Blast valves
Blast valves are mainly used in oil & gas, nuclear power plants and other industries where explosions could happen. KC blast valves could be installed in inlets and outlets of ventilation in the facilities. And also can be installed on all types of wall blast surfaces, either vertically or horizontally on the roof. They are flexible in all ranges of airflow and pressure drop, with blast protection of 23 bar and duration of 5ms. Instant closing time only 1.1ms. They are designed to meet different situations of explosion in high quality
