2 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 or the equipment, switch off the power supply and secure to prevent
reactivation!
▶ Observe applicable accident prevention and safety regulations for electrical equipment!
Risk of burns/risk of fire if used continuously through hot device surface!
▶ Keep the device away from highly flammable substances and media and do not touch with bare hands.
General hazardous situations.
▶ The system cannot be activated unintentionally. ▶ Installation and repair work may be carried out by authorized 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.

When the spindle opening is exposed, the individual parts of the packing gland are pressed out at an undefined speed when the control air connection is pressurized.
▶ Before pressurizing with control air, safeguard the ambient area of the discharge opening (e.g. place spindle
on a firm base).

Conversion of control function
7 CONVERSION OF CONTROL FUNCTION
7.1 Description of the functions
Depending on the version, the seat of the valve is closed with or against the medium flow. Spring force (CFA) or pneumatic control pressure (CFB and CFI) generate the closing force on the swivel plate. The force is transferred via a spindle which is connected to the actuator piston.
The exact description of the control functions can be found in the operating manual for Type 2000 under:
www.burkert.com.
7.1.1 Control function A (CFA)
In rest position, the valve is closed by spring force. By pressurizing the lower control connection, the seal is lifted from the seat and the flow-through is enabled. The open status is displayed by a position indicator located in the cover of the actuator.
7.1.2 Control function B (CFB)
When not under pressure, the valve is opened by the spring force acting under the piston. By pressurizing the upper control connection, the valve is closed by the control pressure acting on the piston.
7.1.3 Control function I (CFI)
The device operates without spring force. Here, the piston is pressurized alternately, namely at the lower control connection for opening and at the upper one for closing the valve.
7.1.4 Flow below the seat
Depending on the version, the valve is closed against the medium flow by spring force (control function A, CFA) or by control pressure (control function B, CFB).
As the medium pressure is under the swivel plate, this pressure contributes to the opening of the valve
CFA/CFI CFB/CFI
Figure 5: Flow below the seat (closing against medium)

english
Type 2000, 2002, 2012
Conversion of control function
7.1.5 Flow above the seat
The valve is closed by spring force (control function A, CFA) with the medium flow. As the medium pressure is over the swivel plate, it supports the closing process of the valve and also contributes to the sealing of the valve seat.
The valve is opened by the control pressure.
