What are the responsibilities and job description for the Control Valve Technician position at Century Instrument & Machine Co., Inc.?
Job Overview
We are seeking a highly skilled and motivated Control Valve Technician for a short-term international mobilization to Central Africa for between 20 – 37 days. Technicians will work alongside existing personnel in a local company in Central Africa performing actuator overhaul across the facility's control valve population which are about 92 work items spanning process units 1011 through 1016, including positioner replacement (including Fastrak positioners), soft goods replacement, solenoid valve assembly replacement, and actuator diaphragm replacement. In this role, you will be responsible for maintaining, troubleshooting, and repairing control valves and associated instrumentation within industrial manufacturing environments. Your expertise will ensure optimal system performance, safety, and reliability across various automated processes.
Duties
- Disassemble actuator components: springs, diaphragms, pistons, seals, positioners, limit switches, I/P converters, linkages, yokes, and stem connectors; per OEM guidelines, tagging and segregating reusable and replaced parts.
- Replace worn or damaged seals, diaphragms, springs, bearings, gaskets, and O-rings, and install new overhaul kits.
- Reassemble actuators to OEM tolerances and torque specifications, ensuring correct alignment of linkages and positioner mounting.
- Restore electrical and pneumatic connections and apply lubrication per OEM specifications.
- Perform calibration: zero and span adjustment, travel stroke calibration, air supply pressure verification, and positioner tuning/response testing.
- Conduct leak tests (air/hydraulic), travel time and repeatability checks, and fail-safe function tests (fail-open/fail-closed).
- Confirm each actuator's performance meets OEM and operational requirements before sign-off.
- Complete site HES induction, follow permit-to-work procedures, and participate in daily toolbox talks.
- Maintain accurate, legible calibration and test records for client review.
- Perform installation, calibration, and maintenance of control valves, sensors, and pneumatic systems in accordance with engineering specifications and schematics.
- Troubleshoot complex control valve issues using electrical diagnostics tools such as ohmmeters, multimeters, and advanced calibration equipment.
- Read and interpret piping and instrumentation diagrams (P&IDs), schematics, electrical blueprints, and system drawings to accurately diagnose problems.
- Conduct preventive maintenance on hydraulic, pneumatic, and electrical components to minimize downtime and maximize system efficiency.
- Program, configure, and troubleshoot programmable logic controllers (PLCs) and distributed control systems (DCS) to support automation processes.
- Utilize precision measuring instruments for calibration and alignment of control valves and sensors to ensure precise operation.
- Collaborate with engineering teams on troubleshooting engineering issues related to industrial automation, high voltage systems, or low voltage controls.
Skills
- Minimum 5 years' hands-on experience in control valve and actuator overhaul, calibration, and testing.
- Demonstrated experience with relevant OEM control valve and positioner platforms, including Fastrak positioners.
- Working knowledge of pneumatic/electro-pneumatic actuator systems, positioner tuning, and fail-safe testing.
- Relevant instrumentation/control valve certifications preferred.
- Valid, unrestricted passport with at least 12 months' validity from the assignment start date.
- Ability to pass a pre-mobilization medical exam, including yellow fever vaccination, other required vaccinations and a background/drug screening.
- Fluent spoken and written English.
- Willingness and ability to work 7 days/week, 12 hours/day for the full assignment duration (approx. 5 weeks and 2 days), in a remote international location.
- Copies of relevant certifications and a valid passport photo page must be provided if shortlisted for an interview.
- Extensive knowledge of hydraulics, pneumatic systems, and mechanical components related to control valves.
- Strong electrical experience including electrical diagnostics, blueprint reading, safety procedures, and troubleshooting in industrial environments.
- Proficiency with engineering troubleshooting techniques using sensors, vision inspection systems, Calypso software, AutoCAD drawings, and schematics.
- Experience with industrial maintenance practices across manufacturing settings with a focus on safety standards.
- Familiarity with programming in engineering contexts such as PLCs or similar automation platforms.
- Ability to read P&IDs and schematics accurately; experience with calibration procedures is essential.
- Knowledge of high voltage and low voltage electrical systems; experience working with distributed control systems (DCS) or CNC machinery is a plus.
- Strong customer service orientation with excellent communication skills for field service interactions.
