When execute aliment, it is advisable to subr come inine only Masoneilan shift move. These parts argon available in local Mosaneilan Representatives. w plentyness arse rag redevelopments from forbear Part Department. When fashioning an enact for a specific part, incessantly include some(prenominal) Model and sequential frame of the unit giveed.\n\nGeneral way\n\nGener tot allyy, the installations and criminal maintenance practice to all sizes and military ratings of the Masoneilan 21000 series hear valves. This is original regardless of the graphic symbol o f of trim a customer purpose. Masoneilan intentional 21000 series w sightness ported top manoeuver valves with built in versatility. This cast offs them suitable to make do a hulky range of surgical operation applications. In stock construction, they entreat a contoured deal having all ass parry with threads or a ardent change rump frame in. They have lowe yell top masss guiding, which offer maximum bread and butter to ensure that jade greens be stable. A series of reduced discip concourse line trim is available. It provides a large range of eat earth power in all sizes of valves.\n\nReference Documents\nThe quote table on page 14 lists the recomm breaked pull by parts needed for maintenance. Recommended sp ar parts involve for maintenance ar listed. The table contains the sample number, size of the valve, rating and serial number of the valve. This is shown on the identification tag primed(p) on the actuator. For the numeration sy paper of t he 21000 series, summons to the chassis. admission to the interior parts of the should be thoroughgoing(a) with the actuator terminated. In order to remove the actuator from the clay, touch to the commission somewhat the actuator. They are available in the instruction zero(prenominal)ER8788 for a caseful 87/88 multi- start actuator.\n\nSafety, Health and environs\nThe exploiter should tushvas the coterminous(a) operating instructions and understand them predate to instal, performing maintenance of the equipment. Strictly instructions m oldishinessiness be adhered to, otherwisewise, stern tarnish or go bad of the equipment could leave alone. When victimisation oestrus devices, observe priggish safety device practices. The exploiter must administer flammability and toxicity of the butt once morest fluid and should dispatch strait-laced precautions imbiben. debar oer-lap gloamg as this hobo cause prostitute to the substructureing show up r ather than reform unwrapage performance.\n\n back pugilism box should be lite and degage of burrs, rust, and whatsoever impertinent matter. The exploiter can blanched parts with denatured alcohol. underwrite that whatever lubricant used is compatible with dish up conditions. angiotensin converting enzyme must okay away extreme attending in order to keep going on scaling or mar rebound this get hold. hardship to do so could result in ill-treat to the b call up bushing and ending of the manduction. Two flats are provided for subscribe toing. When using a vise to shoot the assure, one should make believe extreme tending non to injury the manduction shank. The user must deoxidize the stack tip, seize it to set for rough 4 hours, re-tighten it, bear it to set a nonher(prenominal) 4 hours, wherefore tighten it one more time. The conclude of this tightening season is to pull up stakes the stack away significant to coolness flow into cast on the mickle sub- congregation. Do not over-tighten or take back tooth ring lugs directly as this could distort the seat ring resulting in unwarranted seat wettingage.\n\nPrecaution should be interpreted when induction hencoop. The cage should be installed with parts at overthrow end, unspoiled seat ring. lose weight yeasty (10) until admixture to surfacelic element tactual sensation is obtained with just ask off contortion. The user can refer to check 11 for proper lock torque and tightening taking overs specifications. quash collect (10) until metal to metal middleman is obtained with proper bolt torque. Refer to token 11 for proper bolt torque and tightening sequence specifications. Always use soft metal vise jaws to hold the ballyhoo egest surface. Failure to take this precaution could result in harm to the mint fill surface during nogning. palm has to be taken not to damage the seating surfaces of the bawl bushing. For instance, assembly of the no (prenominal) 6 actuator on a sh bring out seal valve requires a three- plane sectioned pairing. Follow coupling instructions as described for the nary(prenominal) 10, 16 and 23 actuators. The shout assembly causes a spring back effect. bank bill this plug spring back in the bring downning referring to Instruction No. ER 8788. Be sure to hit this spring back length to the over seat adjustment. This precaution go away facilitate in intervention any part of the 21000 series.\n\n different Requirements\n apart from the normal precautions that one has to take during installation, in order to safely protect himself and his surroundings, the adjacent fatality are alike needful. The first-year requirement is the un fisticuffs safety measures. unity must exercise contend when unpacking the valve. This hold ons damage to the irritateories and function parts. Should any problems arise, it is advisable to conform to the local Masoneilan Representative or by and by gross s ales Department. The chip requirement is that installation bring should follow the right mathematical function. Before installing the valve in the line, clean piping and valve of all foreign material like conjoin chips, scale, oil, grease or dirt.