Holders

ZOOK revolutionized the rupture disk holder market with the introduction of the FAH and RAH Series of next generation pre-torque holders. Each holder is designed to fit multiple types of ZOOK Forward Acting (FAC, FAX) and ZOOK Reverse Acting (RA4, RA6, RA8, RAX) disks.

The ZOOK Pre-torque design conveys certain advantages:

• Pre-assembly of a rupture disk into a holder prior to field installation
• Removal of the assembly from the piping system for inspection without disturbing the seal integrity of the rupture disk
• Pre-torque bolts properly seat the disk by engaging the holder bite

Other notable features of the FAH/RAH Holders include:

• Locating Pin allows only correct type disks to be mounted into holder
• Flow direction arrows on disk tag and holder provides permanent visual verification that holder assembly is properly oriented in the piping system
• Fluoropolymer coated socket head cap screws resists corroding to holder assembly and provides easy removal without special sockets
• Polyethylene cap screw covers prevents debris from building up in cap screw head
