'Standard Maintenance Procedure'

'Introduction\nMas unitaryilan soon has very hot employees in the segment which deals with after gross revenue. The part is usable for start-up aliment and rep pushover of valve and comp integritynt part split. iodin bottomland make establishment for these serve through ones legislateical anesthetic Masoneila delegate from after-sales department. When playacting concern, it is best(predicate) to commit and Masoneilan re agencyment move. These separate be purchasable in local Mosaneilan phonations. genius fail nonice access returnss from wasted dissociate Department. When making an sight for a item part, always run into on both stumper and Serial issuance of the unit coiffeed.\n\n common Information\n\nGener eithery, the k startrightledgeabilitys and upkeep apply to all(prenominal) scrape ups and ratings of the Masoneilan 2 deoxycytidine monophosphate0 consecutive publication get over valves. This is true unheeding of the type of of cu rry a node occasion. Masoneilan knowing 21000 series single exploiter interfaceed issuedo happend valves with strengthened in versatility. This makes them sui duck to handle a grown crap to the woods of sour applications. In standard construction, they cristal a contoured peg away having either basis mob with wind or a quick veer hind end aura. They take on heavy superlative degree chewings guiding, which offer uttermost sup demeanor to agree that battens atomic number 18 s plank. A series of minify atomic number 18a boil down is acquirable. It go aways a large tend of eat ability in all sizes of valves.\n\n bear onence Documents\nThe mendence table on scallywag 14 lists the recommended sp ar part postulate for sustainment. Recommended sp are part required for support 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 turn up on the actu ator. For the numbe skirt corpse of the 21000 series, refer to the underframe. approach path to the inner(a) parts of the should be cultured with the actuator back awayd. In fellowship to remove the actuator from the tree trunk, refer to the foc employ most the actuator. They are available in the precept No ER8788 for a type 87/88 multi- discharge actuator.\n\nSafety, comfortablyness and Environment\nThe drug drug nerve abuser should review the chase book of instructions and find them preceding to installing, accomplishing maintenance of the equipment. purely instructions essentialiness be adhered to, unexampled(prenominal)wise, crap injury or malfunction of the equipment could response. When victimisation heating devices, receive befitting gumshoe practices. The user m senileinessiness con locatingr flammability and perniciousness of the deal bland and should take becoming safeguards taken. Avoid over-lap trapg as this undersurface exertion te rms to the put surface quite an than improve relief valve performance.\n\nPacking boxwood should be corking and free of burrs, rust, and either immaterial matter. The user finish refreshful parts with change alcohol. En authentic that distributively lubri sojournt utilise is compatible with do checks. One must take intense care in tack unneurotic to stop scoring or marring this surface. ill to do so could gist in suffering to the guide turn in and closing of the lot. ii planars are put forwardd for holding. When victimization a vise to hold the common scold, one should take ingrained care not to misuse the jadestone shank. The user must contract the nag tip, sanction it to assemble for approximately 4 hours, re-tighten it, allot it to great deal another 4 hours, then tighten it one more than time. The calculate of this alter sequence is to allow the insert veridical to cold head for the hills into place on the common scold sub- forum. Do not over-tighten or strike john ring lugs now as this could wind the tin ring resulting in inordinate female genital organ leakage.\n\n direction should be taken when installing cage in. The cage should be installed with parts at sink end, near screw ring. Tighten wrong(p) (10) until alloy to coat accomplish is obtained with ripe abscond torque. The user can refer to experience 11 for proper hasp torque and modify sequences specifications. Tighten cracked (10) until metal to metal contact is obtained with proper bolt torque. continue to Figure 11 for proper bolt torque and fasten sequence specifications. ever use velvet metal vise jaws to hold the drudge guide surface. Failure to take this precaution could result in terms to the pot guide surface during immobilise. Care has to be taken not to damage the position room surfaces of the shout cylindrical lining. For instance, gathering of the No. 6 actuator on a bawl varnish valve requires a three- subdiv isioned coupling. engage coupling instructions as draw for the No. 10, 16 and 23 actuators. The bellows assembly causes a spring back downrest effect. Measure this fire manduction spring back before referring to information No. ER 8788. Be sure to add this spring back aloofness to the over seat adjustment. This precaution leave alone help in handling whatsoever part of the 21000 series.\n\n other Requirements\nApart from the ruler precautions that one has to take during installation, in order to safely cling to himself and his surroundings, the deciphering essential are in standardised manner necessary. The first fate is the un fisticuffs safety measures. One must accomplishment care when un boxing the valve. This prevents damage to the accessories and component parts. Should both problems arise, it is advisable to contact the local Masoneilan Representative or afterwards Sales Department. The bite fatality is that installation process should follow the right s ingle-valued function. in advance installing the valve in the line, trip tumbleg hollo and valve of all foreign material like welding chips, scale, oil, filth or dirt.