Resideo Braukmann D04FM Pressure Reducing Valve - Compression Fitting

The Rhodes 903 Sight Glass with Integral Spout is a dual-sided flow indicator designed to enhance visibility of clear liquids. Featuring an integral spout that generates a jetting action for turbulent flow, this sight glass significantly improves the observation of liquid flow, colour, and condition, thereby enabling better quality assurance and consistency checks.

These indicators are engineered for versatile installation, suitable for both vertical and horizontal orientations. The spout not only facilitates easy viewing but also serves as a drip indicator, effectively indicating valve leaks, distillation processes, or similar conditions. Available in a variety of materials, the Rhodes Sight Glasses are proudly manufactured in the UK, utilising local castings, unlike many competitors that source components from overseas.

The Reliance Valve's Anti-Legionella Valve is specifically engineered to safeguard against harmful bacteria like Legionella by ensuring continuous water circulation and eliminating stagnation in stored cold water within expansion vessels. Available in a variety of sizes, this valve is suitable for applications ranging from point-of-use water heater expansion vessels to larger plant room storage tanks. By converting a standard single connection expansion vessel into a ‘flow-through’ type, the Anti-Legionella Valve diverts part of the flow into the vessel, thereby continuously renewing the water and reducing the likelihood of stagnation that can lead to bacterial growth.

Features and Benefits:

• Keeps water circulating through the expansion vessel
• Prevents water stagnation
• Simple installation process
• Integrated ball valve and drain valve for hassle-free servicing and maintenance
• Compatible with any standard vessel featuring 1/2", 3/4", 1" or 1 1/4" connections
• Designed exclusively for cold water applications
• Only suitable for use with copper piping
• Anti-Legionella models ANTI110003 and ANTI110004 include a locking mechanism
