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

**Stainless Steel Expansion Vessel for Heating Applications** Introducing the Reliance Valves Aquasystem Heating Expansion Vessels, crafted from high-quality stainless steel. Our vessels cater to a wide range of heating applications, with capacities available from 2 litres to an impressive 5000 litres. These vessels can withstand maximum pressures ranging from 8.0 to 10.0 bar. Designed with replaceable membranes, the Aquasystem series allows for in-situ servicing, ensuring that the internal steel shell remains free from water contact. This innovative design helps prevent internal corrosion, significantly extending the lifespan of the vessel. **Features and Benefits:** - **Corrosion-Resistant Design**: The stainless steel bolted flange offers superior protection against corrosion. - **Noise Reduction**: The extra-wide membrane opening mitigates noise that can arise from restricted water flow. - **Durable Internal Membrane**: Ensures no water contact with the steel shell, effectively halting internal corrosion. - **Versatile Capacity Range**: Available in sizes from 2 to 5000 litres, making it suitable for various heating applications. - **Serviceable in Situ**: Each unit comes with a replaceable membrane, allowing for maintenance without the need to remove the vessel. - **Convenient Pre-Charge Valve**: Easily top up air pressure as needed. - **Application-Specific**: Designed exclusively for heating applications. **Specifications:** - **Capacity**: 35 Litres - **Colour**: Red - **Pre-Set Pressure (Bar)**: 1.5 - **Maximum Pressure (Bar)**: Up to 500 Litres - 8.0 bar; 750 Litres and above - 10.0 bar - **Minimum Temperature**: -10°C - **Maximum Temperature**: 99°C - **Height**: 440mm - **Diameter**: 365mm - **Water Connection**: 3/4" MBSP **Product Code**: XVES100070 **Materials**: - Shell: Epoxy Coated Steel - Membrane: EPDM - Bolted Flange: Galvanised Steel **Standards and Approvals**: - CE marked in accordance with Directive PED 97/23/CE - TUV Certified Enhance your heating system's efficiency and lifespan with the Reliance Valves Aquasystem Heating Expansion Vessel.
