Control module systemVARIVENT / T.VIS,also available with stain-less steel feedback switchholder
Actuator system with liftfunction, easy to main-tain.
Lift stroke limited by ametallic stop in the actua-tor (no adjustment requi-red).
Connections provided for:
Bellows monitoring
Bellows rinsing
Leakage indication anddrainage
Sturdy, one-piece valvehousing
SIP shut-off valves withstainless steel feedbackswitch holder, alsoavailable withECOVENT control
module.
Temperature monitoring of
the cavity chamber by contact
sensor Pt-100 (Option).
Core element of the
STERICOM Double Seal
Valve is the one-piece
metal bellows with double
radial sealing.
It stands out with its high
pressure and temperatureresistance. The integrated
valve stem protects the
metal bellows against late-
ral flow.

STERICOM Double Seal Valves are equipped a with
one-piece valve disk (metal bellows) and double
radial valve seats. This innovative valve seat configu-
ration allows for valve actuation using a single-
acting, pneumatic actuator with One-Spring-
Technology.
The advantages of this new technology are simple:
High operational and maintenance safety due double
radial valve seats. When removing the valve's upper
part there is no spring tension released.
Availability of the full spring force at the valve seats
during the valve's rest position as well as during the
cleaning phase when lifting.
Enhanced safety against unintentional lifting of the
upper valve seat during the lifting operation due tofull spring force.
No bellows inside the cavity chamber, bellows
provided for the upper process pipe only.
Resistance to water hammers in the cavity chamber
due to one-piece valve disk and pressure compensa-
ting surfaces.
Small cavity chamber volume, cavity chamber is easy
to clean due to smooth surfaces.
Metallic throttling gap at the valve seats ensures that
during the lifting phases the inlet cross section into the
cavity chamber is smaller than the outlet cross sectionat the rinsing valve - thus preventing pressure build-
up in the cavity chamber.

Quality factor Surfaces
In sterile process applications high quality surfaces are
the main requirement for a safe and reliable process.STERICOM Double Seal Valves are produced with an
inside roughness of Ra < 0.8 m in the product wetted
area, the outside surface is polished. High quality surfa-
ces are available on demand.
STERICOM Double Seal Valves can also be used in
clean-room conditions.
Reproducible manufacturing quality
another quality factor
STERICOM Double Seal Valves are subjected to the hig-
hest quality criteria in the production and fulfil the vali-
dation conditions of plants and process systems.Tuchenhagen takes as a basis the certified quality safety
system according to DIN ISO 9001. Permanent quality
examinations in the manufacturing as well as the certifi-
cation of all products are the proof for the high quality
level and guarantee a fast and safe traceability of spare
parts demands.
Hygienic exterior design
STERICOM Double Seal Valves are of a hygienic exteri-
or design. The design of the closed lantern and the
liquid
draining surfaces without cavities or gaps ensure a con-
stant, hygienic valve exterior.
Simple handling for service and maintenance
During the development special attention was paid to
easy and quick service and maintenance work on site.
Standard tools will be required only when changing thebellows, dismantling the valve actuator or in case of
modification of the SIP shut-off actuators for a reverse
function.
