INSTRUCTION MANUAL
5500 SERIES PLUG VALVES
Operating Instructions
1. Lever: Align lever with valve body to open valve, move lever to 90° of valve body to close.
2. Gear Operator: turn ear operator wheel clockwise to open valve, counterclockwise to close valve.
Maintenance Instructions
Plug valves and installed gear operators on Sleeved plug valves do not require maintenance - periodic lubrica-
tion. However, in the case of any maintenance, follow the below instructions.
1. Always wear protective glove, clothing and eyewear when performing any maintenance operation to avoid
personal injury.
2. Disconnect any operating lines providing air pressure, electric power, etc. Be sure any actuator cannot
suddenly open or close the valve.
3. Use lock-out procedures to be sure that the above measures stay in effect while you work on the
equipment.
4. Check with your process or safety engineer for any additional measures that must be taken to protect
against process media.
5. Certain adjustments may be performed as needed.
Seal Adjustments
1. All J Flow Control Valves are factory adjusted and pressure tested for bubble tight seal. Normally further
adjustment is not required. Should seepage occur at the plug stem or downstream, the following
adjustment procedure should be followed.
Locate the three adjusting bolts spaced at 120° from each other around the plug stem. Each of these bolts
should be tightened in 1/4 turn increments until seepage stops. Care should be taken to prevent over
adjusting as this will result in excessive operating torque. The valve should be operated a full cycle after
each adjustment.
Should seepage still occur after adjustment, seals may require replacement.
Top Seal Replacement
1. Caution: Before attempting to disassemble the valve, care should be taken to flush out any hazardous flu-
ids and release entrapped pressures. Failure to do so could result in serious personal injury.
Top Seal Replacement - Disassembly Procedure
1. Back off the three adjusting bolts until they are several turns clear of contact with the thrust collar.
2. Rotate the plug on
e
or two times which will allow the plug to pop up from the sleeve relieving any pressure
that may be trapped below the plug.
