Intended use

2 INTENDED USE

The ball valves types 2651, 2654, 2654 Hygienic, 2660 and

TKU001/2/3 (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 permis-

sible 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 o media ows 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

specied in the contract documents and operating instructions

as well as the range of applications described in „5 System

Description“.

▶Correct transportation, correct storage and installation and

careful use and maintenance are essential for reliable and

faultless operation.

▶Operate the ball valves only with media which do not cor-

rode the valve body or seal material.

▶Use the ball valves only as intended.

CAUTION!

Warns of a possible danger.

▶Failure to observe this warning may result in a medium or

minor injury.

NOTE!

Warns of damage to property.

▶Failure to observe the warning may result in damage to the

device or the equipment.

Indicates important additional information, tips and

recommendations.

Refers to information in these operating instructions or in

other documentation.

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 uid supply,

ensure that the process is restarted in a dened or controlled

manner.

▶The device may be operated only when in perfect condition

and in consideration of the operating instructions.

▶Do not physically stress the valve body (e.g. by placing

objects on it or standing on it).

▶Do not make any external modications to the valve body.

▶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 o 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

damage to the device and possibly the area around it as well.

▶Observe the general rules of technology!

NOTE!

▶Operate the ball valves only when they are in perfect condi-

tion and in accordance with the operating instructions.

General information

5 SYSTEM DESCRIPTION

The ball valves are used for shutting o media ows 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.

The ball valves are available in dierent sizes. They are equipped

with a mechanical interface as per ISO 5211 which is used to install

a pneumatic or electric rotary actuator.

On request the ball valves can be supplied complete with a

pneumatic actuator (Types 2652, 2655, 8805) or an electric

actuator (Type 8804).

Installation

7 INSTALLATION

DANGER!

Risk of injury from high pressure in the equipment.

There is a serious risk of injury when reaching into the equipment.

▶Turn o the pressure and release the pressure in the pipes

before loosening pipes and valves.

WARNING!

Risk of injury due to improper installation.

Improper installation may result in injuries as well as damage to

the device and the area around it.

▶This work may be carried out by authorised technicians only

and with the appropriate tools.

Risk of injury due to unintentional activation.

Hazardous situations may arise due to unintentional activation

of the system.

▶Take appropriate measures to prevent the equipment from

being unintentionally activated.

7.1 Ball valve with screw thread

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 rmly attached to the pipe to ensure

appropriate tightness.

7.2 Ball valve with welded connection

NOTE!

To prevent damage to the ball valve and the contained seal,

disassemble the ball valve from the pipeline prior to welding.

Disassembling the ball valve:

→Undo the four body bolts and disassemble the ball valve into

three parts.

→Remove the seal from the connection element.

→Weld the connection element to the pipeline.

→ Assemble the ball valve and x it into position using the four

body bolts!

Make sure the seals are seated correctly!

Refer to the following table for tightening torques!

Welding of the ball valve Type 2654 Hygienic is possible

under the following conditions:

•Orbital welding using orbital welding equipment.

•The heat impact on the seals must not exceed the

maximum temperature. The maximum temperature for

the stainless steel valve body is +200 °C.

Operation and functions

8 OPERATION AND FUNCTIONS

WARNING!

Danger due to improper operation.

Improper operation may result in injuries as well as damage to

the device and the area around it.

▶The operating personnel must know and have understood

the contents of the operating instructions.

▶Observe the safety instructions and intended use.

▶Only adequately trained personnel may operate the equip-

ment/the device.

8.1 Operation

Via the mechanical interface as per ISO 5211, the ball valves can

be connected to a pneumatic rotary actuator (e.g. Types 2050,

2051 or 2052) or an electric rotary actuator (e.g. Types 3003,

3004 or 3005).

The operating instructions of the actuators you can nd on the

Bürkert homepage: www.burkert.com

NOTE!

If the seals are exposed to a temperature greater than the

maximum temperature during the welding process, all the

seals must be replaced with new ones.
