1. Valve Body:
Set control valve in the horizontal line of piping in an accessible location with the arrow on the side of the valve body in the direction of fluid flow. Upright positioning of control valve is preferable for ease of maintenance. Work spaces around the control valve body are to be provided sufficiently for easy removal or reinstall of parts during maintenance. Caution: Piping systems are to be flushed thoroughly with sufficient amount of water or air prior to installation of control valve bod...
2. Strainer:
To be installed between the inlet block valve and control valve. In case other strainer is installed upstream line, this strainermay be deleted.
3. Isolation valves:
Stop valves (and gauges if necessary) in inlet and outlet lines are to be installed to provide means for checking, adjustment or emergency maintenance during operation.
1. Isolation:
Close inlet and outlet stop valves.
2. Movement check:
Check if control valve responds properly through rated travel in relation to the changes in operating pressure in the diaphragm. Rated travel is shown by the position of the indicator on the valve stem relative to the indicator plate scale on the yoke.
3. Manual operation:
Manually operate control valve fitted with manual operating devices through the rated travel range to check freedom of movement. Return manual operating devices to its stand-by position.
To reduce maintenance time refer to proper drawing and follow the steps shown below for applicable maintenance.
a. Preparation:
Close inlet and outlet stop valve and relieve all pressure from piping involved. Remove all compression from adjusting spring <31>.
b. Disengagement of plug from the seat ring:
[Direct Type] Relieve air pressure from diaphragm of actuator. Remove tubing from the diaphragm casing <37>. [Reverse Type] Supply sufficient air to the actuator diaphragm to keep plug <13> from touching seat ring <12> while disengaging valve stem <26> from the actuator stem <28>.
c. Separation of stems:
Loosen hex. nut <17>. Use wrench on stem flats and turn valve stem <26> out of actuator (upper) stem until both stems are separated. Remove the tubing from diaphragm case1 <35> for Air to Open (Reverse) Type Valves.
a. Removal of actuator:
Remove actuator from valve body assembly as previously described in disassembly of diaphragm actuator from valve body assembly.
b. Removal of bonnet:
Remove bonnet hex. Nuts <4>. Lift off bonnet assemblyincluding plug <13> from the body <1>.
c. Disassembly of bonnet and valve body:
Remove plug<13>, packing follower <7> and old packing set <16>. Remove bonnet gasket <14>, lantern ring [Fig 1 & 3] or cage [Fig 2 & 4] <2>, seat ring <12> and seat gasket <11>. If necessary, remove seat ring by forcing a wooden dowel into seat bore and lifting.
a. Cleaning of component parts:
Clean all parts thoroughly. Polish stem with crocus cloth. It should be smooth and free of scratches especially in the packing area. Use approved non-residue forming solvent for cleaning. Wipe dry with clean cloth.
b. Inspection:
Inspect all parts and replace any excessively worn out or damaged part.
c. Replacement of parts:
Install a new graphite packing set as shown on packing installation sketch above Fig. See previous section on renewing packing set. The packing follower <7> has a long wearing life which under normal usage should not require replacement. However, if damaged or worn out, the packing follower and/or the bonnet <3> must be replaced. The bonnet gasket <14> and seat gasket <11> should be replaced each time the valve body assembly is disassembled for cleaning.
a. Valve body:
Insert seat ring <12>, with raised face upward, into the bore of the body and place the lantern ring <2> [Fig 1 & 3] or the cage <2> [Fig 2 & 4] on the seat ring <12>. Seat ring must be correctly seated in place.
b. Bonnet assembly:
Applying light pressure and turning motion assemble plug stem <13> into the bonnet assembly <3>. Fix stud bolts to the valve body flange.
c. Bonnet on valve body:
Place bonnet gasket <14> in the body recess and install the bonnet assembly on top of the valve body. Apply hex. nuts <4> to stud bolts <5> and tighten firmly and evenly until the bonnet and valve body flanges almost touch each other.
a. Adjustment of actuator spring preload:
Connect controlled air line to diaphragm case connector. Supply 0.4kg/cm² (6psig) of air pressure to the diaphragm of actuator. Adjust the preload of actuator spring <31> by turning adjusting nut <19> until indicator <18> just starts to move at an air pressure of approx. 0.4 kg/cm² (6 psig). Actuator spring preload adjustment can be made either with or without pressure in valve body. Once correct adjustment is made, no further adjustment is necessary.
b. “Close” position:
Supply 2.0 kg/cm² (30psig) of operating pressure to actuator diaphragm. Check and confirm if the valve fully closes at this pressure.
c. Connection of tubings:
Reduce air pressure from actuator diaphragm and reconnect operating medium tubing from control pilot, instrument, or loading device to the diaphragm case.
Nov 12, 2017 · I bought three Aladdin autovents, fitted them to the leftward radiator cap, but they won't vent air when fitted. Do I need to unscrew the internal cartridge for air to vent out?
