Holders
Full line of Advanced New Pre-Torque Holder Designs Together with
Industry-Leading Quality Flat and Angle Seat Insert, Union & Screw Type Holders
Holders are a synergistic partner of the rupture disk. Typically, they consist of a machined base (inlet) flange and a holddown (outlet) flange in which the rupture disk is seated in place. This tight, metal-on-metal seal allows the rupture disk to perform its designed function. Various holder designs are available, including pre-torqued, insert, double disk, screw type, and sanitary ferrule quick releases.
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
