Aseptic valves

With its new modular system of parts for aseptic valves, Evoguard offers the right components for all applications within the aseptic process.

Safety first

Microbiologically sensitive products need to be treated with special care. The highest safety along the entire product handling chain is needed to guarantee that quality and shelf life will leave no grounds for complaint.

With its new modular system of parts for aseptic valves within the Evoguard valve range, Krones now offers the right components for all applications within the aseptic process. The new concept underlying these aseptic valves is based on extensive tests, which were carried out under production conditions in the valve technology field, and on the use of modern methods of analysis and engineering design. With this 

data in particular it has been possible to realise optimised details of design on all components. For you this means not only top performance from the individual components but also coherent concepts for your process as a whole.

 

Valves for shutting off

Aseptic seat valve SA

  • Shutting off pipes in aseptic and sterile processes

    With the aseptic seat valves, Evoguard offers the right components for all applications within the aseptic process.

  • Actuator allocation according to product pressure
    • 6 bar
    • 10 bar
  • Housing design for a smooth product transition
  • PN 25 housing designed for optimal cleaning
  • Two-piece or one-piece valve disk available
    • Two-piece threaded valve disk with defined clearance for the sealing rings for easy installation and for security against infiltration and the seal being torn out
    • One-piece valve disk with PTFE compound sealing ring
  • Leakage drain/bellows monitoring connections
  • Rotational decoupling on linkage between valve shaft and drive for torsion-free lift motion of the valve disk
  • Bellows with support
    • Stop for disassembly to prevent overstressing of the bellows; moreover, the support reduces vibrations and increases the service life of the bellows

Valve for aseptic shut-off and blocking

Aseptic double seat valve MA

  • Separation of incompatible media in aseptic and sterile processes

    Evoguard aseptic double seat valves are a reliable node for connecting the individual pipe systems.

  • Safety during lifting of the bottom valve disk by means of locking the top valve disk with compressed air
  • Clear cross sections without reduction of the passage
  • Support analogue to the aseptic seat valve
  • Leakage chamber with angular flushing valve
    • Direction of flow of the cleaning liquid diagonal to the bellows
    • Turbulence in the safety chamber
  • Actuator with integrated cycle functions
    • For fast cycle times and low air consumption

  • Final control element allocation according to product pressure: up to 10 bar
  • Rotary connection to tank flange
  • Clear cross sections without reduction of the passage
  • Leakage chamber with angular flushing valve
    • Direction of flow of the cleaning liquid diagonal to the bellows
    • Turbulence in the safety chamber
  • Final control element with integrated timing functions:
    • Fast cycle times
    • Low air consumption

Sampling

Sampling valves and systems

Safe and sterile withdrawal of product samples in the aseptic area

  • Design as fixed valve or as flexibly applicable sampling system
  • Valve version with tank connection stub, welded end or for inline installation
  • PTFE-TFM 1705 bellows seal
  • Actuation variants: Pneumatic actuator, automatically closing manual lever or with handwheel for fine adjustment
  • Monitoring: optional use of a proximity switch
