4 Installation
4.1 Install the valve and topworks
NOTICE:
The topworks size and configuration can limit the actual operating pressure. Consult the Pure-
Flo catalog for pressure limitations. Consult the factory or engineering catalog for vacuum op-
eration.
1. If you have a weld end valve, then consider the following:
If you are welding ... Then ...
Manually Remove the topworks.
In line for schedule 5 or
lighter pipe and tubing
You can weld with automatic equipment. Before you perform the weld:
1. Remove the topworks (optional).
2. If left installed, set the valve to the open position.
3. Properly purge the valve with an inert gas.
2. Install the valve.
3. Prior to pressurization (with the valve slightly open), tighten the bonnet fasteners.
For more information, see 4.2 Tighten the bonnet fasteners on page 7.
4. Cycle the valve two to three times to verify smooth operation.
4.2 Tighten the bonnet fasteners
CAUTION:
Do not tighten fasteners while the system is pressurized or at elevated temperatures (greater
than 38°C | 100°F).
1. Depressurize the system.
2. Tighten the bonnet fasteners in a crisscross pattern.
For more information, see 4.2.1 Fastener torque table for valve body to topworks on page 8.
3. Make multiple crisscross passes to build up torque to the final table value. Make additional criss-
cross passes using final table values to evenly tighten each fastener to within 5% of torque value.
4. Retighten the bonnet fasteners as noted above at ambient conditions after the system has cycled
through operating pressure and temperature.
5. Monitor the valve for leakage:
If leakage ... Then ...
Occurs at the body/bonnet
flange sealing area
Depressurize the system and retighten the bonnet fasteners as noted
above.
Continues Depressurize the system and retighten the bonnet fasteners as noted
above. (maximum 3rd re-torque)
Continues Replace the valve diaphragm.
For more information, see 6.5 Replace the valve diaphragm on page 12.

6 Maintenance
6.1 Precautions
WARNING:
•All procedures must be performed by qualified personnel.
• When the process fluid is hazardous, thermal (hot or cold), or corrosive, take extra pre-
cautions. Employ the appropriate safety devices and be prepared to control a process
media leak.
• Always wear protective clothing and equipment to safeguard the eyes, face, hands, skin,
and lungs from the fluid in the line.
6.2 Inspection
Inspection area What to look for Action if problem is found
External valve parts Excessive wear or corrosion • Replace the affected parts
•Contact ITT to obtain replace-
ment parts or for specific in-
structions
Non sealed bonnet Replace the valve diaphragm
Topworks Spindle binding, excessive noise, or
dried lubricant
Diaphragm and valve body Leakage between the diaphragm and
valve body
Tighten the bonnet fasteners
For more information, see:
•6.5 Replace the valve diaphragm on page 12
•4.2 Tighten the bonnet fasteners on page 7
6.3 Lubrication requirements
Lubrication schedule
Remove residual grease prior to re-lubrication. Lubricate the spindle threads, lower spindle face and
neck where it interfaces with the compressor, and o-ring whenever the topworks is disassembled. Bon-
nets are not equipped with grease fittings and must be disassembled to be lubricated.
Acceptable lubricants
Brand Lubricant type
Chevron DOW 111 for o-ring

6 Maintenance
Handwheel Operated Valves (970) Installation, Operation, and Maintenance Manual 11

b) Rotate the handwheel to lower the compressor diaphragm assembly.
6.5 Replace the valve diaphragm
1. Disassemble the valve.
For more information, see 6.4 Disassemble the valve on page 11.
2. Unscrew the diaphragm from the compressor by turning the diaphragm counterclockwise.
The replacement diaphragm should be identical in size and grade to the original diaphragm.
3. Rotate the diaphragm until hard stop or heavy resistance is achieved and additional force does not
significantly rotate the diaphragm into the compressor.
4. If replacing a PTFE diaphragm, re-invert the diaphragm.
5.
For more information, see 4.2 Tighten the bonnet fasteners on page 7.
6.6 Change the diaphragm type

If you are changing ... Then ...
From an elastomer to a PTFE diaphragm Install a tube nut into the hexagonal hole in the new com-
pressor
From a PTFE to an elastomer diaphragm Change to the new compressor.
5. Lubricate the spindle end where it interfaces with the compressor.
6. Locate the new compressor on the spindle and turn the handwheel counter clockwise to raise the
assembly into the bonnet.
7. Replace the diaphragm.
For more information, see 6.5 Replace the valve diaphragm on page 12.
6.7 Replace the o-ring
