1. Safety Information
Important - Please Read Before Installation
The 73000 Series control valves instructions contain DANGER, WARNING, and CAUTION labels, where
necessary, to alert you to safety related or other important information.Read the instructions carefully
before installing and maintaining your control valve. DANGER and WARNING hazards are related to
personal injury. CAUTION
hazards involve equipment or property damage. Operation of damaged equipment
can, under certain operational conditions, result in degraded process system performance that can lead to
injury or death. Total compliance with all DANGER, WARNING, and CAUTION notices is required for safe
operation.
This is the safety alert symbol. It alerts you to potential personal injury hazards. Obey all safety messages that
follow this symbol to avoid possible injury or death.
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in serious injury.

2. Installation
Prior to installing the valve, clean the pipeline of all foreign matter such as dirt, spatters (welding chips), scale,
oil or grease. Install the valve in the pipeline so that the fluid flows in the direction indicated by the flow arrows
attached to the body, or the fluid flows from "IN" toward "OUT" marked at the connection point.
When securing the lower flange to the pipeline, press the seat ring against the body until it touches the flange
surface of the pipeline. The lower flange and the pipeline pinch the seat ring and the pipeline’s gasket which is
prepared in advance, and tighten the pipeline bolts rigidly.
If the valve is installed in a horizontal position, be sure to take the support from the yoke or other part of the
actuator.
In case of the extension type bonnet, do not apply insulation to the extended portion.
Provide the required air tubing for the signal pressure and air supply, and the electrical wiring to the
positioner. Make sure no air leaks from the air pipeline.
3. Maintenance
When the control valve needs to be disassembled for inspection, cleaning or polishing the valve seat, follow
the procedures described below.
It explains the following procedure as an example of the attached drawing (MNS-148001).
3.1. Disassembly
Shut off all air supplies, disconnect the tubing for the air supply and the positioner signal pressure, and
the air tubing from the volume tank.
To disassemble the valve, it must be removed from the piping. Bring a chain block over the valve to
remove it from the piping for disassembly and reinstall it after reassembly.
1) Run a strong rope through the actuator yoke and remove the valve retaining bolts from the piping
while slightly pulling the valve upward.
If the valve is installed in a horizontal position, also run a rope around the body so that no lopsided
force is exerted on the valve, when disconnecting the valve from the pipeline.
2) Seat ring (12) and gasket (11) can be taken apart, after the valve body is removed from the pipeline.
At this time, pay attention not to be damaged with the seat ring.
3) Remove the positioner linkage from the split clamp (18) which connects the piston rod (19) of actuator
and the plug (13) of the body side.
4) Loosen the nut (16) or bolt (26) of the split clamp (18) in order to remove the split clamp (18).
Take the record on the depth of insertion of the stem and the position of the split clamp so that they
can be reassembled to the same dimension.
5) Remove the seat ring (12) first from the bottom of the body. The actuator can also be removed by
loosening the drive nut (5) which connects the body (10) and the yoke (14). However, in case of the
stud and nut type connection that connects the yoke to the body by the stud (23) and nut (24), loosen
the nut (24) to remove the actuator from the body.
Remove the packing flange (3) and the packing follower (4), after loosening and removing the stud nut
(2) which have tightened the packing flange. In the case of keeping connecting the valve body and the
yoke, the packing flange can be passed through the space between the bottom end of the piston rod

and the upper end of plug. If the space is narrow, it can be extended by pushing down the plug or
raising the piston rod by hand-wheel operation.
6) Dismantle the plug (13) from the bottom of the body (10).
Note: The disassembly is completed by dismantling the packings (6), packing spacer (8), lantern ring (9)
and guide bushing (7).
7) Inspect for any damages to each component parts.
Note: As the assembly procedure for packing box may vary with the type of valve, please refer to the
respective assembly drawings.
3.2. Polishing the Valve Seat
When the valve seat needs polishing, install the seat ring (12) and plug (13) from the bottom of the
body (10), attaching them tentatively to the body hand-tight, lightly press the plug (13) against the
seat side from the bottom of the body (10), hold the plug with a wrench applied to the wrench holder,
and polish the seating surface. Do not polish the seating surface too hard, otherwise it may be
damaged. When polishing the seating surface, apply a fine-grain, quality abrasive to it. Thoroughly
clean the seating surface prior to reinstallation.
3.3. Reassembly
Reassemble the valve according to the following procedure after having completed the necessary
maintenance.
Please note that new packings and gaskets should be prepared for re-assembly.
1) Clean all the gasket surfaces of the body and the seat ring.
2) Set the guide bushing (7) toward the packing box bottom of the body (10).
3) Insert the plug (13) from the bottom of the body (10). Set the seat ring without the gasket. Stand up
the body.
4) Install the packings (6), packing spacer (8), and lantern ring (9), leaded by the stem of plug (13) and yet
the amount of packings and the order of packings are specified by each valve. When installing the
packings which have the cut ends, they have to be staggered 120 degrees with respect to each
other.
5) Regarding the installation of the packing follower (4) and of packing flange (3), follow the reverse of
the disassembly procedure. Refer to the section 3-1 – point 5.
6) Mount the actuator on the body. At this time, follow the reverse of the disassembly procedure.
Refer to the section 3-1 - point 5.
7) Move down the piston until it stops whether by applying air pressure in the upper part of the actuator
piston or by hand-wheel operation.
8) Couple the piston rod (19) to the plug (13) with the split clamp (18). When coupling, confirm that the
threads of piston rod and plug are completely engaged with each split clamp. It will be useful that
you were marking before disassembling.
Lightly tighten the nut (16) or bolt (26) of split clamp at the position being completely engaged.
9) Raise the plug whether by applying air pressure to the piston bottom of the actuator or by hand-
wheel operation. At that time, the plug is kept away from the seating surface. And then rotate the
plug at a half turn counterclockwise in order to get completely the seating force. You can use the
record made at the time of disassembly to provide the seating clearance.

10) Tighten the nut (16) or bolt (26) of the split clamp.
11) Connect the linkage of positioner to the split clamp (18).
12) Install the body to the pipeline per installation procedures. Do not forget to install gasket between
the seat ring and the body at this time.
13) Reinstall all the air tubing and electric wiring. With the above, re-assembly is completed, but you
must confirm the valve function by checking the valve actuation, valve opening, etc. prior to start-up.
3.4. Packing box
Maintenance of the packing box is a routine work.
The sealing performance of packing is kept by compression of packing. Compression is obtained by
evenly tightening the packing flange stud nut (2) for the packing flange (3), but pay attention to that it
may disturb smooth actuation of valve when tightened too much. New packings are necessary when leak
does not stop even if complete compression made.
