Danfoss 082F-1110 24V Electric Thermal Actuator Normally Closed with End Switch

The Danfoss 082F-1110 is an ABRA-A5 electric thermal actuator specifically designed for use with Danfoss RA2000, RA-C, and RA15/6 series valves in hot water heating and cooling applications. This normally closed (NC) actuator features an integrated end switch for system control and feedback.

Key Features:

• 24V AC/DC power supply with +20%/-10% voltage tolerance
• Low 1W power consumption for energy efficiency
• Heated wax element with PTC resistor for gradual valve actuation
• 4mm actuator travel with 22.5 lbf (100N) linear force
• Approximately 4-minute opening and closing time to eliminate water hammer
• Integrated end switch that closes when actuator reaches 50% open position
• Visual position indicator for easy status monitoring
• Quick-mount design for easy installation and removal from valve
• Compact, low-maintenance construction

The slow actuation of this thermal actuator makes it ideal for applications where gradual valve operation is desirable to prevent water hammering. Suitable applications include radiator systems, baseboard and fin tube heating, hydronic floor heating, hot water service systems, hot/chilled water for air handlers, and low-pressure steam systems. Operating temperature range: 32°F to 212°F (0°C to 100°C) fluid temperature, with ambient temperature range of 32°F to 140°F (0°C to 60°C).
