| Danfoss Bio-mass valves for fuel of the future
With the rising energy prices and the high environmental concern, bio-mass is the fuel of the future. The Danfoss BVTS thermostatic valve offers reliable, safe and maintenance free operation, making bio-mass boilers the optimum choice for environmentally friendly heating of e.g. residential housing, industry and commercial buildings. The BVTS thermostatic valve offers the ultimate protection for bio-mass or solid fuel boiler systems. Based on more than 75 years of experience, these unique valves protect against overheating and back burning. Offering safe, reliable and maintenance-free operation, the BVTS valves feature:  • Optimum tightness even after activation • Easy installation • Self-acting technology • Pre-set to open at 95° C • Superior quality • Competitive solution
Overheating protection The Danfoss bio-mass valves prevent water in bio-mass boilers from reaching boiling point. If the water temperature rises, the valve will open and allow cold water through the heat exchanger system to quickly and efficiently lower the temperature in the boiler.
Back-burning protection The Danfoss bio-mass valves prevent back burning by monitoring the temperature in the fuel feed system. If the temperature in the fuel feed system rises above 95º C, the valve will open and dispense enough water to extinguish any fire. After activation the valve will close and remain tight, minimising the need for subsequent cleaning and maintenance.
Self-acting principle requiring no external power The Danfoss BVTS thermostatic valve will operate safely regardless of the ambient temperature, and the self-acting technology means that the valve does not require electricity or other forms of energy in order to work.
