INSTRUCTION MANUAL
5500 SERIES PLUG VALVES
Scope of Manual
This instruction manual includes installation, maintenance and parts information for the J Flow 5500 Series
Plug Valve.
Do not install, operate or maintain a 5500 Series valve without being fully trained and qualified in valve in-
stallation, operation and maintenance. To avoid personal injury or property damage, it is important to carefully
read, understand and follow all the contents of this manual including all safety cautions and warning. If you
have any questions about these instructions, contact J Flow Controls before proceeding.
Installation Instructions
1. Before installing, inspect the valve and any associated equipment for damage and any foreign material.
Make certain the valve interior is clean and the pipelines are free of foreign material.
2. Use accepted piping and welding practices when installing the valve in the line.
FLANGED PLUG VALVES
1. Remove flange protectors
2. Insert valve into process line
3. Use appropriate gasket and bolts, and bolt the valve into your process line
SOCKET WELD AND BUTT WELD VALVES
1. Socket weld and butt weld plug valves must be welded into line prior to operation. Use only ASME qualified
procedures and personnel for weld instruction.
2. Remove the plastic protection cap.
3. Inspect the valve and any associated equipment for damage and any foreign material. Make certain the
valve interior is clean and the pipelines are free of foreign material.
4. The area to be welded should be cleaned of grease and oil and moisture free.
5. The valve should be shipped in the open position.
6. Carefully examine the maximum temperatures of the body sleeve area. You should not exceed the respec-
tive maximum temperatures. Contact the factory for additional help if needed.
7. Th welder can wrap a damp, fireproof cloth around the body at core area to reduce the temperature at the
body sleeve area. Cold water can also be poured as needed to reduce the temperature.
8. For valves with socket welding end - insert the tube in the socket to maximum and retract is 0.08”. Make
two welding tacks to define welding position then continue welding.
9. For valves with butt weld ends, leave a 0.08” gap between pipe and valve end and fill gap with weld for full
penetration.
10. Weld using low heat input and gradual welding technique. Discontinue welding after each pass or as often
as needed. When ordered, the valve configuration and construction materials were selected to meet partic-
ular pressure, temperature, and controlled fluid conditions. Some body/trim material combinations are limit-
ed in their pressure drop and temperature ranges. Do need exceed maximum temperatures of materials.
Allow the metal to cool below 175 degrees F prior to continuing the weld.
