Control and Valve Installers and Repairers, Except Mechanical Door — Tasks

Task statements

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