ARI-STEVI Bellows seal stem straight through/three way control valve
1）ARI-STEVI Smart 441 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®451 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®471 High cost performance and diversity control valves for harsh operating conditions.
4）ARI-STEVI Vario 449 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.
