Push Button Drain Valve

The CONCOA 432 Series six-port, dual-stage cylinder regulator provides stable pressure control for toxic, non-corrosive, and ultra-high purity gases in laboratory and industrial settings. Dual-stage design minimizes pressure fluctuations from cylinder depletion. Features include metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, cleanroom assembly, helium leak-checked integrity, pipe-away relief, and captured vent bonnet. Constructed from 316L stainless steel body with chrome-plated brass bonnet, PCTFE/PTFE seats, 10-micron stainless steel filter, Cv 0.1, 1/4 in FNPT ports, and 2 in gauges. Rated up to 3000 PSIG (3500 or 4500 PSIG optional), temperature range -40°F to 140°F (-40°C to 60°C). Conforms to CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, and CRN OH5216.

Introducing the Valpres 76 Series Split Body Two-Piece Full Bore Ball Valve, designed for exceptional performance and reliability in demanding applications. This valve features a robust stainless steel ball and stem, complemented by PTFE seats and a combination of PTFE, Graphoil, and FKM seals. With its antistatic and fire-safe properties conforming to BS6755 Part 2, API Specification 6FA, and ISO 10497, this valve is suitable for a wide range of industrial uses. Additionally, it carries ATEX II 2GD T3 approval, ensuring it meets stringent safety standards. The end connections are flanged and drilled according to several options, and it is lever operated for ease of use.

The FSLPDDW Double Way Rupture Discs are sophisticated composite conventional discs constructed from four key components: a slotted, perforated metal section, a sealing membrane (typically made from PTFE, but also available in various metallic and non-metallic materials), a protective section, and a calibration ring. Designed to be installed between flanges, these discs are ideal for use with gases and liquids in static conditions, particularly at low pressures. The FSDIFDW discs promptly react to excessive pressure, achieving complete opening within milliseconds, making them an excellent choice for valve protection. Vacuum or counter-pressure support options are also available. Additionally, composite rupture discs offer simultaneous protection from both pressure and vacuum.
