ZK 313 ASME
Operation
Attention
■
As the stuffing box screw is tightened, the break-away force and the friction force of
the valve spindle are increased.
■
The break-away force and the friction force of the valve spindle must not exceed the
maximum operating force of the actuator.
■
Excessive tightening of the stuffing box screw impairs the function of the actuator and
may cause blocking of the valve spindle.
If the valve spindle is blocked, the valve can no longer open, regulate or close.
Decommissioning
Danger
Risk of severe burns and scalding over the entire body!
Before loosening flanged connections, stuffing box connections or sealing plugs make
sure that all connected lines are depressurised (0 bar) and cooled down to room
temperature (20 °C).
Deinstall the valve and separate the waste materials in accordance with the specifications of the table
“Materials” on page 8.
Observe national legal regulations regarding waste disposal.
Disposal
Please contact the manufacturer or your local dealer if maintenance is required.
