Always recommended to use air filter regulator (i.e. YT-200 series).
Young Tech Co., Ltd
has not tested positioner’s operation with any other gases
other than clean air. Please contact Young Tech Co., Ltd for any questions.
4.2
Supply Pressure Condition
Dry air with at least 10
℃
lower than ambient temperature.
Avoid from dusty air. Positioner’s inner filter can only filter 5 micron or larger.
Avoid
oil.
Comply with ANSI/ISA-57.3 1975(R1981) or ISA S7.3-1975(R1981).
Supply pressure range is 1.4 ~ 7 kgf/cm
2
(140-700 kPA)
Set air filter regulator’s pressure level 10% higher than actuator’s spring range pressure.
4.3 Piping
Condition
Ensure inside of pipe is clean of obstructions.
Do not use pipeline that is squeezed or shows any type of damamges.
