Thermostatic Biomass Valve

Biomass Boilers - BVTS Thermostatic Valve

The Thermostatic Valve BVTS is designed for protection of boilers and fire stoves. It prevents overheating by discharging water from heat generator, condensing coil or heat exchanger.

The BVTS valve is used also to prevent backburning in the fuel store of biomass boilers by flooding the fuel in case of excessive temperature.

The BVTS biomass valve is self-acting, meaning it operates without supply of auxiliary energy such as electricity or compressed air. 
\Compressed Air Controls

Controlling Compressed Air

Danfoss supplies its entire product controls line to the compressed air market.

From switches to motor control gear to thermostatically operated valves, Danfoss is a pioneer in creating pressure, temperature and fluid controls for the air industry.
