Control and Valve Installers and Repairers, Except Mechanical Door
Tasks
Core Tasks Include:
- Disassemble and repair mechanical control devices or valves, such as regulators, thermostats, or hydrants, using power tools, hand tools, and cutting torches.
- Record maintenance information, including test results, material usage, and repairs made.
- Lubricate wearing surfaces of mechanical parts, using oils or other lubricants.
Supplemental Tasks Include:
- Turn meters on or off to establish or close service.
- Turn valves to allow measured amounts of air or gas to pass through meters at specified flow rates.
- Report hazardous field situations and damaged or missing meters.
- Record meter readings and installation data on meter cards, work orders, or field service orders, or enter data into hand-held computers.
- Connect regulators to test stands, and turn screw adjustments until gauges indicate that inlet and outlet pressures meet specifications.
- Disconnect or remove defective or unauthorized meters, using hand tools.
- Test valves and regulators for leaks and accurate temperature and pressure settings, using precision testing equipment.
- Install regulators and related equipment such as gas meters, odorization units, and gas pressure telemetering equipment.
- Shut off service and notify repair crews when major repairs are required, such as the replacement of underground pipes or wiring.
- Examine valves or mechanical control device parts for defects, dents, or loose attachments, and mark malfunctioning areas of defective units.
- Attach air hoses to meter inlets, plug outlets, and observe gauges for pressure losses to test internal seams for leaks.
- Dismantle meters, and replace or adjust defective parts such as cases, shafts, gears, disks, and recording mechanisms, using soldering irons and hand tools.
- Advise customers on proper installation of valves or regulators and related equipment.
- Connect hoses from provers to meter inlets and outlets, and raise prover bells until prover gauges register zero.
- Make adjustments to meter components, such as setscrews or timing mechanisms, so that they conform to specifications.
- Replace defective parts, such as bellows, range springs, and toggle switches, and reassemble units according to blueprints, using cam presses and hand tools.
- Investigate instances of illegal tapping into service lines.
- Install, inspect and test electric meters, relays, and power sources to detect causes of malfunctions and inaccuracies, using hand tools and testing equipment.
- Trace and tag meters or house lines.
- Mount and install meters and other electric equipment such as time clocks, transformers, and circuit breakers, using electricians' hand tools.
- Vary air pressure flowing into regulators and turn handles to assess functioning of valves and pistons.
- Measure tolerances of assembled and salvageable parts for conformance to standards or specifications, using gauges, micrometers, and calipers.
- Repair leaks in valve seats or bellows of automotive heater thermostats, using soft solder, flux, and acetylene torches.
- Clean internal compartments and moving parts, using rags and cleaning compounds.
- Repair electric meters and components, such as transformers and relays, and replace metering devices, dial glasses, and faulty or incorrect wiring, using hand tools.
- Cut seats to receive new orifices, tap inspection ports, and perform other repairs to salvage usable materials, using hand tools and machine tools.
- Splice and connect cables from meters or current transformers to pull boxes or switchboards, using hand tools.
- Clean plant growth, scale, paint, soil, or rust from meter housings, using wire brushes, scrapers, buffers, sandblasters, or cleaning compounds.
- Calibrate instrumentation, such as meters, gauges, and regulators, for pressure, temperature, flow, and level.
