Valfonta Model 253 Steam Reheater Injector

The Reliance Water Controls (RWC) TPR22 Pressure & Temperature Relief Valves are compact relief valves specifically designed to safeguard against over-pressurisation within unvented hot water systems. Should the input temperature or pressure controls fail, these valves provide essential protection. They are optimally installed at the upper section of a hot water cylinder, where the highest temperatures are typically found. When the system exceeds 95°C, the wax mixture within the temperature probe element expands, lifting the valve off its seat and allowing water to discharge, thereby alleviating the pressure within the cylinder. In instances of increased water pressure without a corresponding temperature rise, the valve will remain closed until the designated relief mechanism pressure is reached, at which point it will open to release the excess pressure. Certain models feature a PTFE coating on the MBSP inlet thread, streamlining the installation process and saving valuable time.

Introducing the Rhodes 400B Sight Glass with Ball Indicator, an affordable and accessible sight flow indicator designed for optimal performance, featuring a high sensitivity ball that operates from just 0.7 l/m (water). Constructed with nitrile seals and a PTFE ball, this indicator boasts exceptional chemical resistance, further enhanced in the stainless steel variant by the inclusion of borosilicate glass as standard.

This compact sight flow indicator is widely utilised in plant protection applications, effectively displaying coolant or lubrication flow to pumps, compressors, and engines. The 'ball type' design requires horizontal mounting for accurate functionality. Unlike many competitors that source components from the Far East, Rhodes Sight Glasses are fully manufactured in the UK, utilising locally-sourced castings.

Available Sizes: 1/4", 3/8", 1/2", 3/4", 1"

Connection Type: Female BSPT Inlet x Female BSPT Outlet

Materials: Gunmetal or Stainless Steel Body, Nitrile O Ring

Maximum System Pressure: 7 Barg (Gunmetal) / 16 Barg (Stainless Steel)

Temperature Resistance: Up to 100°C Max

Additional Information: Fully compliant with the Pressure Equipment Directive (PED). Proudly manufactured in the UK.

Optimize your system's efficiency with the Rhodes 400B Sight Glass, a robust and reliable choice for flow indication in various industrial applications.
