SA/CL- Analog Valve Positioner
Heavy-duty analogue positioner for precise valve control in demanding industrial environments.
Precise valve positioning with stable air distribution.
Rugged design for extreme environments.
Compatible with single and double-acting actuators.
Features
The SA/CL is a robust analogue positioner available in pneumatic and electro-pneumatic versions. Designed for automated systems in oil and gas, refining, chemical, power, and metal industries, it operates using a 3-15 psi pneumatic signal or a 4-20 mA electro-pneumatic signal. The positioner utilises a balanced-forces principle for precise air distribution to actuator chambers. Suitable for linear actuators up to 70mm stroke, it is available in single or double-acting configurations. Featuring a metallic housing, IP65 protection, and options for explosion-proof and intrinsically safe versions, the SA/CL ensures reliable operation in harsh environments, including sandstorm and corrosive conditions.
