The Senior Control Valve Technician is responsible for independently performing complex servicing, troubleshooting, calibration, and overhauling of control and isolation valves, with specialization in dosing systems. The role includes leading field teams, mentoring junior staff, and ensuring compliance with technical standards, safety procedures, and plant reliability goals.
Lead valve maintenance and overhauling tasks including dismantling, inspection, repair, and reassembly of various control and isolation valves (e.g., diaphragm, butterfly, globe, ball, and gate valves).
Calibrate and configure valve positioners (electropneumatic/digital), actuators (pneumatic/electric/hydraulic), and control accessories.
Perform advanced diagnostics and testing including seat leakage, stroke verification, actuator pressure tests, and shut-off checks.
Review and interpret technical documents such as P&IDs, valve datasheets, control loop drawings, and OEM manuals.
Support critical maintenance during plant shutdowns and commissioning—including loop checks and system readiness for dosing systems.
Ensure completion and accuracy of all maintenance records, test sheets, and valve history logs in CMMS.
Provide technical input on valve selection, upgrades, and retrofits.
Train and mentor junior and mid-level technicians in proper handling, servicing, and troubleshooting techniques.
