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.

Basic safety instructions
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.

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.

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.

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”).
