TL-39 thermal actuator is a normally-closed electric actuator for underfloor heating manifolds,designed to control water flow via room thermostats. Featuring M30×1.5 interface, silent operation,IP54 protection and quick snap-on installation.
Description
TL-39 thermal actuator is designed for water radiant floor heating systems.
It provides reliable on/off control for heating manifolds and zone valves,
featuring a normally-closed configuration, silent operation, and quick snap-on installation.
Product Description
The TL-39 thermal actuator is a two-point on/off electric actuator tested by TUV,
widely used to control water flow in underfloor heating systems, radiators, and heating manifolds.
It automatically opens or closes the valve according to signals from room thermostats or other electrical switches.
With a wax-filled element and normally-closed (NC) design, the TL-39 ensures stable, safe,
and energy-efficient operation. Its quick-lock snap action allows tool-free installation,
making it ideal for residential and commercial floor heating applications.
