Basic Safety Instructions
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 – 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.
• In the potentially explosion-risk area the angle-seat control valve
Type 2300 may be used only according to the specification on
the separate Ex type label. For use observe the additional information enclosed with the device together with safety instructions for the explosion-risk area.
• Devices without a separate Ex type label may not be used in a
potentially explosive area.
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.

The warranty is only valid if the device is used as authorized in accordance with the specified application conditions.
5.3. Information on the internet
The operating instructions and data sheets for Type 2300 can be found
on the Internet at: www.burkert.com
6. STRUCTURE AND FUNCTION
The angle-seat control valve Type 2300 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 incorporated directly. Via a dowel pin, the control
cone is modularly coupled to the actuator spindle for quick changeovers. 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) generates 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
contributes 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”).

8.3.3. Install control unit
Before installation, check the position of the ports on the
control unit and, if required, align the actuator.
Description see chapter “8.3.4. Rotating the actuator”.
→ Remove collet from pilot air port 1.
→ Check that the O-rings are correctly positioned in the pilot air ports.
→ Align the puck holder and the control unit until
1. the puck holder can be inserted into the guide rail of the
control unit and
2. the supports of the control unit can be inserted into the pilot
air ports of the actuator (see “Fig. 5”).
NOTE!
Damaged printed circuit board or malfunction!
• Ensure that the puck holder is situated flat on the guide rail.

→ Push the control unit, without turning it, onto the actuator until no
gap is visible on the form seal.
NOTE!
Too high torque when screwing in the fastening screw does
not ensure protection class IP65 / IP67!
• The fastening screws may be tightened to a maximum torque of
0.5 Nm only.
→ Attach the control unit to the actuator using the two side fas-
tening screws. In doing so, tighten the screws only hand-tight
(max. torque: 0.5 Nm).

8.3.4. Rotating the actuator
The position of the connections can be aligned steplessly by rotating
the actuator through 360°.
Only the entire actuator can be rotated. The control unit
cannot be rotated contrary to the actuator.
NOTE!
Damage to the seat seal or the seat contour!
• When rotating the actuator, ensure that the valve is in open
position.
Procedure:
→ Clamp the valve body in a holding device (applies only to valves
which have not yet been installed).
→ Control function A:
Without unit control: pressurize the pilot air port 1 with compressed air (5 bar): valve opens.
With unit control: open the valve according to the operating
instructions for the control unit.
→ Counter on the flats of the nipple with a suitable open-end
wrench.
WARNING!
Risk of injury from discharge of medium and pressure!
If the direction of rotation is wrong, the body interface may become
detached.
• Rotate the actuator module in the specified direction only (“Fig. 7”)!

8.4. Pneumatic connection
DANGER!
Danger – high pressure in the equipment!
• Before loosening the lines and valves, turn off the pressure and
vent the lines.
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.
Risk of injury from unsuitable connection hoses!
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
• Use only hoses which are authorized for the indicated pressure
and temperature range.
• Observe the data sheet specifications from the hose
manufacturers.
The pneumatic connection of the angle-seat control valve
can be carried out only in connection with the appropriate
control unit.
Possible control units are:
Positioner Type 8692, 8694, 8696 and 8792;
Process controller Type 8693 and 8793.
8.4.1. Connection of the control medium
→ Connect the control medium to the pilot air port (“Fig. 8”: 1)
(3 – 7 bar; instrument air, free of oil, water and dust).
→ Fit the exhaust line or a silencer to the exhaust air port (“Fig. 8”:
3) and, if available, to the additional exhaust air port (“Fig. 8”: 3.1).
If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.
