Self-Operated Temperature Control Valve for Floor Heating

Product Summary

This self-operated thermostatic valve is designed for floor heating systems, offering precise temperature control without any external power source. The liquid-filled bulb actuator responds to temperature changes, directly modulating flow to maintain comfortable and consistent heat distribution.

Temperature Range: 20–80°C
Size: DN15–DN32
Working Pressure: ≤1.0MPa
Accuracy: ±1°C
Material: Brass

Key Selling Points

Zero Energy Operation: No power, no controller, no wiring – saves installation cost and works during power outages.
High Accuracy ±1°C: Liquid-filled bulb sensing provides precise temperature control compared to wax actuators (±3°C).
Wide Temperature Range 20-80°C: Suitable for underfloor (30-50°C), radiator (50-80°C), and solar heating applications.
Maintenance-Free Design: No motor, no PCB, no battery – reduces failure points and maintenance needs.
Customizable Capillary Length: Standard 1m, max 5m, flexible installation of remote bulb.
