STEVI® Vario - Complete solution, endless possibilities!

The new variable, compact control valve – 100,000 variants –
Shipped within 48 hours!*

Profit from the new diversity of the STEVI® Vario. The changeable, variable trim enables bespoke product solutions tailored to individual customer requirements (different screwed seat rings for optimal Kvs values and plug designs)!

Maximum installation flexibility is guaranteed, even in tight spaces, owing to the smaller height and lower weight – up to 25% in each case –  and the fact that the upper part can be turned 360°. You can order your Vario with either electric or pneumatic ARI actuators.

*Standard versions

STEVI® Vario – the new, variable, compact control valve!

  • 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)
