Description

ARI-Armaturen STEVI 405 Globe-Type Control Valve with Pneumatic Actuator

The ARI-Armaturen STEVI 405 is a robust and versatile globe-type control valve designed for precise flow regulation in industrial process systems. Engineered in Germany, it is equipped with a pneumatic actuator (tag: WB-XV-590) for reliable control in both modulating and ON/OFF applications. This valve features a soft NBR seal, offering excellent compatibility with water, light oils, air, and industrial fluids, and ensures Class VI tight shutoff.

Constructed from EN-GJL-250 (cast iron) or EN-GJS-400-15 (ductile iron), the valve body is paired with internal trim components in stainless steel or bronze/brass alloy, depending on fluid compatibility. The valve supports linear or equal percentage flow characteristics and includes flanged ends in accordance with EN 1092-2 for easy integration into PN16 piping systems.

With a design pressure of 16 bar and service temperatures up to 100°C, this valve is ideal for HVAC, steam, and general utility service. The actuator supports standard pneumatic signals (3–15 psi) or can be configured with an electro-pneumatic positioner. Optional features include limit switches, solenoid valves (NAMUR interface), and fail-safe (open or close) spring-return configurations.
