Engineering notes

Conduct the electrical connections in accordance with local regulations on electrical

installations as well as the internal or connection diagrams.

Safety regulations and restrictions designed to ensure the safety of people and

property must be observed at all times!

For media below 0 °C the ASZ6.5 or ASZ6.6 stem

heater is required to keep the valve from freezing. For

safety reasons the stem heater is designed for an

operating voltage of AC 24 V / 30 W.

For this case, do not insulate the actuator bracket and

the valve stem, as air circulation must be ensured. Do

not touch the hot parts without prior protective

measures to avoid burns.

Non-observance of the above may result in accidents

and fires!

Recommendation: Above 140 °C insulating the

valves is strictly recommended.

Observe admissible temperatures, refer to «Use» on page 1 and «Technical data» on

page 11.

If an auxiliary switch is required, its switching point should be indicated on the plant

schematic.

Every actuator must be driven by a dedicated controller (refer to

«Connection diagrams», page 14).
