Incorrect use of the bellows valve Type 2080 can be
dangerous to people, nearby equipment and the en-
vironment.
The device is designed for the controlled flow of liquid•
and gaseous media.
For use observe the permitted data, operating and ap-•
plication conditions which are described in the contract
documents as well as on the type plate and in the oper-
ating instructions in the chapters entitled “Structure and
Function” and “Technical Data”.
The device may be used only in conjunction with third-• party devices and components recommended and au-
thorised by Bürkert.
Correct transport, correct storage and installation and • careful use and maintenance are essential for reliable and

The valve consists of a pneumatically actuated piston actuator
with return spring, a stainless steel body and PTFE bellows.
The bellows are used to separate media. If the installation
location is appropriate, the valve is self-draining.
The materials used and the inner contours facilitate cleaning
(CIP/SIP).
The pneumatic actuator must be controlled externally via a
pilot valve or a valve island.

gradient of 1° for drainage of media).
Installation
Before installation, clean any possible dirt off the pipelines

The bellows situated between the medium compartment and
actuator ensure that the valve switches reliably and protect
the medium from contaminants coming from the actuator
side. These bellows are subject to symptoms of fatigue. If
the bellows are defective, medium will escape out of the
leakage detection opening. To prevent them from being de-
stroyed, the bellows should be changed prophylactically at
regular intervals (see instructions on changing the bellows).
The valve interior has no gaps and the inner compartment
and bellows have been designed with very smooth contours
(surface roughness max. 0.8 µm). The valve is CIP compat-
ible (CIP = cleaning in process) and SIP compatible (SIP =
sterilization in process).
