installation, operation and maintenance. The operator is responsible for observing the location-specic
safety regulations, also with reference to personnel.
Riskofinjuryfromhighpressure.
Before loosening lines and valves, turn o the pressure and vent the lines!
Riskofburns/reduringcontinuousoperation.
The device can become very hot when dosing hot media.
▶The device regulates hot media and must only be handled with protective gloves.
▶Keep highly ammable substances and media away from the device.
Generalhazardoussituations.
To prevent injuries, ensure that:
▶The housing is not placed under mechanical stress (e.g. by placing objects on it or standing on it).
▶Do not make any external changes to the valve bodies.
▶Do not feed aggressive or ammable media into the pilot air ports of the system.
▶Only the media listed in the chapter “6 Technical data” as ow media should be fed into the uid
connections.
▶Secure the device against unintentional activation.
▶Installation and maintenance may be performed by authorised technicians only and with the appropriate
tools.
▶After an interruption of the electrical / pneumatic supply you must ensure a dened or controlled restart

Structure and function
Type 2080
5 STRUCTURE AND FUNCTION
5.1 Modularity
The device has a modular design and can be supplied with dierent media connections (also customised)
and actuator versions depending on the application.
5.2 Design
The device consists of a pneumatically operated piston actuator with a return spring, a stainless steel
housing and a PTFE bellows. The bellows serves to separate the media.
The materials used and the internal contours allow easy cleaning (CIP/SIP).
The pneumatic actuator must be controlled externally with a pilot valve or a valve island.

6 TECHNICAL DATA
6.1 Operating conditions
Ambient temperature –10 ... +90 °C
Medium temperature –30 ... +160 °C (see PT diagramm)
Flow media Neutral to aggressive gases and liquids, technical vacuum
6.2 Restrictions
For valves with ow direction above the seat:
WARNING!
Riskofinjuryfrompressuresurge.
Pressure surges may occur if liquid media ow direction is above the seat. As a result, lines or equipment
may burst and medium may ow out.
▶Observe the type of ow and type of medium for operating the device.
▶In the case of ow direction above the seat: to avoid pressure surges, clarify the operating conditions
(medium, line length and line cross-section) with the Bürkert sales oce before using liquid media.
6.3 Conformity
The bellows valve type 2080 INOX conforms to the EU directives as per the EU declaration of conformity.
6.4 Standards
The applied standards as used to verify compliance with the Directives can be found in the EC type exami-
nation certicate and/or the EC Declaration of Conformity.
