AURA EXC Compact Single Stage Pressure Reducing Regulator

**Stainless Steel Expansion Vessel for Heating Applications** Introducing the Reliance Valves Aquasystem Heating Expansion Vessels, expertly crafted from stainless steel to meet a wide range of heating applications. Available in capacities from 2 litres to 5000 litres, our vessels are designed to operate under maximum pressure ratings from 8.0 to 10.0 bar, ensuring reliability and efficiency. One of the standout features of the Aquasystem range is the innovative design that incorporates replaceable membranes. This allows for servicing in situ, meaning that the vessel can be maintained without removal. This crucial design element prevents water from contacting the steel shell, significantly reducing the risk of internal corrosion and thereby extending the overall lifespan of the vessel. **Key Features and Benefits:** - **Corrosion-Resistant Design:** The stainless steel bolted flange provides superior protection against corrosion. - **Enhanced Flow for Quiet Operation:** An extra-wide membrane opening minimises noise caused by restricted flow. - **Internal Protection:** The internal membrane prevents any water contact with the steel shell, effectively halting internal corrosion. - **Versatile Capacity Range:** With options from 2 to 5000 litres, there is a vessel suitable for every application. - **Easy Maintenance:** All models are equipped with a replaceable membrane, allowing for simple servicing without the need to remove the vessel. - **Convenient Pre-Charge Valve:** Easily top up air pressure as required. - **Application Specific:** Designed specifically for heating applications. **Specifications:** - **Capacity:** 18 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:** 430 mm - **Diameter:** 280 mm - **Water Connection:** 3/4" MBSP - **Product Code:** XVES100050 **Materials:** - **Shell:** Epoxy Coated Shell - **Membrane:** EPDM - **Bolted Flange:** Galvanised Steel **Standards and Approvals:** CE marked according to Directive PED 97/23/CE - TUV Certified.

Four-Port, Brass Barstock, High Flow Pipeline Regulator for High Purity Inert Gas Applications

The CONCOA 483 Series regulator is designed for high flow inert gas applications, including bulk gas distribution, high purity chamber pressurization, and liquefied hydrocarbon analysis. Its internal pressure equalization minimizes delivery pressure variations typical in pipeline systems. Rated to full cylinder pressure, the 483 Series ensures safe operation even in the event of primary pressure control failure.
