CONCOA 212 Series Regulator
The CONCOA 212 Series is a five-port, chrome-plated forged brass, dual-stage cylinder regulator designed for primary pressure control of high-purity, non-corrosive, or liquefied inert gases (up to grade 4.5). Its dual-stage design ensures stable pressure and delivery regardless of supply pressure variations. Factory-configurable options include single-station manifolds, purge, low-pressure alarms, or multiple inlets.

FSGGMG - Graphite Rupture Discs FSGGMG - Graphite Rupture Discs
The monoblock FSGGMG Graphite Rupture Discs are highly versatile and designed for a wide range of applications, easily positioned between flanges. These graphite rupture discs offer exceptional resistance to aggressive fluids and exhibit low sensitivity to temperature variations at varying bursting pressures. Manufactured from ultra-pure graphite and impregnated with phenolic resins, these discs ensure impermeability. Upon rupture, they provide a complete opening with fragmentation. For rupture pressures under 1.7 barg, vacuum support is required, while discs remain self-supporting at higher calibrations.
