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.


4/6

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.
