Premier Reverse-Acting Hygienic Rupture Disc

Specifically designed to meet stringent hygienic requirements and be cleaned through CIP (clean-in-place) and SIP (steam-in-place) methods without removal. This 3-A compliant rupture disc includes:

  • 95 percent operating ratios.
  • Superior cycling capabilities from zero to full pressure or full vacuum.
  • Fast lead times, a result of Fike's global manufacturing capabilities.
  • Optional electro-polished surface finish and passivation.

Protecting Against Product Contamination

An impure product batch can have disastrous effects on its users and the business. Learn how pressure relief valves may contribute to product contamination, and how rupture discs are used to solve this problem.


What Is A “Hygienic” Rupture Disc?

Hygienic rupture discs must maintain similar hygienic qualities found throughout a production facility in the biotech, food and beverage and pharmaceutical industries. Non-hygienic rupture discs and holders may collect unwanted media or bacteria, resulting in ruined batches, production downtime and irreparable harm to customer confidence.

1. CIP (Clean-in-Place)/SIP (Steam-in-Place) Compatible

The rupture disc remains during cleaning and is engineered to withstand high burst pressures and temperatures produced by CIP/SIP equipment.

2. Option For Electro-Polishing

A method of using a mild acid and low voltage of electricity to create an ultra-smooth finish, which greatly reduces areas for media or bacteria to collect.

3. Option For Passivation

A method that removes any microscopic traces of carbon (which may cause rust or corrosion) during the rupture disc’s production.

4. Non-Contaminated Packaging

Quality control hygienic packaging ensures contaminants do not transfer onto rupture discs.

5. Disc Materials

Material used is often stainless steel or hastelloy to match the material of the rest of the facility.
