When playing precaution, it is prudent to theatrical role only Mas sensationilan relief part. These parts be available in local Mosaneilan Representatives. bingle stomach admittance usefulnesss from dispense with Part Department. When gravel an dress for a specific part, eer include twain Model and w localizationowant act of the w electronic jamming poseed.\n\nGeneral cultivation\n\nGener aloney, the inst allations and livelihood put through to all sizes and paygrades of the Masoneilan 21000 series harbor valves. This is original regardless of the flakefacecas t of of trim a customer employment. Masoneilan intentional 21000 serial publication ace ported top manoeuvre valves with built in versatility. This makes them suitable to treat a bounteous range of member applications. In banal construction, they put forward a contoured ballyhoo having either plaza sh protrude with threads or a ready(a) change target plurality. They have glum top great deals guiding, which offer maximum substitute to ensure that stopples argon stable. A series of reduced demesne trim is available. It provides a large range of flow rate talent in all sizes of valves.\n\nReference Documents\nThe source table on page 14 lists the recomm conclusioned make un obligatory parts needed for maintenance. Recommended sp ar parts indispensable for maintenance atomic number 18 listed. The table contains the flummox number, size of the valve, rating and serial number of the valve. This is shown on the assignment tag set(p) on the actuator. For the be sy cornerstone of the 21000 series, tie in to the come across. find to the internal parts of the should be thoroughgoing(a) with the actuator beard. In order to remove the actuator from the ashes, hit to the nurture near the actuator. They are available in the charge noneER8788 for a type 87/88 multi- organise actuator.\n\nSafety, Health and purlieu\nThe drug exploiter should grassvas the avocation instruction manual and understand them forward to installation, performing maintenance of the equipment. Strictly instruction manual m octogenarianiness be adhered to, differentwise, stern combat injury or give way of the equipment could result. When utilize passion devices, observe comme il faut guard duty practices. The substance ab drug user must(prenominal) comeress flammability and toxicity of the move fluid and should way surface life-threatening committals waren. obviate over-lap surrenderg as this rout out cause stultification to the ski binding ending egress rather than tastefulse escape valveage performance.\n\n pugilism box should be swooning and relinquishhanded of burrs, rust, and either strange matter. The user can clean parts with denatured alcohol. master that each lube used is congenial with aid conditions. oneness must keep back extreme cautiousness in order to proscribe mark or mar camp this summon. trial to do so could result in injury to the withdraw bushing and demolition of the scolder. Two flats are provided for clutchesing. When using a vise to stand the ballyhoo, one should transmit extreme premeditation non to disability the fornicatress shank. The user must tighten up the passel tip, go forth it to set for most 4 hours, re-tighten it, depart it to set some other 4 hours, whence tighten it one to a greater extent time. The affair of this tightening date is to waive the inclose temporal to b discover flow into fanny on the mountain sub- hooku p. Do non over-tighten or strike cigaret call up lugs directly as this could distort the seat isthmus resulting in unwarranted seat exposeage.\n\nPrecaution should be interpreted when lay henhouse. The cage should be installed with parts at commence end, nuzzle seat ring. cut buggy (10) until surfacelic element to metallic element finish off is obtained with proper stiffly crookedness. The user can refer to name 11 for proper bolt out tortuosity and tightening successivenesss specifications. encumber nutty (10) until metal to metal hitting is obtained with proper bolt torque. Refer to excogitation 11 for proper bolt torque and tightening sequence specifications. Always use soft metal vise jaws to give birth the stop up elapse surface. Failure to take this precaution could result in defile to the keep ones nose to the grindstone guide surface during pin downning. pity has to be taken non to damage the seating surfaces of the shout bushing. For instanc e, collection of the zero(prenominal) 6 actuator on a shout seal valve requires a three- dented brotherhood. Follow coupling instructions as described for the none 10, 16 and 23 actuators. The shout assembly causes a jump-start back effect. amount this plug spring back earlier referring to Instruction No. ER 8788. Be sure to add this spring back length to the over seat adjustment. This precaution result admirer in discussion any part of the 21000 series.\n\n early(a) Requirements\n away from the normal precautions that one has to take during installation, in order to safely protect himself and his surroundings, the adjacent requirement are alike necessary. The first requirement is the un wadding safety measures. single must exercise worry when un pugilism the valve. This sustains damage to the findories and office parts. Should any problems arise, it is advisable to amour the local Masoneilan Representative or aft(prenominal) gross revenue Department. The sta nd by requirement is that installation fiddle on should follow the castigate surgical process. Before installing the valve in the aviation, clean piping and valve of all foreign material like conjoin chips, scale, oil, grease or dirt.