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 theinstallation personnel.

High pressure danger!
▶ Before loosening lines or valves, switch off the pressure and bleed the lines.
Danger from electrical voltage.
▶ Before reaching into the device or the system, switch off the power supply and secure it against
reactivation.
▶ Observe the applicable accident prevention and safety regulations for electrical devices!
Risk of burns/fire due to hot device surface if device operated continuously.
▶ Keep the device away from highly flammable substances and media and do not touch with bare hands.
General hazardous situations.
▶ Ensure that the system cannot be activated unintentionally.
▶ Make sure only trained technicians carry out installation and maintenance work.
▶ After an interruption in the power or pneumatic supply, ensure that the process is restarted in a definedor controlled manner.

CONVERTING CONTROL FUNCTION

9.1

Description of control functions

Depending on the variant, the seat of the valve is closed with or against the medium flow. Spring force (SFA) or
pneumatic pilot pressure (SFB and SFI) generate the closing force on the swivel plate. The force is transmitted
via a spindle connected to the actuator piston.
Exact descriptions of the control functions can be found in the Type 2000 operating instructions
at: www.country.burkert.com

9.1.1

Control function A (CFA)

In the rest position, the valve is closed by spring force. By pressurising the lower control port, the seal islifted from the valve seat and the flow is released. The open state is indicated by a position indicator locatedin the cover of the actuator.

9.1.2

Control function B (CFB)In the depressurised state, the valve is opened by the spring force acting under the piston. When the upper
control port is pressurised, the valve is closed by the pilot pressure acting on the piston.

9.1.3

Control function I (CFI)

The device works without spring force. The piston is alternatingly pressurised, namely at the lower pilot air
port for opening and the upper for closing the valve.

9.1.4

Flow direction below seat

Depending on the variant, the valve is closed against the medium flow either with spring force (control
function A, CFA) or pilot pressure (control function B, CFB).
As the medium is present under the swivel plate, the medium pressure contributes to the opening of the valve.

9.1.5

Flow above seat

The valve is closed by spring force (control function A, SFA) with the medium flow. As the medium pressure
is applied over the swivel plate, it supports the closing process of the valve and additionally contributes tosealing the valve seat.
The valve opens through pilot pressure.

Conversion from control function A (CFA) to B (CFB)DANGER!

Danger from high pressure!
▶ Before loosening lines or valves, switch off the pressure and bleed the lines.
Risk of injury due to improper maintenance work!
▶ Maintenance may be carried out by authorised technicians only!
▶ Use an open-end wrench, never a pipe wrench, to screw the valve body or actuator in or out.
▶ Observe tightening torques.
