ARI-STEVI 12.440 Pneumatic Proportional Control Valve with Positioner DN20 PN16

ARI-STEVI 12.440 Pneumatic Proportional Control Valve with Positioner DN20 PN16

Precise, wear-free modulation for demanding steam and hot water processes.

ARI-STEVI 12.440 Pneumatic Proportional Control Valve delivers millimetre-precise flow control in steam and hot water systems. Furthermore, its 40 bar maximum differential pressure rating ensures stable performance in the most demanding industrial processes. In addition, the STEVI-POS positioner integration brings wear-free magnetic sensing technology for long service life and high linearity.

The EN-JL1040 cast iron body and AISI 420 stainless steel internals resist corrosion effectively. Moreover, the PTFE V-ring seal allows safe operation up to 220°C, while the valve body withstands temperatures up to 300°C. A 4-20 mA signal input enables straightforward integration into central automation systems. therefore, the valve maintains class D leakage as per DIN EN 12266.
