ARI-STEVI 12.440 Pneumatic Proportional Control Valve with Positioner DN32 PN16
Precision flow modulation for demanding industrial processes, even at 300 °C.
ARI-STEVI 12.440 Pneumatic Proportional Control Valve manages flow, pressure and temperature parameters with millimetric precision in industrial facilities. In addition, its DN32 nominal diameter and PN16 pressure class deliver excellent modulation capability in steam and hot water lines. Furthermore, the ARI-DP 32 actuator converts incoming signals into graduated flow adjustment, therefore maximising system efficiency. Moreover, it withstands 40 bar differential pressure, offering an unmatched solution in its segment.
The AISI 420 stainless steel trim provides outstanding resistance to corrosion and wear. As a result, the valve operates stably even at working temperatures up to 300 °C. The STEVI-POS digital positioner uses a magnetic Hall sensor for contactless detection, consequently eliminating mechanical wear. The body is made of EN-JL1040 cast iron, the bonnet of EN-JS1049 ductile iron, and sealing uses a PTFE V-ring rated to a maximum of 220 °C.