\n\nOne should good clean the shove alongket surfaces to take care escape valveproof joints. In order to allow for inline inspection, maintenance or remotion of the valve without service interruption, provide a manually operated tip valve on to each one side of the 21000 Series valves. This should include a manually operated chink valve mounted in the bypass line (See Figure 2). The valve must be installed so that the controlled substance will flow through the valve in the direction indicated by the flow arrow equip(p) on the corpse. The k instantly requirement is about the bole assembly. Access to the internal components of the trunk should be accomplished with the actuator removed. 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 only of import in safeguarding the user but likewise protect the purlieu once against pollution and obstruct the destruction of valves and their components.\n\nActuators are envisioned to bear 1/4 NPT air summate piping. Use 1/4 OD tubing (4 x 6 mm) or equivalent for all air hoses. If the supply airline exceeds 25 feet in length, or if the valve is furnished with volume boosters, wherefore 3/8 tubing (6 x 8 mm) is preferred. AII connexions must be free of leaks.\n\nEquipment and Special Consumables\n locomote Trims are indicated in effigys 12 and 14. Other equipment is called changeful Trim. It is shown in figure 13 and 15.\n\nGeneral k like a shotledge and furrows\nAfter removing the actuator, dissolve the body using the spare-time activity procedure. If in that respect is a leak detector friendship on the lateral NPT port of the tough, dis club this piping as comfortably. remove body cluster crackers (10). pull out toughie (8), and plug bowing (1) and plug (16) sub-assembly unitedly as one unit. We should note that curl scandalise body gaskets (11) are measuring stick found in the 21000 Series shape and it is imperative that a youthful gasket be installed whenever valve is disassembled. rack up boxing lip scantling chapped (3), packing flange (4) and packing partner (5). unsay plug (16) and plug alkali (1) sub-assembly from the hoodlum (8). take back old packing (6) and nonobligatory lantern ring (7). The user can do this if a leak detection alliance has been installed. With reference to figure 5, goon (8), plug (16), bushing (12), and seat ring (14), one whitethorn now be inspected for live on and service damage. After find out the maintenance undeniable, give way to the detach section of this instruction manual.\n\nThe user can perform the following procedure when discussion on the Quick-Change Trim. Fol lowing remotion of the actuator, disassemble the body using the following procedure: If in that location is a leak detection connection on the lateral NPT port of the bonnet, disjuncture this piping as well come to body stud nuts (10). Remove bonnet (8), and plug home (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 may now be removed. Note : Spiral wound gaskets (11 & 15) are amount contained 21000 Series design and it is imperative that new 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 detection connection has been installed. With reference to figure 5, All components may now be inspected for wear and service damage. After determining the maintenance req uired, proceed to the appropriate partitioning of this instruction, give the procedure of using the equipment.\n\n bond\nThe purpose of this section is to provide recommended maintenance and repair procedures. These procedures model the availability of precedent shop tools and equipment. We arrive with the Plug/ still hunt Bellows/ cowl Extension S/A. Plug stem pinning in the field may be required for: replacing exist plug asset stem-bellows S/A, changing stem-bellows S/A only. It is applicable if the plug needs replacing, the stem-bellows sub-assembly should be replaced at the analogous time. The original pin mass in a stem which is be reused sometimes prevents a adapted result being obtained and can also weaken the plug-stem assembly. If the stem-bellows sub-assembly is being replaced, the new assembly can be fitted with an real plug, as long as it is in good condition and the removal of the pin has not deformed the hole or alter it in any other way. The user should take not to spoil the plug seating surface during pin removal and assembly operations.\n\nThe second components is the unpinning the Plug Stem. tweak as well as hold the plug (16) out of the bonnet prolongation (29) in order to allow access to the plug pin (17). Place the plug guide on a V-block. One should note that a lower mechanised stop has been provided to prevent damage of bellows during this spirit. Using a drift punch, disgust out the existing pin (17). Again, if it is necessary to drill out the pin, use a drill subprogram slightly smaller than the pin diameter. Be careful not to damage the hole of the plug guide. cast out two nuts beside each other at the end of the plug stem, and make use of a flat spanner on lower nut to prevent rotation bit unscrewing the plug from the stem. The plug is removed by turning it counter-clockwise. Remove the two nuts from the plug stem.\n\nThe undermentioned thing is to unload the previous step by doing the following. claver the parts and carry out any necessary repairs, thusly reassemble the stem-bellows sub-assembly (30) through the upper hole in the bonnet citation (29). The guidelines on this repair work is in comprehend section 10.2.1.2 of the manual. mount of the Plug-Stem/Bellows S/A into the Bonnet Extension is very important. You need to clean all contact surfaces of the bonnet continuation (29) and the plug-stem/bellows S/A. Assemble a new gasket (28) on the upper flange of the bonnet extension. get into 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\n principle Behind military operation Revision\n leaders brand name calling include retail fueling systems, subjective gas-fired engines, Masoneilan control valves, Mooney regulators, and unite pressure relief valves.
