ARI-STEVI 12.405 Pneumatic On-Off Control Valve PN16 DN80

Automates flow with reliable tight shut-off in demanding industrial lines.

ARI-STEVI 12.405 Pneumatic On-Off Control Valve automates fluid management in industrial plants. In addition, it operates safely with DN80 diameter and PN16 pressure rating in steam, hot oil, and high-temperature lines. Moreover, the ARI-DP diaphragm actuator converts the air signal into immediate physical movement. Furthermore, the EN-JL1040 cast iron body provides stable structure up to 300°C.

The PTFE V-ring stem seal requires no maintenance and ensures 100% sealing with DIN EN 12266 Class A leakage rate. Additionally, the AISI 420 stainless steel stem, disc, and seat surface offer superior corrosion resistance. The valve features a flanged connection (DIN EN 1092-2) for easy installation. In addition, the replaceable trim enhances operational continuity.
