Electrothermal heads
Electrothermal heads are control components used in heating systems to regulate the flow of hot water through radiator valves and distributors. These heads respond to electrical signals to open or close the valve position, enabling precise temperature control. The category includes models compatible with a range of valve types, including IVAR.CS 553, CI 557, UNIMIX, KS IVAR, MULTIMIX-C, and BS EQUIMETER. They are available in different voltage options, including 12V, 24V, 230V, and 0–10V configurations, and offer either normally closed (NC) or normally open (NO) operation modes.
How to choose
- Select the correct voltage rating (12V, 24V, 230V, or 0–10V) based on the control system and power supply available.
- Ensure compatibility with the valve or distributor type, such as IVAR.CS 553 or CI 557, to guarantee proper function.
- Check the operating mode (normally closed or normally open) to match the system’s control logic and safety requirements.
- Confirm the connection size is M30 x 1.5, which is standard for most radiator valves in this category.
Frequently asked questions
Can electrothermal heads be used with dynamic balancing valves?
Yes, specific models are designed for use with dynamic balancing valves, including 230V and 24V variants.
What is the difference between normally closed and normally open operation?
Normally closed (NC) heads remain closed when no power is applied and open when powered. Normally open (NO) heads behave in the opposite way.
