Bailey 707VL Safety Relief Valve Male x Female (AFLAS Disk with Lever – Suitable for Gas Service)

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.
