Sanitary Reverse Buckling Disks BSBSystems.com | BSB.ie Visit our website for the most complete, up-to-date information GCR-NTM and NovAseptic® NA-Connect Disk Holder The GCR-N and GCR-NS™ reverse buckling disks are installed in NovAseptic® NA-Connect holders, which permit flush mounting of the disk with the interior wall of the vessel and are easy to clean and sterilize. The GCR-N design uses Saf™ technology offering a wide range of burst pressures for sanitary / aseptic applications in the pharmaceutical, biotechnology and food industries. Liners are available in all sizes as optional on the process side of the disk. FEP or PFA are generally used. Temperature range FEP -40°F to 400°F (-40°C to 204°C) PFA -40°F to 500°F (-40°C to 260°C) Size Minimum burst pressure for lined disks at 72°F (22°C) • One disk design for gas and liquid service • Flush mounting with vessel wall • Fail-safe design: damage safety ratio < 1 • Low to high burst pressures • Ideal for CIP / SIP service* • Installed with integral sanitary /aseptic gaskets • 8-16 micro-inch typical disk surface finish • Minimum dead space between process fluid and the disk • Suitable for operating pressures up to 90% of marked burst pressure** or 95% of the specified minimum burst pressure (CEN standard pending) • Designed for non-fragmentation • Standard manufacturing design range, 0%, optional -5%, -10% • Withstands full vacuum at all burst pressures • SAS™ (sanitary alert sensor) with leak sensing option available • Integral burst disk sensor option • Worldwide patents pending *Clean / steam in place **At marked burst pressures of 40 psig (2.76barg) and below, the recommended maximum operating pressure is 90% of the marked burst pressure, less 2 psig (0.138barg) tolerance GCR-N Disk Specification Minimum / maximum burst pressure at 72°F (22°C) psig (barg) Burst pressure Nominal disk size Inlet height NAconnect holder type NA-connect design pressure is 101 psig (7barg) at 302°F (150°C) Other burst pressures may be available; Consult BS&B NA-Connect® is a registered trademark of NovAseptic Equipment AB NovAseptic is a registered trademark of Millipore Corporation.