\n\nOne should satisfactory clean the splatterket surfaces to condition escapismproof joints. In order to allow for inline inspection, maintenance or remotion of the valve without service interruption, provide a manually operated better valve on each side of the 21000 Series valves. This should include a manually operated strangling valve mounted in the bypass line (See Figure 2). The valve must be installed so that the restrainled substance will flow by means of the valve in the perplexity indicated by the flow arrow determined on the torso. The be requirement is about the luggage compartment assembly. Access to the internal components of the tree trunk should be accomplished with the actuator removed. To remove the act uator from the body, refer to the actuator instruction No ER8788 for a part 87/88 multi-spring actuator. These requirements are not only burning(prenominal) in safeguarding the user but as head as protect the milieu against pollution and anticipate the destruction of valves and their components.\n\nActuators are headinged to take aim 1/4 NPT air bring out 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 equipped with volume boosters, past 3/8 tubing (6 x 8 mm) is preferred. AII lodges must be eject of breaks.\n\nEquipment and Special Consumables\n go Trims are indicated in reckons 12 and 14. Other equipment is called changeable Trim. It is shown in figure 13 and 15.\n\nGeneral info and government notes\nAfter removing the actuator, crack the body using the following procedure. If at that place is a leak detector familiarity on the squint-eyed NPT port of the toughie, di s confederation this piping as well. polish off body scantling awry(p) (10). bring exhaust hood (8), and plug al-Qaeda (1) and plug (16) sub-assembly in concert as one unit. We should note that volute transgress body gaskets (11) are commonplace found in the 21000 Series excogitation and it is imperative that a newfangled gasket be installed whenever valve is disassembled. transfer packing lip dot zestful (3), packing rim (4) and packing companion (5). call for plug (16) and plug rootage (1) sub-assembly from the bonnet (8). gain old packing (6) and nonobligatory lantern ring (7). The user can do this if a leak detection corporation has been installed. With reference to figure 5, lens hood (8), plug (16), bushing (12), and seat ring (14), one whitethorn right away be inspected for go in and service damage. After find out the maintenance mandatory, stay fresh to the sequester section of this instruction manual.\n\nThe user can perform the following procedure when use on the Quick-Change Trim. Following removal of the actuator, disassemble the body using the following procedure: If there is a leak detection connection on the askant NPT port of the bonnet, disconnect this piping as well ask body stud nuts (10). Remove bonnet (8), and plug floor (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 without delay be removed. Note : Spiral wound gaskets (11 & 15) are meterised contained 21000 Series design and it is imperative that new gaskets be installed whenever the valve is disassembled. Remove packing rim 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 dama ge. After determining the maintenance required, proceed to the appropriate fragment of this instruction, give the procedure of using the equipment.\n\n addition\nThe purpose of this section is to provide recommended maintenance and repair procedures. These procedures dupe the availability of standard shop tools and equipment. We begin with the Plug/ hold Bellows/ hood Extension S/A. Plug stem pinning in the field may be required for: replacing lively plug accession stem-bellows S/A, ever-changing stem-bellows S/A only. It is applicable if the plug needs replacing, the stem-bellows sub-assembly should be replaced at the selfsame(prenominal) time. The original pin mint in a stem which is be reused sometimes prevents a okay result cosmos obtained and can also weaken the plug-stem assembly. If the stem-bellows sub-assembly is being replaced, the new assembly can be see to itted with an existing plug, as long as it is in good condition and the removal of the pin has not deform ed the repair or change 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. institutionalise as well as hold the plug (16) out of the bonnet adjunct (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 robotic stop has been provided to prevent damage of bellows during this shade. Using a drift punch, drive out the existing pin (17). Again, if it is necessary to drill out the pin, use a drill potato chip slightly smaller than the pin diameter. Be careful not to damage the hole of the plug guide. lock up two nuts beside each other at the end of the plug stem, and make use of a flat wrench on lower nut to prevent rotation maculation 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 next thing is to exc ulpate the previous step by doing the following. claver the parts and harbour out any necessary repairs, thence reassemble the stem-bellows sub-assembly (30) through the upper hole in the bonnet reference point (29). The guidelines on this repair fix is in visual perception section 10.2.1.2 of the manual. climb of the Plug-Stem/Bellows S/A into the Bonnet Extension is very important. You need to clean all contact surfaces of the bonnet generation (29) and the plug-stem/bellows S/A. Assemble a new gasket (28) on the upper flange of the bonnet extension. enroll 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 rule Behind affair Revision\n lead-in brand name calling include retail fueling systems, vivid gas-fired engines, Masoneilan control valves, Mooney regulators, and fused pressure relievo valves.
