Type 2301
4 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.
DANGER!
Danger – high pressure!
▶Before loosening the lines and valves, turn off the pressure and
vent the lines.
Risk of electric shock!
▶Before reaching into the device, switch off the power supply
and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations
for electrical equipment!
Risk of burns!
The surface of the device may become hot during long-term
operation.
▶Do not touch the device with bare hands.
Risk of injury from moving parts in the device!
▶Do not reach into openings.
Risk of injury when opening the actuator!
The actuator contains a tensioned spring. If the actuator is opened,
there is a risk of injury from the spring jumping out.
▶The actuator must not be opened.
General hazardous situations.
To prevent injury, ensure that:
▶The system cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorised
technicians only and with the appropriate tools.
▶After an interruption in the power supply or pneumatic 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.
To prevent damage to property of the device, ensure:
• Supply the media connections only with those media which are
specified as flow media in the chapter entitled “Technical data”.
• Do not put any loads on the valve (e.g. by placing objects on it
or standing on it).
• Do not make any external modifications to the valves. Do not paint
the body parts or screws.

5.2 Warranty
The warranty is only valid if the device is used as authorized in accor-
dance with the specified application conditions.
5.3 Information on the internet
The operating instructions and data sheets for Type 2301 can be found
on the Internet at: www.burkert.com
6 STRUCTURE AND FUNCTION
The globe control valve Type 2301 can be operated only 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. A reduction in the orifices of the seats
can be achieved by simply exchanging the threaded seats. The flow
direction is always below seat.
6.2 Function
The seat of the valve is always closed against the medium flow.
Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) gen-
erates the closing force on the control cone. The force is transferred
via a spindle which is connected to the actuator piston.
6.2.1 Control functions (CF)
WARNING!
For control function I – Danger if pilot pressure fails!
For control function I control and resetting occur pneumatically. If
the pressure fails, no defined position is reached.
▶To ensure a controlled restart, first pressurize the device with pilot
pressure, then switch on the medium.

6.2.2 Flow direction below the seat
Depending on the version, the valve is closed against the medium
flow with spring force (control function A, CFA) or with pilot pressure
(control function B or I, CFB or CFI).
As the medium pressure is under the control cone, this pressure con-
tributes to the opening of the valve.
WARNING!
Medium may be discharged if minimum pilot pressure is too
low or medium pressure too high!
If the minimum pilot pressure is too low for CFB and CFI or the
permitted medium pressure is exceeded, leaks may occur.
▶Observe minimum pilot pressure.
▶Do not exceed medium pressure (see chapter “Pressure ranges”).
