NABIC 520 High Lift Double Spring Safety Valve

The CONCOA 401 Series six-port, chrome-plated brass barstock regulator provides single-stage primary pressure control for ultra-high purity inert, non-corrosive, or liquefied gases (up to grade 5.5). Ideal for applications tolerating minor outlet fluctuations or with constant/low inlet pressure (<500 PSIG/34 BAR), it is front-panel mountable and configurable with purge, low-pressure alarm, or multiple inlets. Key features include metal-to-metal diaphragm seal, CAPSULE® seat with 360° filtration, pipe-away relief valve, cleanroom assembly, captured vent bonnet, and helium leak-checked integrity. Specifications: max inlet 3000 PSIG (210 BAR) standard; body and bonnet chrome-plated brass; PTFE/PCTFE seats; 10 µm sintered bronze filter; 316L diaphragm; Cv 0.1; 1/4 in FNPT ports; 2 in gauges; temperature -40°F to 140°F (-40°C to 60°C). Conforms to CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, CRN OH5216.

The AURA EX2 regulator is meticulously crafted to provide precise and consistent primary pressure control for gases or liquids, accommodating inlet pressures of up to 6000 psig. Unlike standard regulators, the EX2 is specifically designed for applications where even slight fluctuations in outlet pressure due to diminishing inlet pressures are intolerable. At the heart of the EX2 lies AURA’s innovative dual encapsulated seat design, which merges multiple moving internal components into a single comprehensive unit. This advancement minimises maintenance needs, eliminates common failure points, and enhances long-term reliability. Each encapsulated seat is protected by a 10-micron, 360° filter, ensuring superior particle filtration compared to conventional pressed-in disks. Unlike typical regulators that filter solely through the pipeline port, the EX2 safeguards against harmful particles from all inlet ports. A diverse selection of seat materials and orifice sizes guarantees optimal performance across a range of demanding applications. AURA’s precision machining process provides metal-to-metal seals that ensure the highest level of leak integrity while achieving ultra-smooth surface finishes of 4–25 Ra to minimise corrosion. The regulator’s compact internal volume also cuts purge gas consumption, resulting in improved operational efficiency. Every EX2 is assembled within a Class 100 cleanroom, inclusive of all gauges, fittings, and valves. Each unit undergoes thorough cleaning for oxygen service, is subjected to 100% helium leak testing, and passes multiple flow and function tests, ensuring unparalleled purity, durability, and reliability. For environments that are highly corrosive, the EX2 is available with Dursan® LS inert coating technology, offering exceptional resistance to acidic and caustic media, frequently outperforming exotic alloys. This makes the EX2 a dependable choice for critical applications.
