Turbine Flow Meter Sensor with Built-in Frequency to Current Converter

The Altecnic / Caleffi 312 Safety Valve - 312425 is an essential component for domestic hot water systems, designed to safeguard hot water cylinders and heating systems, including boilers and other critical components. This safety valve is chosen based on the specific set pressure required for your system. As pressure increases and reaches the predetermined discharge pressure, the valve opens, allowing excess pressure to escape to the atmosphere. This vital function prevents the internal pressure from escalating to levels that could pose a risk to the boiler, hot water storage cylinder, and the safety of personnel nearby.

The Resideo Braukmann D06F pressure reducing valve is designed to safeguard domestic drinking water installations from high pressure and pressure surges in accordance with EN 806-2 standards. Renowned as one of the most widely used pressure reducing valves (PRVs) across the UK and Europe for potable water applications, the D06F effectively moderates the incoming supply pressure to properties, even in instances of significant fluctuations at the inlet. This versatile pressure reducing valve is appropriate for domestic, industrial, and commercial installations.

It is important to note that the version of the Resideo D06F we offer comes equipped with a brass filter bowl, as the variant featuring a clear bowl does not hold WRAS approval.
