Scored Sanitary Reverse Acting Disc (SSR)

  • Hygienic Overpressure Protection

What is a Scored Sanitary Reverse Acting Disc?


The Scored Sanitary Reverse Acting Disc (SSR) is a precision-engineered rupture disc designed to reverse and burst at a predetermined pressure, providing rapid and reliable overpressure protection. These discs are specially scored to ensure a clean, consistent break, minimizing fragmentation and maintaining hygienic integrity in sensitive systems.

Welcome to Ventil Components, a leading manufacturer and supplier of high-performance sanitary rupture discs. Our Scored Sanitary Reverse Acting Discs (SSR) are specifically engineered for applications requiring hygienic pressure relief. These discs ensure optimal safety, reliability, and compliance with stringent sanitary standards.
