Core Responsibilities

Primary Functions

Execute the complete disassembly of various industrial valves, meticulously documenting and tagging each component for inspection and traceability.
Perform thorough cleaning and detailed visual and dimensional inspections of all valve components to identify wear, corrosion, erosion, or other defects.
Conduct advanced diagnostic procedures, including non-destructive testing (NDT) like dye penetrant or magnetic particle inspection, to assess component integrity.
Skillfully operate specialized machinery such as lathes, milling machines, and surface grinders to repair, remanufacture, or fabricate valve components to precise specifications.
Expertly perform lapping and grinding on critical sealing surfaces of valve seats, discs, and wedges to achieve required flatness and finish for a perfect seal.
Reassemble valves according to manufacturer guidelines, engineering drawings, and established best practices, ensuring correct alignment and torque values.
Conduct rigorous hydrostatic and pneumatic pressure testing on assembled valves to verify shell integrity and seat leakage, ensuring they meet or exceed API, ASME, and client standards.
Accurately set, test, and certify pressure relief valves (PRVs) to specific set pressures, documenting results on test reports and attaching new certification tags.
Read and interpret complex technical documents, including isometric drawings, blueprints, P&IDs (Piping and Instrumentation Diagrams), and repair manuals.
Travel to customer facilities, including offshore platforms, refineries, and power plants, to perform in-line valve maintenance, troubleshooting, and emergency repairs.
Calibrate and function-test valve actuators (pneumatic, hydraulic, electric) and associated instrumentation like positioners and limit switches.
Generate comprehensive and detailed service reports, inspection forms, and test certificates for all work performed, maintaining an accurate record for quality assurance and client review.
Troubleshoot complex valve and actuator operational failures in the field, systematically identifying the root cause and implementing effective, lasting corrective actions.
Ensure all activities are performed in strict adherence to company and client Health, Safety, and Environmental (HSE) policies, including Lockout/Tagout (LOTO) procedures.
Manage and maintain an organized inventory of spare parts, gaskets, packing, and other consumables required for efficient repair operations.
Provide technical guidance and support to clients on proper valve operation, preventative maintenance strategies, and troubleshooting techniques.
Safely rig and operate material handling equipment, such as overhead cranes and forklifts, for the movement of heavy valves and equipment.
Prepare and pack valves and components for shipment, ensuring they are properly protected and documented for transit.
Interface directly with project managers, engineers, and client representatives to provide status updates and technical recommendations.
Participate in and lead pre-job safety meetings (e.g., Job Safety Analysis or JSA) to identify and mitigate potential hazards associated with the work scope.

Secondary Functions

Mentor and provide on-the-job training for apprentices and junior technicians to foster skill development within the team.
Assist the Quality Assurance department with failure analysis and contribute to root cause analysis investigations.
Support workshop and tool management by ensuring equipment is properly maintained, calibrated, and stored.
Contribute to the continuous improvement of work procedures and safety protocols by providing practical feedback and suggestions.
