Refrigeration Suction Filters

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 Altecnic / Caleffi 309 Pressure & Temperature Relief Valve - 309400CST is designed to effectively control and limit the temperature and pressure of hot water in domestic storage heaters. This essential safety valve ensures that water temperatures do not exceed 100°C, preventing steam formation. When the temperature or pressure reaches its set limits, the valve releases a sufficient amount of water into the atmosphere, ensuring that both temperature and pressure return to safe operating levels.

**How It Works:**

The valve features a thermostat compound within the temperature sensor that is submerged in the hot water storage heater. As the temperature increases, the compound expands, moving a thrust pin that activates the obturator, thereby opening the valve. This mechanism is set to initiate opening at temperatures exceeding 90°C. Regarding pressure, the obturator, which is countered by a spring, lifts when the pressure reaches its designated limit, fully opening the outlet. The pressure setting is predetermined based on the system's maximum permissible pressure. As the temperature and pressure decrease, the valve automatically re-closes within the specified tolerances.
