Intended Use
2. INTENDED USE
The ball valves types 2651, 2654 and 2660 (in general below as "Ball
valves") are intended for the installation to pneumatic or electric rotary
actuators. They can be used indoors as well as outdoors, in compliance
with the permissible operating conditions.
Non-intended use of the ball valves can be dangerous to
people, nearby equipment and the environment.
• The ball valves are used for shutting off media flows in a wide
range of industrial applications.
• The ball valves may be used only in conjunction with third-party
devices and components recommended and authorized by Bürkert.
• During use observe the authorised data and operating conditions
specified in the contract documents and operating instructions
as well as the range of applications described in „5.1. Intended
Application Area“.
• Correct transportation, correct storage and installation and careful use
and maintenance are essential for reliable and faultless operation.
• Use the ball valves only as intended.
2.1. Restrictions
If exporting the System/Device, observe any existing restrictions.
2.2. Predictable Misuse
• Operate the ball valves only with media which do not corrode the
housing or seal material.
• Do not physically stress the housing (e.g. by placing objects on it
or standing on it).
• Do not make any external modifications to the housing.

Basic Safety Instructions
3. BASIC SAFETY
INSTRUCTIONS
These safety instructions do not make allowance for any:
• Contingencies and events which may arise during the installation,
operation and maintenance of the devices.
• Local safety regulations; the operator is responsible for observing
these regulations, also with reference to the installation personnel.
WARNING!
Unintentional activation or non-permitted impairment may
cause general hazardous situations through to physical injury.
To prevent injury, ensure that:
• The system cannot be activated unintentionally.
• Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
• After an interruption in the power supply or fluid supply, ensure
that the process is restarted in a defined or controlled manner.
• The device may be operated only when in perfect condition and
in consideration of the operating instructions.
• The general rules of technology apply to application planning
and operation of the device.
DANGER!
Danger – high pressure!
• There is a serious risk of injury when reaching into the equipment.
• Turn off the pressure and release the pressure in the pipes
before loosening pipes and valves!
CAUTION!
The general rules of technology apply to application planning
and operation of the device!
• Failure to observe these rules may result in injuries and/or dam-
age to the device and possibly the area around it as well.
• Observe the general rules of technology!
NOTE!
The ball valves were developed with due consideration given to
the accepted safety rules and are state-of-the-art. Nevertheless,
dangerous situations may occur.
• Operate the ball valves only when they are in perfect condition
and in accordance with the operating instructions.
Failure to observe this operating manual and its operating instruc-
tions as well as unauthorized tampering with the device release us
from any liability and also invalidate the warranty covering the device
and accessories!

5. SYSTEM DESCRIPTION
5.1. Intended Application Area
The ball valves are used for shutting off media flows in a wide range
of industrial applications.
They are particularly suitable for application conditions which make
high demands in the areas of thermal loads and are also suitable for
applications which use aggressive media.
5.2. Functions
The ball valves for shutting off media flows are available in different
sizes. They are equipped with a mechanical interface as per ISO 5211.
This interface is used to install a pneumatic or electric rotary actuator
to the ball valves.
On request the ball valves can be supplied complete with a
pneumatic actuator (Types 2652, 2655, 8805) or an electric
actuator (Type 8804).

Operation and function
7.2. Installation in the Pipeline
Procedure:
→Check that the pipes which are to be connected to the ball valve are
on one level. This will prevent mechanical tension on the screw joint.
→Screw the ball valve to the pipe.
→Check that the ball valve is firmly attached to the pipe to ensure
appropriate tightness.
8. OPERATION AND FUNCTION
8.1. Safety instructions
WARNING!
Danger due to improper operation!
