## Summary description

Danfoss thermostatic actuator model 088H3220 is a normally closed (NC) 230V electric actuator designed for controlling radiator valves and similar heating system valves. It provides reliable on/off control of valve position, compatible with typical Danfoss valve fittings. Intended for residential and light-commercial heating installations to automate temperature regulation and improve system responsiveness.

## Long description

Danfoss thermostatic actuator 088H3220 NC 230V is an electric actuator designed for on/off control of radiator valves and similar heating system valves. The actuator operates as normally closed (NC), supplying reliable movement to open valves when power is applied and returning to closed position when power is removed. It is compatible with common Danfoss valve fittings and intended for use in residential and light-commercial heating installations where automated valve control is required for temperature regulation and improved system responsiveness.
Advantages
The actuator offers straightforward installation and electrical connection for integration into existing radiator valve assemblies. Its normally closed design ensures fail-safe behavior by defaulting valves to the closed position without power. The 230V supply makes it suitable for standard mains-powered systems while maintaining compact dimensions that do not interfere with radiator placement. Constructed to meet typical heating-system durability expectations, it provides consistent on/off actuation for automated temperature control.
Suitable for
Automated control of radiator valves in residential heating systems
Light-commercial heating installations requiring on/off valve actuation
Retrofitting manual radiator valves to timed or thermostatic control
Integration with building management or room thermostats that use 230V actuator outputs
Key specifications
Actuation type: normally closed (NC), on/off operation
Supply voltage: 230 V AC
Intended application: radiator and hydronic valve control
Compatibility: designed for use with Danfoss valve fittings and similar valve bodies
Operating environment: indoor heating systems (residential and light-commercial)
Action: electric linear actuation for valve stem movement
How to use
Mount the actuator onto a compatible radiator or hydronic valve according to the valve manufacturer’s mounting instructions, ensuring correct alignment and secure attachment. Connect the actuator to a 230V mains supply and to the control output of a thermostat or control system that provides on/off switching. When the control circuit supplies power, the actuator opens the valve; when power is removed, the actuator returns the valve to its closed position. Verify mechanical movement and electrical connections before full operation and follow local electrical safety regulations during installation.
Usage recommendations
For reliable operation, use the actuator in dry indoor environments and avoid exposure to direct moisture or corrosive agents. Confirm compatibility with your valve body and control system prior to installation. Regularly inspect mounting and electrical connections during scheduled maintenance and isolate power before servicing.
