Valve Positioner - Electric-pneumatic Control System | Precision Signal Conversion, High-speed Valve Adjustment, Feedback Mechanism For Enhanced Performance

We are engaged in manufacturing, exporting, distributing and supplying excellent quality Valve Positioner in Shanghai, Shanghai, China. Positioner is auxiliary instruments used with pneumatic adjusting valve, receive DC signal from electric regulating instruments and convert the signal to corresponding pneumatic signal, control adjusting travel. By the action of feedback system , make the travel and signal change proportionally, then ensure the correct position of valve. If used with positioner, can overcome the friction of valve stem, speed up the movement of valve. Widely used in oila chemicala metallurgya power station and textile automation system of industries
