Valves for all fields of application
Single seat valves in hygienic and aseptic type
manually or pneumatically operated
- the valves for to overcome the most difficult
tasks -
Technical advantages
As modular assembly system our single-seat
program offers the possibility to combine different valve elements.
Because of their construction our valves got
the American 3A-standard-application. The seat for the upper body sealing
shows the necessary incline and the sealing reaches to the product area.
There is no dome/cupola in the valve body which would be difficult to
clean.

Valve body types
Leakage butterfly valves
manually or pneumatically operated
- for the reliable use as single valve or as valve
manifolds in CIP-plants
- and for the safe separation and against mixing-up with harmful liquids
Funktion
 |
The most important parts
are the butterfly valve and the two small valves. The butterfly valve
regulates the quantity of liquids. As soon as the process in the piping
systems changes and the valve is opened, both the small valves are closed -
liquid can flow.
Both the small valves are used for emptying the
leakage space or for a separated CIP/SIP-cleaning: They are opened as soon
as the butterfly valve closes - then the liquid can flow out of the leakage
space without obstacle.
For to avoid soiling of the springs the spring space
is sealed by an O-ring. The small valves open with a valve inner pression of
more that 10 bars (safety measure). |
Connections
Only the body of the valve
inner part is specially constructed. Other parts are out of series. Many usual
connections are possible. Both the valve flanges mounted to the valve inner part
are out of our standard valve program.
Sampling valves
manually or pneumatically operated
- the solution for your samples -
All of our sampling valves are fitted with PTFE-bellows
granting a hygienically perfect taking of samples.
According to customer's desire they are mounted in arrestable or lockable type.
 |
The shown valves are only few examples. |
Let us know your field of application - we give you our
advice.
For all valves is valid:
Parts in contact with product are made of 1.4404, higher
alloyed stainless steels on request like 1.4435 or Hastelloy, other parts made
of 1.4301.
The inner surfaces are standard 0,8 µm, better inner
surfaces on request.
Valves for traditional/conventional application
A progressive valve design, thousandfold proved in daily
use, guarantees high flexibility within the individual compounds.
Complex valve systems are possible with our
| inclined seat valves |
| right angle valves |
| cross valves |
| change-over valves |
| bottom seat valves |
| check valves |
| overflow valves |
| safety valves |
in manual and pneumatic version. Changeable drive units
allow flexibility in daily use.
