Broady 3600 Balanced Safety Relief Valve

The FSY90S Sanitary Rupture Disc is a compression-loaded, reverse-acting disc with precision scoring around its circumference, engineered to meet the stringent hygiene standards of 3-A SSI for public health protection. Designed for use in the pharmaceutical, food, and biotechnology sectors, it is manufactured as standard from AISI 316L stainless steel, with alternative alloys available on request.

A smooth process-side surface makes the disc ideal for CIP and SIP cleaning processes, helping maintain aseptic conditions. Installation is simplified using PTFE gaskets certified to FDA, USP Class VI, 3-A, and EU 10/2011 standards, enabling secure fitment in sanitary clamp connections such as Tri-Clamp and Tank Connection fittings.

The FSY90S is suitable for use with gases or liquids (with a gas cushion) and performs reliably under cycling and pulsating conditions without compromising safety. On reversal, the disc opens fully within milliseconds along the scored line, ensuring clean, fragment-free rupture and dependable pressure relief.

Important Note: The DN value embossed on the valve body indicates the NABIC 500 body size utilised in the manufacturing of this valve and does not correlate with the inlet or outlet size. For instance, a valve with 1" connections (DN25) is constructed using a DN20 NABIC 500 valve body, and thus, the DN20 will be marked on the side of the valve.
