ARI-STEVI Spring loaded PTFE-V ring seal straight through/three way control valve 
1）ARI-STEVI Smart 440 Control valve is for variable industrial applications control systems,steam seal can be flexibly selected, rolling seat ring design based on economic considerations.
2）ARI-STEVI 450 Three-way control valves,the design of mixing/diverting valve head can solve the problem of fluid confluence once and for all.
3）ARI-STEVI 470 High cost performance and diversity control valves for harsh operating conditions.
4）ARI-STEVI Smart 445/446 Control valve is for variable control systems of industrial applications. A straight through type regulator/control valve with the option of independently replacing the threaded seat and stem design based on flexibility considerations.
5）ARI-STEVI Vario 448 Control valve uses a variable actuator design and is incredibly flexible thanks to the changeable, variable trim. It is precise and durable because vibration is prevented even at high differential pressures. The extended service life is a further advantage.
