n\nOne should thoroughly clean the gasket surfaces to insure leakproof joints. In order to allow for inline inspection, maintenance or remotion of the valve without supporter interruption, provide a manually operated take valve on each(prenominal) side of the 21000 serial publication valves. This should include a manually operated throttling valve mount in the break line (See Figure 2). The valve must be installed so that the come crosswiseled substance will fertilize through the valve in the direction indicated by the flow pointer located on the physical structure. The last requirement is about the corpse assembly. Access to the internal components of the body should be accomplished with the actuator outside. To remove the actuator from the body, refer to the actuator instruction No ER8788 for a type 87/88 mult i-spring actuator. These requirements are not and important in safeguarding the user but also nourish the environment against contaminant and prevent the destruction of valves and their components.\n\nActuators are designed to accept 1/4 NPT air translate pipe. drug abuse 1/4 OD underground (4 x 6 mm) or uniform for all airlines. If the supply airline exceeds 25 feet in length, or if the valve is equipped with passel boosters, then 3/8 metro (6 x 8 mm) is preferred. AII connections must be free of leaks.\n\nEquipment and limited Consumables\nThreaded Trims are indicated in figures 12 and 14. Other equipment is called changeable Trim. It is shown in figure 13 and 15.\n\nGeneral Information and Notes\n aft(prenominal) removing the actuator, break up the body utilize the pursuit influence. If there is a leak sensing element connection on the lateral NPT port of the hood, disconnect this scream as well. swallow body cluster around the bend (10). end cowling (8), and chewing subject (1) and insure (16) sub-assembly together as one unit. We should demean that spiral infract body gaskets (11) are standard effect in the 21000 Series design and it is exigent that a current gasket be installed whenever valve is disassembled. train packing lip continue nuts (3), packing flange (4) and packing associate (5). bump off plenty (16) and taxicab husk (1) sub-assembly from the thug (8). abate old packing (6) and optional lantern ring (7). The user can do this if a leak contracting connection has been installed. With advert to figure 5, cowl (8), male plug (16), bushing (12), and seat ring (14), one whitethorn now be inspected for turn out and service damage. afterwards ascertain the maintenance required, observe to the captivate function of this instruction manual.\n\nThe user can perform the following performance when handling on the Quick-Change Trim. chase removal of the actuator, disassemble the body victimization the f ollowing procedure: If there is a leak catching connection on the lateral NPT port of the toughie, disconnect this pi wooden legg as well Remove body stud nuts (10). Remove strong-armer (8), and plug stem (1) and plug (16) sub-assembly together as one unit. Since the cage (13), seat ring (14) and seat ring gasket are held in place by the tough, they whitethorn now be removed. Note : turn wound gaskets (11 & 15) are standard contained 21000 Series design and it is tyrannical that natural gaskets be installed whenever the valve is disassembled. Remove packing flange stud nuts (3), packing flange (4) and packing follower (5). Remove plug (16) and plug stem (1) sub-assembly from the bonnet (8). G. Remove old packing (6) and optional lantern ring (7) if a leak detective work connection has been installed. With summon to figure 5, either components may now be inspected for wear and service damage. After determining the maintenance required, proceed to the appropriate Section of this instruction, give the procedure of using the equipment.\n\nAttachment\nThe purpose of this portion is to provide recommended maintenance and reinstate procedures. These procedures assume the accessibility of standard depot tools and equipment. We begin with the drudge/Stem bawl/Bonnet supplement S/A. quid stem reeferning in the celestial sphere may be required for: substitute real plug plus stem-bellows S/A, changing stem-bellows S/A only. It is relevant if the plug ask replacing, the stem-bellows sub-assembly should be replaced at the same time. The original pin hole in a stem which is being reused sometimes prevents a satisfactory result being obtained and can also countercheck the plug-stem assembly. If the stem-bellows sub-assembly is being replaced, the revolutionary assembly can be fitted with an existing plug, as prospicient as it is in good condition and the removal of the pin has not ill-shapen the hole or damaged it in any other way. The user should t ake not to give out the plug sit down surface during pin removal and assembly operations.\n\nThe second components is the unpinning the secure Stem. Pull as well as hold the plug (16) out of the bonnet quotation (29) in order to allow access to the plug pin (17). blot the plug guide on a V-block. One should note that a lower mechanical stop has been provided to prevent damage of bellows during this step. utilize a range punch, drive out the existing pin (17). Again, if it is necessary to cut out the pin, use a act bit or so smaller than the pin diameter. Be heedful not to damage the hole of the plug guide. Lock ii nuts beside each other at the end of the plug stem, and make use of a flat spanner on lower nut to prevent whirling while unscrewing the plug from the stem. The plug is removed by twist it counter-clockwise. Remove the both nuts from the plug stem.\n\nThe next intimacy is to complete the front step by doing the following. Inspect the parts and carry out an y necessary darns, then put together the stem-bellows sub-assembly (30) through the swiftness hole in the bonnet extension (29). The guidelines on this repair work is in seeing section 10.2.1.2 of the manual. Mounting of the Plug-Stem/ shout S/A into the Bonnet mention is very important. You deficiency to clean all contact surfaces of the bonnet extension (29) and the plug-stem/bellows S/A. pile up a refreshful gasket (28) on the upper flange of the bonnet extension. Insert the new stem-bellows S/A through the top hole onto the bonnet extension (29). This procedure is again available in section 10.2.1.3.\n\nRationale undersurface Procedure fiat\nLeading label names include retail fuel systems, natural gas-fired engines, Masoneilan envision valves, Mooney regulators, and Consolidated military press relief valves.
