NABIC 568 Anti-Vacuum Valves are essential for safeguarding drying cylinders, calorifiers, and tankers against collapse caused by internal vacuum conditions. These valves are equally valuable in steam systems, where they facilitate effective condensate drainage and prevent the unwanted suction of contents from vats. Typically, vacuum valves are installed vertically at the top of the vessel or pipeline they protect. In the case of horizontal revolving cylinders, a NABIC 568 valve should be fitted at each end, positioned directly opposite each other. Our NABIC Valves are backed by an industry-leading 5-Year Guarantee for your peace of mind.
