ARI-Armaturen Control Valves
ARI STEVI control valves for steam, thermal oil and process duty, sized on Kvs and the actual process curve with matched actuation.

Request a QuoteARI STEVI control valves regulate flow, pressure or temperature rather than simply opening and closing, so they are sized on Kvs and the actual process curve rather than on line size. Getting the trim wrong produces cavitation, noise and premature seat wear.
The actuator follows from the valve: required thrust or torque, fail position, and whether control is pneumatic, electric or self-acting.
Send the line size, pressure class, medium, temperature, flow range and required fail position, or the ARI figure number if you are replacing like for like.
Applications
- Steam pressure and temperature control
- Thermal oil regulation
- Process heating and cooling loops
- Actuated shut-off duty
