STEVI® Pro – The high-performance control valve for professional control especially in critical applications

The high-performance control valve now also available in pressure ratings from PN 63 to PN 160 and ANSI Class 600 in cast steel and stainless steel body materials.

  • Precise and high performance: optimised characteristic quality.
  • Variable: due to various reducible KVS values.
  • Variable: stem seal options (PTFE V-ring unit, PTFE packing, graphite packing, stainless steel bellows seal, EPDM lining).
  • Variable: changeable trim.
  • Minimal noise: multi-stage trim (optional).
  • Safe: blow-out proof stem.
  • Safe: shaft guided plug.
  • Safe: two-ply bellows seal (optional).
  • Long life: precision stem guiding.
  • Precise: even better control accuracy (optimised flow paths).
  • Flexible: due to high differential pressure ratios.
