Valve Maintenance & Repair
Class ID: TR-9-70200-HA
Description
Course provides instruction on manual gate, globe, check, and butter y valve maintenance and troubleshooting. The classroom discussion and hands-on experience covers the principals of operation and proper inspection, adjustment, and reassembly of the valves. Valve packing principals, proper removal, installation and inspection is are presented. Valve seat and wedge blue checking techniques are also discussed.
- Standard Class Size: 6 Students per Instructor
- Maximum Class Size: 8 Students per Instructor
- Course Duration: 5 days
- Supplied Materials: Electronic training manual for each student
- Suggested Attendees: Plant mechanics/machinists/pipefitters, mechanical foremen, QC personnel, engineering personnel, ISI personnel, MOV test group personnel, and operations personnel.
- Course Description:Course provides instruction on how to maintain gate, globe, check, and butterfly valves to optimum working condition. The classroom discussion and hands-on experience covers the principals of operation, disassembly, inspection, adjustment, and reassembly of the valves. An overview is presented on the techniques of packing removal and installation, lapping of valve seats and wedges to facilitate fit up, blue check, and in-line machining of valve components including the use of specialty tools.
Each student will be required to pass a written test with a minimum score of 80% in order to successfully complete this course. Upon successful completion of this training course, the student will:
- Identify and explain the design and use of gate valves, globe valves and check valves.
- Perform disassembly, repair, adjustments, and reassembly of gate valves, globe valves and check valves.
- Perform required preventative maintenance and repair on gate valves, globe valves and check valves.
After completing this course, the student will:
- Take exact measurements of critical valve components using calipers, micrometers and torque wrenches.
- Identify valve markings and explain valve name plates, component identifications, valve match markings, inspection reports, and bridge wall markings.
- Perform the basic procedure for installing soft, hard, and pressure sealed gaskets.
- Perform blue checking a valve disc and seat and explain the results.
- Perform and discuss the basic procedures for lapping a valve seat.
- Perform and discuss unpacking and repacking a valve.
- Discuss the principles of operation and the applications and limitations of gate, globe, check, and pressure seal valves.
- Perform and discuss the disassembly, inspection, repair, adjustment and reassembly of gate, globe, check, and pressure seal valves.
- Explain the functions of valve machining equipment.
- Increased knowledge of valve design, construction, and function which in turn will improve workmanship, efficiency, and enhance the troubleshooting efforts.
- Improved maintenance practices which results in fewer maintenance related valve actuator failures, improved valve reliability and increased valve life.
- Decrease the number of errors made in valve disassembly/reassembly.
