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

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)

Plug design Parabolic plug / perforated plug
Nominal diameter DN 15-100
Nominal pressure PN 16-40
Actuators Electric or pneumatic
Body materials e.g. EN-JL1040, EN-JS1049, 1.0619+N, 1.4408

SAFE Combi-C / REYCO® Combi-C / SAFE Combi-R

Changeover valves and rupture discs: 100 % stand-by security – even for critical media!

Advantages of a combination safety valve with a changeover valve:

  • cost saving due to service without plant downtime
  • no loss of medium due to exchange of safety valve
  • minimization of risks of hazardous media
  • in service case: only lowest disposal costs for critical media
  • combination of inlet and outlet with a change over valve minimizes a risk caused by hazardous media
  • cost saving due to an additional change over valve in the outlet so that only one outlet pipe is necessary

Advantages of a rupture disc:

  • Cost saving due to absolute tightness (no loss of medium)
  • Due to zero leakage it is possible to use extremely toxic or flammable media
  • Use of media that become solid with contact to the atmosphere, stick together seat / disc or react chemically
  • Cost saving because the production progress can be continued
  • only small loss of medium.
  • Saving of disposal costs in the blow down system
  • Saving of material costs when aggressive media do not allow the use of the standard materials
