Filling valve - aseptic

 



PTFE Bälge für Rieger Einsitzventil
 

suitable for liquid, fibrous and particulate products such as yogurt, soups with meat deposits, strawberry jam 

  • housing made of solid material
  • perfectly cleanable
  • inner surface Ra <= 0,8 µm (standard)
  • product space hermetically separated against ambient
  • sizes from DN 10 to 40 available
  • completely emptying/draining
  • dead space free design
  • product-protecting sterile media guidance
  • easy and quick installation without special tools
  • low downtime
  • FDA-compliant
  • long service life through enhanced pressure stability (up to 10 000 000 operations )
  • folds remain open in open position, therefore easily cleanable
  • large stroke, therefore also suitable for fruit pieces (whole cherries or strawberries at DN 20 DIN)
  • fast acting actuator (up to 2 full cycles/second at DN 20 DIN or 3/4" or reacting time of < 200 ms)
     

The long service life of the PTFE bellows, optionally available with stainless steel cap or PEEK cap for liquids with grains, ensures low downtime.

Because of open folds in the open state, the cleaning performance is optimal.

Several valves, combined to valve blocks in filling machines, aseptically fill up products like yogurt.

Areas of Rieger filling valves
Different manufacturers worldwide rely on technology Rieger:

  • A renowned mustard manufacturer from Germany relies on Rieger..
  • Rieger valves fill liquid soap in plant of a multinational corporation.
  • A large dairy in England fills fruit yogurt with fruit pieces .
  • and many more ...
 

Our service for you

For filling processes we start where others stop. Our engineers develop solutions for your needs. You do not need to change your existing process - we adapt our valves to your process. Make an appointment with one of our sales representatives for a free consultation on site . We also modify existing plants.

As with all applications, there are different philosophies. Some products, for example Yogurt in cups or baby food in the glass, are filled from the top into the vessel (over level). Others are filled by a lance just above or even below levels as salad dressing or shampoo .

For all these applications Rieger designed and built valves. Below some examples:
 

 
  1. Inclined seat filling valve for liquid/fibrous/granular filling media

 
 
  • nominal size DN 10-DN 20 (others on request)
  • available as fast actuator (<200msec)
 
   
     
 
  1. 'Bottom' seat filling valve for liquid/fibrous/granular filling media
 
 
  • Nominal size DN 25-DN 40 (others on request)
  • fast actuator available (a bit slower in comparison to the above shown!)
 
   
     
 
  1. Right Angle Filling valve with resp. for filling lance
 
 
  • Nominal size DN 10-20 (others upon request)
  • as fast actuator available
 
   
     

Best quality of your products in the entire production process is the utmost
importance for you. Why you should stop while filling?

A more efficient production and higher productivity by higher output is
possible by faster and higher switching times.

The durability of the PTFE bellows reduces production losses by
reduced downtime.
