ARI-STEVI 12.440 Pneumatic Proportional Control Valve with Positioner PN16 DN50

ARI-STEVI 12.440 Pneumatic Proportional Control Valve with Positioner (DN50)

PN16 | Intelligent Positioner Control | German Engineering Technology

The ARI-STEVI 12.440 DN50 pneumatic proportional control valve is a professional automation solution designed to manage fluid flow rate, pressure, or temperature with high precision in industrial process lines. Thanks to the integrated intelligent positioner unit, this pneumatic proportional control valve converts the 4-20mA signal from the controller into a millimeter stroke movement, maximizing system stability. The durable cast iron body with PN16 pressure rating makes this pneumatic proportional control valve model an ideal choice for steam, superheated water, and gas lines. The positioner feedback feature instantly compensates for deviations caused by differential pressure changes, offering millimeter adjustment precision on this pneumatic proportional control valve unit. As a professional pneumatic proportional control valve, the STEVI 440 provides linear or equal percentage flow characteristics thanks to its parabolic plug made of stainless steel. This pneumatic proportional control valve in DN50 size is equipped with maintenance-free self-adjusting sealing packages, promising long operational life. Manufactured with German ARI-Armaturen quality, this pneumatic proportional control valve is an intelligent investment that increases process safety while minimizing energy costs. Choosing a high-quality pneumatic proportional control valve is the most critical automation component that reduces downtime and standardizes product quality in your production line.
