STEVI Vario – the new, variable, compact control valve!
The new “Vario” has 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.
The “Vario” extends the existing STEVI range consisting of STEVI Smart (Series 440/441) – the classic standard valve for universal applications – and STEVI Pro (Series 470/471) – the highperformance control valve for critical applications.
Long life: stem seals already proven millions of times over, service life now further extended (PTFE V-ring sealing units and EPDM linings) Optimum handling: upper part can be rotated 360° Flexible: changeable, variable trim (at least 4 Kvs values as well as multiple flow characteristics and plug designs) Precise and durable: vibration is prevented even at high differential pressures (stable shaft guiding) Easy handling: small footprint and reduced weight (low height) Economical: very low air consumption (smaller pneumatic actuators on request)
