Danfoss 088H3114 TWA-A Thermal Wax Actuator 24V NC with End Switch

The Danfoss 088H3114 is a TWA-A series thermal wax actuator designed for use with electrical on/off controls to activate Danfoss valves and hydronic floor heating manifolds. This 24V AC actuator operates in a normally closed (NC) position and features an integrated end switch for system feedback and control verification.

Key Features:

• 24V AC/DC operation (±15%), 2W power consumption for energy-efficient performance
• Thermo-hydraulic wax element technology gradually opens or closes valves to eliminate water hammer
• Visual position indicator clearly displays open or closed valve status
• Integrated end switch (NC/S configuration) provides electrical feedback for system monitoring
• 110N closing force ensures reliable valve operation
• Approximately 3-minute stroke time for smooth, silent operation
• 950mm (37.4 inch) cable length for flexible installation
• IP41 enclosure rating protects against dust and water ingress

Applications:

• Hot water radiator, baseboard, and fin tube heating systems
• Hydronic floor heating zone controls
• Hot water service systems
• Hot/chilled water applications for air handlers

Compatible with Danfoss RA2000, RA-C, RAVL, and RAV radiator valves, as well as floor heating manifolds. Can also be used with Danfoss RET-B, RET-24, and FH-WS low voltage thermostats. Operates reliably in ambient temperatures from 2°C to 60°C (36°F to 140°F).
