Samson 3730 Pneumatic Valve Positioner for Automation Process Industry Pipeline Regulation

The Samson 3730 is a high-performance intelligent pneumatic valve positioner professionally developed for full-process automation pipeline regulation in petrochemical, energy, pharmaceutical, water treatment and other process industries. Designed to match linear and rotary pneumatic actuators, this electro-pneumatic integrated positioner converts control system electrical input signals into precise pneumatic output pressure, realizing closed-loop accurate positioning of process control valves.

Adopting Samson original modular pneumatic control structure and adaptive calibration algorithm, it delivers stable valve stroke control, strong environmental adaptability and low maintenance cost. It supports on-site automatic parameter setting and remote digital communication, perfectly adapting to continuous, high-precision pipeline medium flow, pressure, liquid level and temperature regulation scenarios under complex industrial working conditions.
