Sanitary Fitting Specifications

ASME BPE and DIN 32676 Series C are the leading standards for sanitary fittings to which GCR-SW rupture disk assemblies are installed. Alternative GCR-SW options are available upon request to support installation to DIN 32676 Series A and Series B fittings. Please identify the required fitting standard at time of inquiry and order.

Burst Tolerance

Marked Burst Pressure Burst Tolerance
≤ 40 psig (2.76 barg) ± 2 psig (0.138 barg)
> 40 psig (2.76 barg) ± 5%

Saf-T-Change Quick Disk Replacement (QDR)
Saf-T-Change Quick Disk Replacement (QDR)

After activation, the replacement disk is quickly slid into place. Saving hours of lost production due to blown rupture disks.

Tell-Tale Assemblies
Tell-Tale Assemblies & Excess Flow Valves/Gauges

A gauge tap in the outlet flange of the safety head may be considered when the safety head is installed in a vertical position.

Spare Safety Heads & Cap Screws

Jackscrews
Jackscrews

When activated, the jackscrews effectively separate the flanges, providing adequate clearance to remove or insert a safety head and external gaskets.

Lifting Lug Eye Bolts
Lifting Lug Eye Bolts

Eye bolts are recommended when weight and/or accessibility is a factor in lifting safety heads.

Baffle Plate
Baffle Plate

When a safety head is free-vented to atmosphere, a baffle plate may be considered to disperse overpressure and absorb recoil.

GCR-SW Advantages

  • Simple: Leak tight, welded, single piece assembly.
  • Protective Design: Disk fully contained inside the assembly, protecting it from damage during installation and handling.
  • Versatile: Ideal for horizontal, vertical, and oblique installation where standard sanitary disks with separate fittings are difficult to remove and install.
  • Long shelf life: No elastomer gaskets present in the assembly.
  • Robust: Single piece assembly design significantly isolates the rupture disk from misaligned or unsupported piping.
  • Torque Resistant: Single piece assembly design significantly isolates the rupture disk from the effects of excessive torque.
  • Reusable: Typically, GCR-SW assemblies can be removed from service, carefully cleaned, and reinstalled.
  • CIP/SIP Advantage: Benefiting from the single piece assembly design, there are no elastomer components to degrade in the assembly.
  • Less Inventory: Common burst pressure requirements can be supported with one inventory item [no integral gasket.
