Explosion-proof valve CARZ

The CARZ explosion-arresting check valve is your protection in explosive dust removal systems.

Description

The CARZ explosion-arresting check valve can prevent the propagation of a dangerous explosion and flame wave toward the work area. Using our CARZ, you reduce the risk of explosion spread to people and equipment.

Job Description

During normal operation, the valve plate is open at a wide angle, ensuring low pressure loss. In the event of an explosion in the filter, a pressure wave will close the valve plate and lock it in place. When closed, the plate creates an effective barrier against the approaching flame front. This prevents the explosion from moving toward the work area. We can provide complete protection against dust explosions in any production environment, for any type of dust, using a filter system and an explosion-arresting valve.
