CONCOA 205 Series Regulator

The CONCOA 203 Series is a chrome-plated forged brass, single-stage regulator designed for low-pressure delivery of non-corrosive, liquefied, or high-purity inert gases (up to grade 4.5). It provides precise final pressure control from low inlet pressures, with adjustable delivery as low as 0.1 PSIG (7 mBAR) in 0.05 PSIG (4 mBAR) increments, ideal for applications requiring atmospheric or sub-5 PSIG (350 mBAR) outputs.

Features:

• Fine-adjusting screw for precise pressure control

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat design with 360° integral filtration

• Helium leak-tested for integrity

Specifications:

• Max inlet pressure: 200 PSIG (14 BAR)

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

• Gauges: 2½" (63 mm) steel with brass connections

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

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

• Cv: 0.02; Diaphragm: 316L stainless steel

• Helium leak integrity: 1 × 10⁻⁸ scc/sec

• Internal seals: PTFE; Ports: 1/4" FNPT

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