Valve Housing
Housings for shut-off valves are available in standard
or bottom-seat variants with two or three port
connections each. A change-over valve contains two
housings. The lower housing is available with two or
three port connections and the upper housing with
one or two port connections. The valves are produced with standard butt-weld connections by default.

t capable, up to +160°C (+320°F)
-t Suitable for applications with caustic /
t toxic products

Design Characteristics
-t Modular design, consisting of the three main
t components: housing, internal assembly, and
tactuator
-t The actuator and internal assembly are connected
t to the housing with a three-piece clamp
-t Low-maintenance, service-friendly, and hygienic
tdesign
-t All product contact surfaces are made of AISI 316L
t stainless steel (materials certificate available upon
t request) with a surface finish of 0.8 μm Ra that
t meets all common hygienic standards
-t Complete actuator made of stainless steel
-t Customer-specific materials and surface finishes
t available upon request
-t Valve connections can be provided with aseptic
t flanges, screw connections, or clamps

Functionality
Aseptic shut-off valves are used for the monitored
control of fluids in aseptic processing plants.
A welded stainless steel folding bellow is used to
hermetically seal the valve spindle from outside
contamination. This special design and the durable
valve seat seal made of Tefasep® enables optimum
process security. Aseptic change-over (divert) valves
have similar design features and are used for the
monitored shut-off and change-over of branched
pipelines.

Actuator
The standard version of the pneumatic actuator is
designed as spring-closing / air-opening (NC). Other
available options include: air-closing / spring-opening (NO), air-closing / air-opening (LL), or with additional venting function (AZ). In addition, both valve types are available with a manual actuator (HK).
