SAMSON POSITIONERS About
SAMSON (Germany) is a major manufacturer of control-valves, actuators, and associated automation components.
What is a valve positioner & its role
-
A positioner is a device that ensures the valves physical position (opening / closing) matches the control signal from the controller.
-
It compares the input control signal (pneumatic or electrical) to the actual valve position (feedback) and adjusts the valve actuators pressure to correct any error.
-
In many cases, the positioner also acts as a servo booster, converting a low-energy input signal into a higher pressure output (e.g. up to the supply pressure, e.g. 6 bar / 90 psi) to drive the actuator.
Precision in Pneumatic ControlEngineered for dependable actuator positioning, the SAMSON Model 3725 excels in applications requiring precise transition from electrical to pneumatic signals. Its advanced firmware ensures stable operation, even under fluctuating supply conditions. Users benefit from consistent and repeatable positioning, ensuring optimal process control.
Comprehensive Compliance and UsabilityThe device is certified with CE and EAC approvals, ensuring it meets international standards for safety and performance. Its intuitive electronic control system and user-friendly QR code make installation, configuration, and maintenance efficient, supporting seamless integration into diverse control systems.
