Nabic 568 Anti Vacuum Valve
 

Fig 568 Anti-Vacuum Valves are used to protect drying cylinders, calorifiers and tankers from collapse due to internal vacuum. They are also used on steam systems, to assist condensate drainage and to prevent suction of contents from vats. Vacuum valves are normally fitted vertically, at the top of the vessel or pipeline being protected. Horizontal revolving cylinders however should have a Fig 568 fitted at each end, diametrically opposite one another. NABIC Valves now come with an Industry leading 5 Year Guarantee.
