The best choice for applications involving highly oxidizing agents and halogens
Disks extend corrosion resistance by utilizing a liner on the flat surface of the disk that contacts the process media
Disks are capable of resisting virtually any corrosive except elemental free fluorine
Sizes 1/2” (13 mm) thru 24” (610 mm) diameters
Designed to fit industry standard flanges ASME B16.5, ISO and JIS
Burst ratings 0.50 psig (0.03 barg) to 1000 psig (68.95 barg) or higher
0% manufacturing range
Operating pressures to 90% of the disk’s marked burst pressure. Contact ZOOK for operating ratio for burst pressures below 40 psig (2.76 barg)
