ARI-STEVI 12.440 Pneumatic Proportional Control Valve DN40 PN16
Precise flow and pressure control for stable industrial processes.
The ARI-STEVI 12.440 Pneumatic Proportional Control Valve manages flow and pressure parameters with millimetric precision in industrial processes. In addition, its ARI-DP 32 pneumatic actuator provides modulated control within a 0.8-2.4 bar signal range. Furthermore, it delivers high performance especially in steam and hot water lines.
The EN-JL1040 cast iron body provides a robust foundation, while the EN-JS1049 ductile iron bonnet adds structural strength. Moreover, the AISI 420 stainless steel stem, disc and seat offer outstanding corrosion resistance. Therefore, the PTFE V-ring sealing element ensures safe operation up to 220 °C, and the maximum working temperature reaches 300 °C.
