CONCOA 206 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

Four-Port, Chrome-Plated Brass Barstock, Rear-Entry Point-of-Use Regulator for High Purity Inert Gases

The CONCOA 307 Series regulator provides secondary pressure control for non-corrosive, liquefied, and ultra-high purity inert gases (up to grade 5.5). It is ideal for point-of-use pressure regulation in high purity gas distribution systems or for applications that can tolerate minor outlet pressure fluctuations due to diminishing supply or where inlet pressure is constant or below 500 PSIG (34 BAR). Rated to at least 3000 PSIG (210 BAR), the 307 Series rear-entry regulator is commonly used in laboratory installations and point-of-use panels.

Features

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat design with integral 360° filtration

• Low wetted surface area reduces purge requirements

• Spectrometric helium leak check confirms leak integrity

Specifications

• Max inlet pressure (bare body): 3000 PSIG (210 BAR)

• Body: Chrome-plated brass barstock

• Seat: PTFE

• Filter: 10‑micron sintered bronze

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

• Diaphragm: 316L stainless steel

• Cv: 0.1

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

• Internal seals: PTFE

• Ports (bare body): 1/4 in FNPT
