3 INTENDEDUSE

Unauthorised use of the Type2301 globe control valve may be

dangerous to people, nearby equipment and the environment.

▶The device is designed to control the ow of liquid and gaseous

media. It can only be operated in combination with a corre-

sponding control unit.

▶In potentially explosive environments, the Type2301 globe control

valve must only be used in accordance with the specications on

the separate Ex-type label. The additional information and safety

instructions relating to Ex areas enclosed with the device must

be adhered to when deploying the device.

▶Devices without a separate Ex type label must not be used in

the potentially explosive atmosphere.

▶To use the device, observe the permitted data, operating con-

ditions and application conditions. These specications can be

found in the contract documents, the operating instructions and

on the type label.

▶Prerequisites for safe and trouble-free operation are correct

transport, correct storage and installation as well as careful

operation and maintenance.

▶Use the device only in conjunction with third-party devices and

components recommended or approved by Bürkert.

▶Use the device only as intended. Non-intended use of the

device may be dangerous to people, nearby equipment and the

environment.

▶Protect device from harmful environmental inuences (radiation,

air humidity, fumes, etc.). For any matters requiring clarication,

contact the relevant sales department.

Type2301

4 BASICSAFETYINSTRUCTIONS

These safety instructions do not take account of any

•contingencies or events which may occur during installation,

operation and maintenance of the devices;

•local safety regulations that are within the operator’s scope

of responsibility, including those relating to the installation

personnel.

DANGER!

Risk of injury due to high pressure and escaping medium!

▶Before working on the system or device, switch o the pres-

sure and vent or empty the lines.

Risk of injury due to electric shock. (with installed electrical

components)

▶Before working on the device or system, switch o the

power supply. Secure against reactivation.

▶Observe the applicable accident prevention and safety regu-

lations for electrical devices.

WARNING!

Risk of injury when opening the actuator!

The actuator contains a spring under tension. When the actuator is

opened, the spring will jump out and may cause injuries.

▶Do not open the actuator.

Risk of injury due to moving parts in the device!

▶Do not reach into openings in the device.

Danger due to loud noises.

▶Depending on the usage conditions, the device may generate loud

noises. Detailed information on the probability of loud noises is

available from the respective sales department.

▶Wear hearing protection when in the vicinity of the device.

CAUTION!

Risk of burns or re from hot device surfaces due to pro-

longed operation.

▶Only touch the device when wearing protective gloves.

▶Keep the device away from highly ammable substances and

media.

Discharge of medium if packing gland exhibits wear

▶Relief bore must be regularly inspected for any medium leakages.

▶If the medium is hazardous, secure the area around the leakage

to prevent risks.

General hazardous situations.

To prevent injuries, observe the following:

▶Secure device or system to prevent unintentional activation.

▶Only trained technicians may perform installation and main-

tenance work.

▶Perform installation work and maintenance work using suit-

able tools only.

English

General notes

Type2301

▶Following interruption of the process, ensure that the

process is restarted in a controlled manner. Observe the

sequence:

1. Apply electrical or pneumatic supply.

2. Charge with medium.

▶Use the device only when it is in perfect condition and in

accordance with the operating instructions.

▶For applications planning and operation of the device, observe

the plant-specic safety regulations.

▶The plant owner is responsible for the safe operation and

handling of the plant.

▶Observe the general rules of technology.

Please observe the following in order to protect against

damage to the device:

▶Feed only those media listed in chapter “7 Technical data” into

the medium ports.

▶Do not place the valve under mechanical stress (e.g. by placing

objects on it or standing on it).

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

paint housing parts or screws.

▶The exhaust air can be contaminated by lubricants in the

actuator.

▶Transport, install and remove heavy device only with the aid of

a second person and using suitable tools.

Structure and function

Type2301

6 STRUCTUREANDFUNCTION

The Type2301 globe control valve can only be used in

combination with the following control units:

Positioner Type8692, 8694, 8696 and8792

Process controller Type8693 and8793

6.1 Structure

The valve seats are screwed in. Reduced seat sizes are simple to

achieve by replacing the screw-in seats. The ow direction is always

below the valve seat.

6.2 Function

The valve seat is always closed against the medium ow. Spring

force (CFA) or pneumatic pilot pressure (CFB and CFI) generate

the closing force on the control cone. A spindle connected to the

actuator piston transmits the force.

6.2.1 Controlfunctions(CF)

WARNING!

For control function I – risk of pilot pressure failure!

With control functionI, the control unit and reset are pneumatic.

No dened position is reached during a pressure failure.

▶To ensure a controlled restart of the device, rst apply pilot

pressure and then activate the medium.

Closed by spring force in rest position.

Opened by spring force in rest position.

Actuating function via reciprocal pressurisation

6.2.2 Flowdirectionbelowseat

Depending on the variant, the valve is closed against the medium

ow either with spring force (CFA) or pilot pressure (CFB and CFI).

Because the medium pressure is below the control cone, it helps

open the valve.

WARNING!

Valve leak if there is too little minimum pilot pressure or high

medium pressure!

Minimum pilot pressure for CFB and CFI that is too low, or failing

to meet the permitted medium pressure, can cause a leak in the

valve seat.

▶Adhere to minimum pilot pressure.

▶Do not exceed the medium pressure (see chapter “Pressure

ranges”).
