Hattersley 950W PN16 Butterfly Valve - Lever Operated

The FSSCRS Sanitary Rupture Discs are compression-loaded or reverse-acting discs with micro-scored, petal-shaped sections, featuring 4, 6, or more radial scores for reliable opening. Designed to meet 3-A SSI standards for hygienic equipment, they are ideal for Pharmaceutical, Food, and Biotechnology industries. Constructed from AISI 316L stainless steel (other alloys available), their smooth process-side surface supports C.I.P. and S.I.P. treatments to maintain aseptic conditions. PTFE gaskets (FDA, USP Class VI, 3-A, EU 10/2011 compliant) enable installation in Clamp fittings. Suitable for gas or liquids with a gas cushion, including cycling and pulsating conditions, these discs open fully in milliseconds without fragmentation and can withstand absolute vacuum conditions without supports. Optional PTFE coating adds extra protection.

The FSSUMSU Sealed Unit Rupture Discs feature a convenient threaded connector and comprise two parts that house a calibrated rupture disc. This rupture disc is meticulously inserted into a threaded and sealed container, making it easy to mount small discs within plants. Designed for reliability, these units simplify handling, eliminating the need for specialised personnel. FSSUMSU sealed units are adept at managing both gases and liquids, even in cyclical and pulsating conditions. They respond to over-pressure in mere milliseconds, offering essential protection for plants, plant equipment, and containers.
