Bailey 707ED Safety Relief Valve Male x Female (EDPM Disk with Dome Top – Suitable for Water & Gas Service (not Air))

**Stainless Steel Expansion Vessel for Potable Water Applications** Introducing the Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels, expertly designed for managing the additional load in water systems during heating, when water volume increases. These expansion vessels play a critical role in maintaining safe operating levels, effectively preventing excessive pressure build-up within both sealed heating and cold water systems. Equipped with a replaceable membrane, these vessels guard against corrosion and contamination, ensuring that the water remains safe for human consumption. The replaceable membrane allows for seamless servicing in situ, eliminating the need for removal and enabling quick maintenance. **Features and Benefits:** - **Corrosion-Resistant Design**: The stainless steel bolted flange construction ensures long-lasting durability and prevents corrosion. - **Minimised Noise**: The extra-wide membrane opening helps to reduce noise caused by restricted water flow. - **Internal Protection**: The internal membrane ensures that water does not come into contact with the steel shell, effectively halting internal corrosion. - **Versatile Capacity Range**: Available in sizes from 2 to 5000 litres, suitable for various applications. - **Easy Servicing**: Each version is supplied with a replaceable membrane, allowing for hassle-free servicing without removal. - **Convenient Pre-Charge Valve**: Includes a pre-charge valve for easy topping up of air pressure. - **Hot and Cold Water Compatible**: Designed specifically for use with hot and cold water systems only. **Specifications:** - **Capacity**: 5 Litres - **Colour**: White - **Pre-Set Pressure**: 3.0 Bar - **Maximum Pressure**: 10.0 Bar - **Minimum Temperature**: -10°C - **Maximum Temperature**: 99°C - **Height**: 304 mm - **Diameter**: 160 mm - **Water Connection**: 3/4” MBSP - **Product Code**: XVES050020 **Materials:** - **Shell**: Epoxy Coated - **Membrane**: EPDM - **Bolted Flange**: Stainless Steel **Standards and Approvals:** - WRAS approved for capacities up to 1000 litres - CE marked in accordance with Directive PED 97/23/CE - TUV Certified - Compliance with BS 6920 for models ranging from 1000 to 5000 litres This stainless steel expansion vessel is an essential component for ensuring the efficiency and safety of your potable water systems.

The CONCOA 302 Series is a four-port, chrome-plated brass, single-stage cylinder regulator designed for primary pressure control of high-purity, non-corrosive, or liquefied gases. Single-stage regulation is recommended for cylinders under 500 PSIG (34 BAR) or applications where minor outlet pressure fluctuations from cylinder depletion are acceptable, or where inlet pressure is stable.
