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!

Improper operation may result in injuries as well as damage to the
