10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance.Valves may include high and low pressure and temperature valves that are flanged and bolted; dampers and hydro regulating valves; gate; globe; wafer; uni-flow; plug; ball; knife; rotary; piston (ported); diaphragm; non-return; pinch; pressure relief; regulating; isolating; slide dampers; isolating and regulating blade dampers; gas regulating or isolating dampers; hydro turbine guide vanes; and shutters.Precision measuring devices may include inside/outside micrometers, verniers, engineer’s rule, dial gauges, depth gauges and feeler gauges.Testing may include pressure testing (hydraulic and vacuum), blue check.Valve may control solutions which may include gases; solids; and fluids and chemicals such as caustic soda, chlorine, ammonia, sulphuric acid, sodium hypochlorite, hydrazine, diethylamine, citric acid, hydrofluoric acid, ammonium molydate, trisodium phosphate, hydrogen, nitrogen, carbon dioxide, water, fly-ash, slurry, compressed air, brine, oil, steam (superheated and saturated), hydrogen, propane and carbon dioxide.Valve drives may include electrical, mechanical, pneumatic, hydraulic or manual.Work completion details may include plant and maintenance records, job cards, check sheets, on device labelling updates and reporting and/or documenting equipment defectsWork site environment may be affected by nearby plant or processes, e.g. chemical, heat, dust, noise, gas and oil.Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1.00 Preliminary Information and Glossaries. |
