The Reliance PTEM585210 temperature and pressure relief (TPR) valve is designed for use in unvented hot water systems, providing critical safety protection by relieving excess temperature and pressure within the cylinder. Featuring a 3/4" male BSP inlet and 22mm compression outlet, along with a 95mm probe, this valve is factory set to operate at 10 bar and is constructed with a durable brass body for long-term reliability.
TPR valves are essential safety components that automatically discharge water when system temperature or pressure exceeds safe limits, helping prevent damage to the cylinder and reducing the risk of hazardous failure. The integrated temperature probe responds to rising water temperatures (typically around 90–95°C), while the pressure mechanism ensures excess pressure is safely released. Over time, valves may degrade due to scale build-up, wear, or repeated operation, which can lead to leaks or unreliable performance. Replacing a faulty valve restores system safety, ensures compliance with regulations, and maintains proper operation. Installation must always be carried out by a suitably qualified professional in accordance with current regulations.
