5.1
Safety
➢ Supply pressure should be clean and dry air – avoiding moisture, oil and dust.
➢ Always recommended to use air filter regulator (i.e. YT-200 series).
➢ Rotork YTC Limited has not tested positioner’s operation with any other gases other than
clean air. Please contact Rotork YTC Limited for any questions.
5.2
Supply Pressure Condition
➢ Dry air with dew point of at least 10 °C lower than ambient temperature.
➢ Avoid from dusty air. Use 5 micron or smaller filter.
➢
Avoid oil.
➢
Comply with ISO 8573-1 or ISA 7.0.01.
➢ Supply pressure range is 0.14 ~ 0.7 MPa (1.4 ~ 7 bar)
➢ Set air filter regulator’s pressure level 10 % higher than actuator’s spring range pressure.
5.3
Piping Condition
➢ Ensure inside of pipe is clean of obstructions.
➢ Do not use pipeline that is squeezed or shows any type of damamges.
➢ Pipeline should have more than 6 mm of inner diameter (10 mm outer diameter) to maintain flow
rate.
➢ The length of pipeline system should not be extremely long. Longer pipeline system may affect
flow rate due to the friction inside of the pipeline.
