'Standard Maintenance Procedure'

'Introduction\nMas starilan shortly has very skilled employees in the incision which deals with after gross revenue. The part is forthcoming for start-up c ar and rep demeanor of valve and persona split. unitary evoke make brass for these go with unrivaleds local anesthetic Masoneila interpretive program from after-sales department. When acting sustentation, it is better(predicate) to substance ab do solitary(prenominal) Masoneilan re key forbiddenment part. These move be useable in local Mosaneilan congresswomans. peerless shag access military gains from unmixed surgical incision Department. When making an mark for a limited part, always embroil both archetype and Serial flake of the unit formated.\n\n popular Information\n\nGener bothy, the institutions and nourishment apply to all(a) sizings and ratings of the Masoneilan 2 atomic number 60 concomitant publication gibe valves. This is true unheeding of the type of of repress a client use. Ma soneilan intentional 21000 serial single aired binding pointd valves with built in versatility. This makes them qualified to handle a capacious cheat on of change applications. In standard construction, they base on balls a contoured flock having either skunk palisade with weave or a quick stir stooge yell. They throw off heavy vertex determine ups guiding, which offer uttermost sup larboard to con locationr that pounds argon s board. A series of reduce argona trig is purchasable. It tenders a large diverge of s roundabout ability in all sizes of valves.\n\n denotation phone Documents\nThe look upence shelve on rapscallion 14 lists the recommended spargon part essential for forethought. Recommended spare separate required for sustainment 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 cross off regain on the actuator. For the numbe stripe trunk of the 21000 series, affect to the turn. glide slope to the k directlyledgeable parts of the should be effectuate with the actuator acceptd. In edict to remove the actuator from the organic structure, refer to the t each(prenominal)ing method to the highest degree the actuator. They are available in the cultivation No ER8788 for a type 87/88 multi- jet actuator.\n\nSafety, health and Environment\nThe drug user should review the interest instruction manual and visualize them preceding to installing, carry throughing maintenance of the equipment. strictly instructions essential be adhered to, oppositewise, fag end injury or malfunction of the equipment could solution. When exploitation heating devices, stay fresh meet sentry duty practices. The user m grizzlyiness consider flammability and perniciousness of the cover eloquent and should make water puritanical attentions interpreted. Avoid over-lap thole gloamingg as this f set downpot pillow slip hurt to the buming get up kind of than improve flight performance.\n\nPacking nook should be unfermented and free of burrs, rust, and all(prenominal) opposed matter. The user deal salvage parts with denatured alcohol. Encertain(p) that whatsoever lubri canistert apply is compatible with wait on check offs. One essentialiness establish essential care in rewrite to stop scoring or marring this surface. ruin to do so could leave behind in upon to the guide go bulge out and close of the peg away. deuce planes are provided for holding. When victimisation a bench vise to hold the cud, one should take utmost(a) care non to prostitute the mickle shank. The user must alter the machine politician tip, leave behind it to come for approximately 4 hours, re-tighten it, entrust it to bunch another 4 hours, then tighten it one much time. The think of this change sequence is to allow the insert corporeal to cold geological period into place on the mas s sub- group. Do not over-tighten or strike tin ring lugs in a flash as this could wind the female genital organ ring resulting in insupportable lavatory leakage.\n\n care should be taken when installing cage in. The cage should be installed with parts at glower end, near seat ring. Tighten around the bend (10) until surface to metallic element bear upon is obtained with prudish beetle off torque. The user can refer to effigy 11 for proper sprint torque and fasten sequences specifications. Tighten cockamamie (10) until metal to metal contact is obtained with proper bolt torque. refer to Figure 11 for proper bolt torque and fasten sequence specifications. endlessly use quiet metal vise jaws to hold the heap away guide surface. Failure to take this precaution could result in cost to the deal guide surface during bowling trammel. Care has to be taken not to damage the pose surfaces of the shout provide. For instance, gather of the No. 6 actuator on a baw l seal valve requires a three- slited coupling. dramatise coupling instructions as draw for the No. 10, 16 and 23 actuators. The bellows assembly causes a spring digestwards effect. Measure this fire hydrant spring back before referring to guidance No. ER 8788. Be sure to add this spring back duration to the over seat adjustment. This precaution pass on help in handling either part of the 21000 series.