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.

The extended service life is a further advantage. It is precise and durable because vibration is prevented even at high differential pressures. The new “Vario” has a variable actuator design and is incredibly flexible thanks to the changeable, variable trim. STEVI Vario – the new, variable, compact control valve!

Optimised characteristic permits shut-off and control function.

Elastic stainless steel and graphite sealing ring.
