Hattersley Fig 1000L PN20 Metering Station - Low Flow

The CONCOA 325 Series is a chrome-plated brass, single-stage regulator designed for lecture bottle applications. It provides reliable pressure regulation for non-corrosive gases, using the compact CAPSULE® seat design to maintain excellent control across the lecture bottle’s pressure range.

Features:

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat with 360° integral filtration

• Low wetted surface area reduces purge requirements

• Helium leak-tested for integrity

• Minimal droop ensures stable outlet pressure as gas is depleted

Specifications:

• Max inlet pressure: 3000 PSIG (210 BAR)

• Body: Chrome-plated brass barstock; Bonnet: Chrome-plated die-cast zinc

• Gauges: 1½" (38 mm) plated case

• Seat: PTFE; Filter: 10-micron sintered bronze

• Temperature range: -40°F to 140°F (-40°C to 60°C)

• Diaphragm: 316L stainless steel; Cv: 0.02

• Helium leak rate: 1 × 10⁻⁸ scc/sec

• Internal seals: PTFE; Ports: 1/8" FNPT (inlet, outlet, gauges), 1/4" FNPT (relief)

• Compliance: Meets/exceeds CGA G-4.1, PED 2014/68/EU, ANSI/ASME B40.1, CRN OH5216

The FSDCDFA Forward Acting Rupture Discs are composite conventional discs formed by three parts: a slotted, perforated metal part, a seal membrane (usually in PTFE but also available in many other metallic or non-metallic materials) and a protection section. It is excellent for use with gas and liquids in static conditions and excellent for low pressures. FSDCDFA discs react to excessive pressure with total opening in a few milliseconds without fragmentation. They are therefore recommended for valve protection. Supports may be provided for vacuum or counter-pressure protection. Composite FSDCDFA rupture discs may also be used for simultaneous protection from pressure and vacuum.
