Piston valve: Danfoss LLC, Industrial Automation

Sponsored by

Danfoss recently redesigned its EV245B servo-operated valve for steam applications. With a longer stroke, the piston valve is suited for a range of clean steam applications as it can heat the medium faster - making it ideal for applications where rapid heating is critical. To enhance versatility, a series of three different compact polymer coil types that simply clip on to the valve were released in January 2012. Covering three temperature ranges, the BB dc coil is ideal for temperatures up to 140°C, while the BB ac and BN dc coil is suitable for temperatures up to 160°C, and the high temperature BQ ac coil can cope with temperatures up to 185°C.
