Pressure and Vacuum Relief Valves for Cryogenic Storage Tanks Decades of experience in manufacturing pilot-operated pressure/vacuum relief valves, our expertise in computer-optimized design, and our extensive test facilities form the basis for the development of

Working principle of Flame Arresters Flame Arresters (or ‘flame arrestors’) are designed to allow the flow of gases, liquids, etc. and to prevent flame transmission. PROTEGO® Flame Arresters are composed of individual FLAMEFILTER® (flame arrester discs),

Diaphragm Valves PROTEGO® Diaphragm Valves function as pressure vacuum relief valves. The flexible diaphragm allows them to work as a dynamic flame arrester which provides endurance burning protection. For additional safety, these devices are equipped with a
