Introduction
The following instructions are designed to assist maintenance
personnel in performing most of the maintenance required on
the 37002 Series valve. Baker Hughes has highly skilled service
people around the world available for startup, maintenance and
repair of our valves and component parts. In addition, a regularly
scheduled training program is conducted to train customer service
and instrumentation personnel in the operation, maintenance and
application of our control valves and instruments. Arrangements
for these services can be made through your local Baker Hughes
Representative. When performing maintenance use only Baker
Hughes replacement parts. Parts are obtainable through your
local Masoneilan Representative. When ordering parts always
include Model and Serial Number of the unit being repaired.
These installation and maintenance instructions apply to all
sizes and ratings of the Masoneilan 37002 Series control valves,
regardless of the type of trim used. The model number, size and
rating of the valve are shown on the identification tags located
on the actuator. Refer to Figure 1 to identify valve nomenclature.
Unpacking
Care must be exercised when unpacking the valve to prevent
damage to the accessories and component parts. Should any
problems arise contact your Baker Hughes Representative or
Sales Office.
Installation
1. The valve is flangeless and has a rating of 300 lb ANSI. It
may be installed between machined flanges of the following
ANSI standards; 125 lb., 150 lb., 250 lb.. and 300 lb. ANSI
flanges as well as DIN (ND) 10, 16, 25 and 40 metric flanges.
2. Before installing the valve in the line, clean piping and
valve of all foreign materials, such as welding chips, scale,
oil, grease or dirt. Gasket surfaces should be thoroughly
cleaned to ensure leak proof joints.
3. To allow for inline inspection, maintenance and removal of
the valve without service interruption, provide a manually
operated stop valve on each side of the valve with a manually
operated throttling valve mounted in the bypass line.
4. The valve may be installed in the line so that the control
substance will flow in either direction. However, the actuator
must be located in one of the recommended positions
shown in Figure 1.
CAUTION

Prior to installing the valve in the line, this section
should be completely reviewed and understood.

Installation - Assembly
5. Where insulation of the valve body is required, do not
insulate the valve bonnet. Figure 2 shows a recommended
method tor insulation.
Figure 2
6. Special bosses are provided on the valve body to center
the valve in the line and prevent rotation prior to tightening
the flange bolts. Before placing the valve in the line, install
the lower flange bolting to provide a kind of cradle, this will
support the valve while installing the remaining bolts.
CAUTION
CAUTION
WARNING
DANGER
Due to the different actuator to body congurations,
the center of gravity for lifting the valve will change. It
is recommended that the valve be test lifted to ensure
it will not shift suddenly, possibly causing injury or
damage.
7. Where possible, use welding neck or flat face flanges with
a full line bore. When the valve has an elastomer liner, the
l.D. of the mating flanges must match the l.D. of the liner and
cover the entire face of the liner.
Note: Refer to Installation Alignment section for the
recommendations on valve alignment as well as
installation in standard commercial wrought steel pipe,
and tubing, and heavy wall pipe.
CAUTION
CAUTION
WARNING
DANGER
When the valve is installed in lines constructed with
standard commercial wrought steel pipe or heavy wall
pipe, slip-on or screwed anges are not recommend-
ed with lined valves.
8. Regardless of valve action (air to close or air to open) the
valve should be installed in the line with the vane in the
closed position. The following are recommended means for
closing the vane for valve installation:
A. If the valve is equipped with a handwheel, close the valve
using the handwheel.
Note: For lined valves, the closed position is achieved
when the vane makes full contact with the liner.
B. If the valve is not equipped with a handwheel, a portable
regulated air supply may be used lo supply pressure to the
actuator and close the vane.
Note: On lined valves only enough air pressure should
be supplied to ensure that the vane makes full contact
with the liner.
C. The following method is highly recommended and should
be used whenever possible. Rotate the hand wheel to the
disengaged position. Refer to Figure 19 and remove side
covers (56). remove retaining rings (11) and push out pivot
pin (12). The actuator is now disengaged from the valve
shaft and allows for manu ally closing the valve by rotating
lever (33) in proper direction.
Note: If the valve s equipped with a handwheel, remove
spacers (10) and rotate the handwheel so that the lever
arm (37) will not interfere with manual movement of
the lever (33). On lined valves rotate the vane until full
contact is made with the liner.
CAUTION
CAUTION
WARNING
DANGER
Ensure that the valve is operating in the quadrant
shown in Figure 11.
9. Center the valve in the pipe line (install gaskets if an unlined
valve) and tighten bolting evenly and in criss-cross fashion.
Note: Gaskets are not used for lined valves. The elas-
tomer liner is flangeless and acts as its own controlled
compression gasket, therefore it should be tightened
until the flanges meet evenly with the valve body.
10. At this time the vane should be rotated manually a few times
to ensure that it clears adjacent internal piping and flanges.
It is not recommended that the vane be stroked, either using
handwheel or actuator; it should be stroked manually so that,
should interference occur, this will be readily determined
and will prevent damage to the vane.
11. If Step C, previously mentioned, was used, refer to
Reassembly of Actuator to Bracket Section, to reassemble
pivot pin (12), retaining ring (11) and spacer (10).

Installation - Alignment
Alignment Warning
This valve must be properly aligned with the piping to prevent
pipe interference with the disc. After installing the valve, check
disc rotation as follows:
1. Disconnect actuator from disc. To do this, refer to point
8.C. of Installation - Assembly Section to remove clevis pin
from the split clamp arm. Rotate clamp arm to free pin if
necessary.
2. Rotate clamp arm slowly to prevent damage to the disc
sealing edge if interference occurs. If disc can rotate through
90°arc, alignment is correct.
3. Realign valve with pipe if there is interference.
4. Reassemble.
If heavy wall piping or thin wall piping or tubing is used, see other
instructions from this Installation - Alignment section.
Standard Commercial Wrought Steel
Pipe
Use only flat face or raised face flanges. If using iron flanges, limit
bolting torque to prevent fracture of the flange which is not fully
supported by the MiniTork body. Use only carbon steel (ASTM
A307 GrB or equivalent) bolting with iron flanges.
Weld Neck Flanges
Flange bore should be Schedule 40.
Gaskets are required for unlined valves only.
Gasket Inside Diameter (I.D.) should be equal to pipe Outside
Diameter (O.D.).
