Hattersley 950G PN16 Butterfly Valve - Gearbox Operated

The CONCOA 312 Series is a five-port, chrome-plated brass barstock, dual-stage cylinder regulator designed for high-purity inert gas applications. It provides primary pressure control for non-corrosive, high-purity (up to grade 5.5) or liquefied gases. Its two-stage design reduces pressure fluctuations caused by supply cylinder depletion, making it ideal for applications requiring stable delivery pressure. Configurable at the factory, it can serve as a single-station manifold with options such as purge, low-pressure alarm, or multiple inlets.

The FSDCDS Sanitary Rupture Discs are designed for aseptic applications, consisting of a slotted, perforated metal section, a seal membrane (commonly PTFE, with other materials available), and a protective layer. Ideal for use with gas or liquids under static or low-pressure conditions, these discs open fully within milliseconds during overpressure events, without fragmentation. They can be fitted with supports for vacuum and counter-pressure protection, allowing simultaneous protection against both. PTFE gaskets certified to FDA, USP Class VI, 3-A, and EU 10/2011 standards make installation in Clamp fittings (sanitary, Tri-Clamp, Tank Connection) simple. The FSDCDS is also suitable for C.O.P. (Clean-Out-Of-Place) applications.