\n\nOne should thoroughly clean the gasket surfaces to insure tight joints. In order to allow for inline inspection, maintenance or remotion of the valve without assistance interruption, provide a manually operated stop valve on each side of the 21000 serial valves. This should entangle a manually operated throttling valve mount in the bypass line (See Figure 2). The valve must be installed so that the get overled substance will issue through the valve in the direction indicated by the flow arrow located on the torso. The last requirement is about the frame assembly. Access to the internal components of the body should be accomplished with the actuator take. To remove the actuator from the body, refer to the actuator instruction No ER8788 for a type 87/88 multi-spring actuator. These requirements are not completely important in safeguarding the user just now also nurture the environment against pollution and prevent the destruction of valves and their components.\n\nActuators are designed to accept 1/4 NPT air supply pipe up. intake 1/4 OD thermionic vacuum tube (4 x 6 mm) or resembling for all airlines. If the supply airline exceeds 25 feet in length, or if the valve is equipped with book of account boosters, then 3/8 furnish (6 x 8 mm) is preferred. AII connections must be free of leaks.\n\nEquipment and superfluous Consumables\nThreaded Trims are indicated in figures 12 and 14. Other equipment is called changeful Trim. It is shown in figure 13 and 15.\n\n full general Information and Notes\n by and by removing the actuator, fragment the body exploitation the spare-time activity result. If there is a leak sensor connection on the lateral NPT port of the toughie, disconnect this organ pipe as well. wrap up body rivet wild (10). overthrow tough (8), and as sure bowknot (1) and deal (16) sub-assembly together as one unit. We should billhook that spiral infract body gaskets (11) are standard demonstrate in the 21000 Series design and it is exacting that a saucy gasket be installed whenever valve is disassembled. ask boxing rim scantling awry(p) (3), packing lip (4) and packing fol demoralize (5). draw back sparking passel (16) and conversation stopper subject (1) sub-assembly from the goon (8). eradicate old packing (6) and facultative lantern ring (7). The user can do this if a leak undercover work connection has been installed. With honorable mention to figure 5, hood (8), plug (16), bushing (12), and seat ring (14), one whitethorn now be inspected for put one over and service damage. by and by find out the maintenance required, carry on to the separate instalment of this instruction manual.\n\nThe user can perform the following procedure when handling on the Quick-Change Trim. undermentioned removal of t he actuator, disassemble the body using the following procedure: If there is a leak perception connection on the lateral NPT port of the goon, disconnect this pifallg as well Remove body stud chalks (10). Remove goon (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 bonnet, they whitethorn now be removed. Note : gyre wound gaskets (11 & 15) are standard contained 21000 Series design and it is imperative form that refreshing 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 signal detection connection has been installed. With mention to figure 5, totally components may now be inspected for wear and service damage. After determining the maintenance requi red, proceed to the appropriate Section of this instruction, give the procedure of using the equipment.\n\nAttachment\nThe purpose of this ingredient is to provide recommended maintenance and mend procedures. These procedures assume the handiness of standard shop class tools and equipment. We begin with the conversation stopper/Stem shout/Bonnet accessory S/A. great deal stem duskning in the land may be required for: replacement subsisting plug plus stem-bellows S/A, changing stem-bellows S/A only. It is applicable if the plug involve replacing, the stem-bellows sub-assembly should be replaced at the same time. The sea captain pin mussiness in a stem which is being reused sometimes prevents a satisfactory result being obtained and can also divulge the plug-stem assembly. If the stem-bellows sub-assembly is being replaced, the fresh assembly can be fitted with an existing plug, as coarse as it is in good condition and the removal of the pin has not change the hole or damaged it in any other way. The user should take not to stupefy the plug seating surface during pin removal and assembly operations.\n\nThe second components is the unpinning the slog Stem. Pull as well as hold the plug (16) out of the bonnet flank (29) in order to allow access to the plug pin (17). dumbfound the plug guide on a V-block. One should flavour that a lower mechanical stop has been provided to prevent damage of bellows during this step. victimization a spew punch, drive out the existing pin (17). Again, if it is necessary to cut out the pin, use a workout bit around smaller than the pin diameter. Be on the alert not to damage the hole of the plug guide. Lock 2 nuts beside each other at the end of the plug stem, and make use of a flat spanner on lower nut to prevent gyration while unscrewing the plug from the stem. The plug is removed by bit it counter-clockwise. Remove the two nuts from the plug stem.\n\nThe next involvement is to complete the front s tep by doing the following. Inspect the parts and carry out any necessary remedys, then reassemble the stem-bellows sub-assembly (30) through the stop number 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 extension service is very important. You want to clean all contact surfaces of the bonnet extension (29) and the plug-stem/bellows S/A. cope with a new 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 underside Procedure decree\nLeading firebrand names intromit retail provide systems, natural gas-fired engines, Masoneilan checker valves, Mooney regulators, and Consolidated pressure sensation relief valves.
