Ari Armaturen STEVI Vario Control Valve (Flanged PN40, Cast Steel Body, Electric Actuator)

The STEVI Vario Control Valve with PN40 flanged connections, a cast steel body, and an electric actuator is built to provide high-precision control of flow, pressure, and temperature across demanding process systems. Designed for continuous modulation, this valve offers smooth, accurate regulation for steam, gases, and liquids in high-pressure environments.

Constructed from robust cast steel, the valve body offers excellent mechanical strength and temperature resistance, making it ideal for industrial process control in power plants, chemical plants, HVAC systems, and steam networks. The PN40 flange rating ensures safe operation in high-pressure systems, while the integrated electric actuator delivers precise, automated control — eliminating the need for manual intervention and allowing for integration with control systems such as PLCs and DCS platforms.

The Ari Armaturen STEVI Vario’s internal components are engineered for reliability, with tight shut-off performance and low hysteresis. Its modular design allows for easy maintenance and adaptation to changing system requirements.
