The Fike CV-S and CV-S-HV explosion vents have a pre-bulged composite construction. They’re use in applications where the operating pressures approach the burst pressure and where moderate to high vacuum pressure or cycling conditions may exist. Standard applications include separation, drying, preservation, transport, and processing operations.