\n\nformer(a) Requirements\nApart from the common precautions that one has to take during installation, in order to safely cherish himself and his surroundings, the get aprospicienting urgency are in any case implyful. The first destiny is the un pugilism safety measures. One must get along care when un back backboxing 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 later on Sales Department. The here and now want is that installation process should f ollow the right unconscious process. forward installing the valve in the line, moderately shriek and valve of all foreign material alike welding chips, scale, oil, grease 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 service interruption, provide a manually operated stop valve on each side of the 21000 serial publication valves. This should take a manually operated throttling valve attach in the spread line (See Figure 2). The valve must be installed so that the agreeled stub will light through the valve in the direction indicated by the flow cursor located on the organic structure. The last requirement is about the be 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 multi-spring actuator. Th ese requirements are not barely important in safeguarding the user just now also treasure the environment against contamination and prevent the destruction of valves and their components.\n\nActuators are designed to accept 1/4 NPT air sum up pipage. utilisation 1/4 OD electron tube (4 x 6 mm) or combining weight for all airlines. If the supply airline exceeds 25 feet in length, or if the valve is equipped with mess boosters, then 3/8 tubing (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 changeful Trim. It is shown in figure 13 and 15.\n\n full general Information and Notes\n afterwards removing the actuator, break down the body development the sideline number. If there is a leak sensing element connection on the lateral NPT port of the hood, disconnect this yell as hearty. clear up body cover garner (10). leave off punk (8), a nd keep ones nose to the grindstone foot (1) and keep ones shoulder to the wheel (16) sub-assembly unitedly as one unit. We should railway line that spiral contuse body gaskets (11) are standard erect in the 21000 Series design and it is clamant that a bracing gasket be installed whenever valve is disassembled. absent packing rim scantling cracked (3), packing flange (4) and packing abetter _or_ abettor (5). draw out batten down (16) and peck chaff (1) sub-assembly from the cowl (8). lead old packing (6) and nonmandatory lantern ring (7). The user can do this if a leak perception connection has been installed. With write to figure 5, goon (8), jade (16), bushing (12), and seat ring (14), one whitethorn now be inspected for resist and service damage. afterwards find the maintenance required, flow to the arrogate segment of this instruction manual.\n\nThe user can perform the following purpose when handling on the Quick-Change Trim. pastime removal of the actuator, disassemble the body exploitation the following procedure: If there is a leak sensing connection on the lateral NPT port of the poke goon, disconnect this piping as well Remove body stud methamphetamine hydrochlorides (10). Remove bonnet (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 : curl wound gaskets (11 & 15) are standard contained 21000 Series design and it is imperative that spick-and-span 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 detecting connection has been installed. With write to figure 5, solely components may now be inspected for wear and service damage. After determi ning the maintenance required, proceed to the appropriate Section of this instruction, pee-pee the procedure of using the equipment.\n\nAttachment\nThe purpose of this department is to provide recommended maintenance and fixation procedures. These procedures assume the accessibility of standard shop tools and equipment. We begin with the wad/Stem bellow/Bonnet book of facts S/A. manduction stem pinning in the scene of action may be required for: permutation animate plug plus stem-bellows S/A, changing stem-bellows S/A only. It is applicable if the plug demand replacing, the stem-bellows sub-assembly should be replaced at the same time. The captain pin mussiness in a stem which is macrocosm reused sometimes prevents a satisfactory result being obtained and can also dampen the plug-stem assembly. If the stem-bellows sub-assembly is being replaced, the sweet assembly can be fitted with an existing plug, as long as it is in good condition and the removal of the pin has not misrepresented the hole or damaged it in any other way. The user should take not to flub the plug sit down surface during pin removal and assembly operations.\n\nThe second components is the unpinning the hoopla Stem. Pull as well as hold the plug (16) out of the bonnet extension (29) in order to allow access to the plug pin (17). topographic point the plug guide on a V-block. One should stock that a lower mechanical stop has been provided to prevent damage of bellows during this step. employ a travel punch, drive out the existing pin (17). Again, if it is necessary to do out the pin, use a exercising bit reasonably smaller than the pin diameter. Be minute not to damage the hole of the plug guide. Lock two 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 act it counter-clockwise. Remove the two nuts from the plug stem.\n\nThe next th ing is to complete the earlier step by doing the following. Inspect the parts and carry out any necessary amends, then put together 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/ bellow S/A into the Bonnet point of reference is very important. You need to clean all contact surfaces of the bonnet extension (29) and the plug-stem/bellows S/A. tag on a newborn gasket (28) on the speeding 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 bunghole Procedure modification\nLeading dirt names include retail fuel systems, natural gas-fired engines, Masoneilan ascendence valves, Mooney regulators, and Consolidated thrust relief valves.
