Quarter-Turn Ball Valve Systems

for normal and slightly aggressive fluids

Type 2651...56

Manual / Pneumatic / Electric

DN 10 up to 50 mm; stainless steel

Advantages/Benefits

Applications

The ball valve family type 2651...56 is

designed for any kind of application

in the process industry.

The ball valve consists of two

variable modules, the valve body

and the actuator.

Two body designs both in stainless

steel are available as follows:

• The two-piece valve body is the

economic solution in applications

with low cycle rates and uncritical

sealing conditions, slow and few

changes of pressure and tempe-

rature of the fluid.

• The three-piece valve body for

industrial applications is specifi-

cally equipped with a two level

sealing system to get superior

tightness in the stem area during

temperature and pressure variati-

ons. Maintenance and changes

of seals and seat can be done on

line, while keeping the valve on

the pipe.

Fluid Control Systems

Integrated pilot valves,

position feed-back and limit

switches available

Customized system solutions

with Burkert valves & sensors

With ASI-bus interface

-Namur valves as pilots

available

Fluids

• Neutral gases and fluids

• Ultrapure water

• Slightly aggressive fluids

• Slightly contaminated liquids

Applications

• Water treatment / ozoning

systems

• Slow processes / tank farming

in beverage and pharmaceutical

industry

• Shut-off armatures in chemical

and dyeing industry

• Textile machines

Design/Function

The quarter turn for opening the

valve can be done by a hand lever,

by a pneumatic actuator or by a

compact high performance electric

actuator, which all can be used on

the two-piece and on the three-piece

valve body, depending on the

application and on the kind of control

of the process.

This modular concept allows to

build up a ball valve for any degree

of automation and any kind of

application in the process industry.

A system can be completed with

pilot valves for the operation of the

pneumatic actuator, a compact

position feedback, a control head,

optional with ASI-bus, for ON/OFF

control functions and an on-place

stand-alone controller (position

control or process control) for

continuous control processes.

An Easy Link can be built up with

any kind of sensor. The electric

motor actuator has a standard

signal input (4...20 mA) to be

connected and controlled directly

by a PLC.
