Rhodes 901 Sight Glass with Flow Fingers

The CONCOA 213 Series is a chrome-plated forged brass, dual-stage regulator designed for primary pressure control of low-pressure, non-corrosive, liquefied, or high-purity inert gases (up to grade 4.5). Its two-stage design ensures stable delivery pressure, compensating for cylinder depletion, with adjustable outputs as low as 0.1 PSIG (7 mBAR) in 0.05 PSIG (4 mBAR) increments, making it ideal for atmospheric or sub-5 PSIG (350 mBAR) applications.

Features:

• Fine-adjusting screw for precise pressure control

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat design with 360° filtration in both stages

• Standard relief valve protects diaphragm and gauges

• Helium leak-tested for integrity

Specifications:

• Max inlet pressure: 3000 PSIG (210 BAR); optional 4500 PSIG (310 BAR)

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

• Filter: 10-micron sintered bronze

• Diaphragm: 316L stainless steel; Internal seals: PTFE

• Temperature range: -40°F to 140°F (-40°C to 60°C); Cv: 0.02

• Gauges: 2½" (63 mm) steel with brass connection (outlet), 2½" (68 mm) plated case (inlet)

• Seats: PCTFE (first stage), PTFE (second stage)

• Ports: 1/4" FNPT

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