It is an absolute "classic” in our range. For over 40 years, we have been producing this simple, but incredibly strong cast-iron valve for use as a dust valve under filters and cyclones and as a low pressure rotary valve (max. 0.05 bar, max. 0.1 bar for 8-blade rotors and the HT450). The options and possibilities available in our HT range for finding the perfect valve for your application are virtually endless. The HT250/350 is also interchangeable with the HT250S/350S.
