Enhance your systems with our high-quality pressure relief valves available in 1/4" to 1/2" sizes. These valves feature female NPT inlet and outlet connections, ensuring easy installation in various applications. Crafted from durable 316L stainless steel and fitted with either PTFE or PEEK disks, they are designed to handle medium gases efficiently. With set pressure capabilities ranging from 0.5 to 650 Barg via a 6mm orifice, and a wide temperature tolerance between -45°C and +200°C, these valves meet diverse operational needs. Additionally, our products comply with PED approvals, ensuring reliability and safety in your industrial processes.

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.
