The SA/CL is an analog positioner available in a pneumatic and electro-pneumatic version. The positioner has a heavy duty design making it suitable for use in very harsh conditions. It is used as the control part of the pneumatic valve set in oil and gas, refining, chemical, power, metal production and other fields with automated systems. The UP-2 pneumatic version accepts a 3-15 psi (0.2-1 bar) signal and the electro-pneumatic version a 4-20 mA signal.

• When using the electro-pneumatic version an I/P converter is installed on the pneumatic positioner which allows an electric signal to pilot the positioner. It is based on the balanced-forces principle; air distribution to actuator chambers is executed by an internal spool.
• The SA/CL is designed to be used for applications on linear actuators with a stroke length of up to 70mm. This positioner is double acting but can also be used as single acting if required.
• Metallic case.
• Heavy duty design.
• High reliability.
• Integrated bypass only for ND 1/4” version.
• Action inversion without tubing inversion only for ND 1/4” version.
• Air purge version.
• Sandstorm execution.
• Split range signal.
• Special characterisation/range.
• Suitable for big size/fast stroking actuator.
