Medenus R100UD Gas Vacuum Regulator

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.

The FSSCDF Forward Acting Rupture Discs feature precision micro-scored sections that open in controlled petals, using four, six, or more radial score lines to ensure a clean, reliable opening while minimising the risk of petal separation. This design makes them particularly well suited for high burst pressure applications and for systems operating under cycling or pulsating conditions with gases or liquids, without compromising safety margins.

These discs respond to overpressure within milliseconds, opening fully without fragmentation, and are ideal for protecting safety relief valves. They support an operating-to-burst pressure ratio of up to 85%, offer excellent corrosion resistance, and can be further enhanced with an optional PTFE lining. In many applications, the discs can also withstand full vacuum conditions without additional supports, providing flexible installation options.
