**Rhodes 913 Sight Glass with Integral Spout – Enhanced Viewing for Clear Liquids** The Rhodes 913 Sight Glass features an integral spout designed to create a jetting action that induces turbulent flow, significantly enhancing the visibility of clear liquids. Its generous viewing area enables easy observation of flow, colour, and condition, allowing for effective assessments of product quality and consistency. These indicators are versatile, suitable for both vertical and horizontal installation. The integrated spout also serves as a drip indicator, making it ideal for detecting valve leaks, distillation processes, or other similar conditions. With a range of materials available as standard, Rhodes Sight Glasses are proudly manufactured in the UK, utilising locally-sourced castings unlike many competitors who rely on components from overseas. **Product Specifications:** - **Sizes:** Available in dimensions from 1/2" to 4" - **Connections:** Flanged options available for most types - **Materials:** Constructed from a durable cast iron body, mild steel covers, and graphite gaskets - **Maximum System Pressure:** 16 Barg - **Operating Temperature Range:** -10°C to 180°C - **Compliance:** Fully compliant with the Pressure Equipment Directive (PED) and entirely manufactured within the UK.

The Altecnic / Caleffi 311 Safety Valve - 311460 is an essential component for domestic hot water systems, providing crucial protection for hot water cylinders and heating systems, including boilers and associated components. This valve is specifically chosen based on the required set pressure. When the pressure within the system exceeds the designated threshold, the valve activates, releasing excess pressure into the atmosphere. This mechanism effectively prevents potentially dangerous pressure levels that could harm the boiler, hot water storage cylinder, or anyone nearby.
