ARI-STEVI 12.405 Pneumatic On-Off Control Valve Dn80 PN16

ARI-STEVI 12.405 Pneumatic On-Off Control Valve DN80 PN16 High Temperature and Pressure Resistant Automatic Flow Control

The ARI-STEVI model 12.405 pneumatic on-off control valve is a reliable solution for automatic on-off control in industrial fluid systems. Its DN80 connection diameter and PN16 pressure class make it ideal for medium to large-scale installations.

Equipped with an EN-JL1040 cast iron body and AISI 420 stainless steel internal components, the valve can operate safely at temperatures up to 300°C. The PTFE-V sealing ring provides maximum resistance up to 220°C. A DIN EN 12266 Class A leakage rate ensures 100% leakage. Compatible with ARI-DP series pneumatic actuators, this model can be selected as normally open or normally closed. Its high performance, long life, and low maintenance requirements increase plant safety and energy efficiency.
