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.

Highpressuredanger!
Acute risk of injury when intervening with the system.
▶Before loosening lines and valves, turn o the pressure and vent the lines.
Check that the operating conditions comply with the performance data of the device.
7.1.1 Installation position
The installation position is arbitrary. Preferably actuator face up.
7.1.2 Prior to installation
→Clean any dirt from the pipelines and ange connections.
→If necessary, install a strainer upstream of the valve to protect against malfunctions.

Installation
Type 2080
7.1.3 Installation
WARNING!
Dangerduetomediumleakage.
Leaky connections with incorrect seating of the seals.
▶Install all connections carefully and make sure the seals are seated properly.
Use suitable sealing material to seal the threaded connections (PTFE tape is recommended).
For threaded connections: Use open-end wrenches of the appropriate size to screw in the pipelines
and do not use the valve actuator as a screw-in lever.
No lateral bracing forces may act on the connections of the device. The device connections and
cables must be tidy.
→Fasten the valve according to the selected connection type:
Threaded connection by screwing in the pipes, welded connection by welding, ange connection by
screwing in.

8 MAINTENANCE, MALFUNCTIONS
DANGER!
▶Danger due to high pressure in the system.
Acute risk of injury when intervening in the system.
▶Before loosening lines and valves, turn o the pressure and vent the lines.
Riskofinjuryfromdischargeofpressureandescapingmedium.
Dismantling a device that is under pressure is hazardous due to a sudden discharge of pressure or
escaping medium.
▶Before disassembly, shut o the pressure and vent all lines.
▶Empty the lines completely.
WARNING!
Riskofinjurythroughimpropermaintenance.
Improper maintenance may result in injuries as well as damage to the device and its surroundings.
▶Maintenance work may only be carried out by authorised specialist personnel and with suitable tools.
Dangerduetounintentionaloperationofthesystem.
Unintentional restarting of the unit during maintenance and repair work can lead to injuries and damage to
property.
▶Take appropriate measures to prevent the system from being operated unintentionally.
8.1 Maintenance / cleaning
The bellows between the medium chamber and the actuator enables functionally reliable switching of the valve
and protects the medium from contamination from the actuator side.
This bellows is subject to fatigue. If the bellows is defective, medium leaks out of the opening for leakage control.
To avoid damage, the bellows should be replaced preventively on a regular basis (see chapter “8.2 Change
bellows”).
The valve is designed without gaps on the inside and with very smooth contours on the interior as well as on the
bellows (surface roughness max. 0.8 µm).
The valve is CIP-capable (CIP = cleaning-in-place) and SIP-capable (SIP = sterilisation-in-place).
8.2 Change bellows
Disassembleactuator
→Have the necessary spare parts and an open-end wrench SW 7 ready.
→ Observe safety instructions!
→Loosen fastening screws
→Remove actuator.

Maintenance, malfunctions
Type 2080
Changebellows
→Unscrew the bellows from the spindle.
→Clean the inside of the valve body.
→Screw the new bellows onto the spindle with two ngers until it stops (tightening torque approx. 0.2 Nm;
too much tightening torque can damage the bellows!).
Installactuator
→Clean O-ring 25 x 2 FKM 70, check for reusability. Replace with new O-ring if necessary.
→Place the actuator with the new bellows on the housing and fasten it to the housing with the fastening
screws. Observe a tightening torque of 2 to 2.2 Nm at .
Restartingthebellowsvalve
→Connect the pilot air line.
→Open the pilot air.
→Open the media supply.
→Carry out a function and leak test.
→If it functions safely, the valve can be put back into operation.
