CONCOA 213 Series Regulator

The Altecnic / Caleffi Relief Valve - Pushfit Inlet - 312007CST is an essential component for domestic hot water systems, designed to safeguard the hot water cylinder and protect heating systems, including boilers and other critical components. This relief valve is available in a selection of set pressures to meet your specific requirements. As system pressure increases and reaches the predetermined discharge pressure, the valve automatically opens, releasing excess pressure into the atmosphere. This function is crucial in preventing hazardous pressure levels that could endanger the boiler, the hot water storage cylinder, and any personnel nearby.

**Stainless Steel Expansion Vessel for Potable Water Applications** Introducing the Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels, expertly designed to manage the additional load within your water system during the heating process, when water expands in volume. These expansion vessels play a crucial role in maintaining safe operating levels by averting pressure build-up in both sealed heating and cold water systems. Featuring a replaceable membrane, our vessels prevent water from coming into contact with the steel shell, effectively stopping corrosion and contamination, thus ensuring the water remains safe for human consumption. The replaceable membrane allows for convenient servicing in situ, eliminating the need to remove the vessel for maintenance. ### Features and Benefits: - **Corrosion-Resistant**: The stainless steel bolted flange ensures enhanced durability and corrosion prevention. - **Noise Reduction**: An extra wide membrane opening mitigates noise caused by restricted flow, ensuring a quieter system. - **Internal Protection**: The internal membrane provides a barrier, preventing any water contact with the steel shell and eliminating internal corrosion. - **Comprehensive Range**: Available in sizes from 2 to 5000 litres, catering to all applications. - **Effortless Servicing**: Each unit is supplied with a replaceable membrane, allowing for easy servicing without removal. - **Convenient Pre-Charge**: Equipped with a pre-charge valve for easy topping up of air pressure. - **Hot and Cold Water Compatible**: Suitable for use with both hot and cold water systems. ### Specification: - **Capacity**: 1000 Litres - **Colour**: Red - **Pre-Set Pressure (Bar)**: 4 - **Max Pressure (Bar)**: 10.0 - **Minimum Temperature**: -10°C - **Maximum Temperature**: 99°C - **Height**: 2160mm - **Diameter**: 800mm - **Water Connection**: 2" MBSP - **Product Code**: XVES050170 **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 - TÜV Certified - Materials for 1000 - 5000 litre models comply with BS 6920 Ensure the safety and efficiency of your water system with our high-quality stainless steel expansion vessels, designed for reliability and performance.

**Medenus S100 Gas Safety Shut-Off Valve** The Medenus S100 Gas Safety Shut-Off Valve is engineered to effectively terminate gas flow when the outlet pressure in the regulating section deviates from predetermined response limits. This intelligent valve is equipped with an SSV control device that continuously monitors the outlet pressure via a dedicated measurement line. In response to pressure changes, the diaphragm within the control unit adjusts accordingly. When the outlet pressure dips below the designated lower switch-off point or ascends beyond the upper switch-off point, the switch socket linked to the SSV diaphragm shifts to an appropriate disengaged position. This action releases the engaging mechanism's balls, allowing the SSV screw spindle to be retracted. Consequently, the closing spring exerts pressure on the SSV valve plate against the valve seat, ensuring a gas-tight closure of the gas flow. The SSV can only be manually reopened and secured in the open position. To facilitate this, the outlet pressure at the measuring point must either fall below the upper response pressure or rise above the lower response pressure by at least the re-engagement differential amount (Δp). The SSV is adaptable to either functional class A (featuring diaphragm rupture protection) or class B (lacking diaphragm rupture protection), provided it adheres to specific national regulations. Additionally, there is an option to incorporate a remote display indicating the SSV position as “CLOSED”, along with both manual and remote release capabilities, operational during power supply or outages. **Specifications** - **Sizes**: 1" (DN25) to 8" (DN200) - **Connections**: Flanged PN or ANSI - **Medium**: Gas - **Operating Pressure**: 8 Barg - **Release Mechanism**: Lack of pressure and overpressure - **Notes**: Usable in any orientation; features a gas-tight zero position Enhance your gas safety measures with the Medenus S100 Gas Safety Shut-Off Valve, a reliable choice for effective gas flow management.
