ARI-STEVI 12.440 Pneumatic Proportional Control Valve with Positioner DN80 PN16
Achieve millimetre-precise flow modulation in high-capacity process lines.
ARI-STEVI 12.440 Pneumatic Proportional Control Valve is ideal for modulating fluid flow and pressure in the high-capacity lines of industrial facilities. In addition, the STEVI-POS electropneumatic positioner provides flawless control through 4-20 mA signals with non-contact magnetic sensing technology. Moreover, a Kvs capacity of up to 100 m³/h makes this valve indispensable in critical processes.
The AISI 420 stainless steel trim and 300 °C temperature resistance deliver high operational efficiency under the toughest conditions. The DN80 nominal diameter and PN16 pressure class, therefore, allow safe use in large-diameter pipelines. Furthermore, this model’s Kvs value ranges from 63 to 100 m³/h, meeting precise proportional control needs in high-flow systems. The STEVI-POS unit includes an integrated LCD screen for easy on-site monitoring and configuration.
