Hattersley Fig 3047W PN25 Swing Check Valve

The CONCOA 428 Series three-port, stainless steel barstock regulator delivers single-stage secondary pressure control for ultra-high purity gases or point-of-use applications requiring face seal connections. It is front and rear panel mountable and supports flexible system configurations. Key features include metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, butt-welded face seal connections for superior leak integrity, cleanroom assembly, helium leak-checked integrity, and a captured vent bonnet. Constructed from 316L stainless steel body, chrome-plated brass bonnet, PTFE seats and internal seals, 10-micron 316 stainless steel filter, Cv 0.1, 1/4 in face seal ports, 2 in gauge. Max inlet pressure 3000 PSIG (210 BAR), temperature range -40°F to 140°F (-40°C to 60°C). Complies with CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, and CRN OH5216.

Double oil filters, also known as duplex oil filters, are specialised filtration units designed for use in industrial refrigeration systems, particularly those employing ammonia (NH₃) or CO₂. They continuously eliminate impurities from the compressor oil while ensuring uninterrupted operation during filter maintenance or replacement.

A double oil filter features two parallel filter housings linked by a changeover valve or a three-way valve. This innovative setup enables the system to alternate between filters without the need to shut down the refrigeration system, ensuring optimal efficiency.

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.
