The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact devices designed to protect against over-pressurisation within unvented hot water systems. These valves are essential for safeguarding your system in the event that temperature or pressure controls fail. Engineered for installation at the upper section of a hot water cylinder, the TPR15 valves effectively monitor the highest temperatures within the system. When the temperature exceeds 95°C, the wax mixture inside the temperature probe expands, raising the valve off its seat and allowing water to escape, thus reducing the pressure within the cylinder. In cases where water pressure increases without a corresponding temperature rise, the valve remains closed until the set pressure of the relief mechanism is reached, at which point it opens to relieve excess pressure. Select models feature a PTFE coating on the Male BSP (MBSP) inlet thread, facilitating quicker, hassle-free installation.

Introducing the FSKRDRA Reverse Acting Rupture Discs, a cutting-edge solution utilising the latest technology in the industry. Designed with a unique camber, the convex disc maintains its shape under operating pressure, only altering when reverse pressure is reached. This innovative device operates with pressure ratios of up to 95% between operating and rupture pressure, demonstrating exceptional reliability through thousands of cycles. Upon reversion, the disc ruptures in just a few thousandths of a second along a scored line, ensuring complete opening without any fragmentation. These rupture discs exhibit lower sensitivity to temperature variations compared to traditional discs, making them ideal for applications with significant temperature fluctuations. Their advanced design allows for use solely in liquid applications and in cycling or pulsating conditions, all while maintaining safety margins. Moreover, they are particularly effective for isolating safety valves. With a wide selection of materials and thicknesses, FSKRDRA discs offer excellent resistance to corrosion. For enhanced protection, a PTFE lining can be applied to the process side of the disc. Notably, vacuum support is unnecessary, and these discs are capable of enduring high counter-pressures. ### Technical Specifications: - **Sizes:** From 1" (DN25) to 36" (DN900) - **Materials:** Available in Stainless Steel, Alloy 201, Alloy 400, Alloy 600, Alloy 625, Alloy C276, and Titanium - **Rupture Pressure:** Ranges from 0.41 bar g (6 psi g) to 137 bar g (2000 psi g), depending on the material and diameter - **Krl:** 0.48 - **Tolerance:** +/- 5% to +/- 20% - **Temperature Range:** From -196 °C to 480 °C - **Operating Margin:** Typically 90%, with the potential to reach 95% subject to service conditions - **Fragmentation:** None (will not disintegrate upon bursting) - **Use Under Valve:** Yes - **Corrosion Resistance:** Excellent - **Linings:** Available - **Container Types:** FSHR/A, FSHR/P, FSHR/F, FSHTC - **Rupture Sensor Options:** Electrical, Magnetic, Inductive, Optical - **Certifications:** ASME Certification (UD Stamp), PED Certification (CE Stamp), ATEX EX II 2 GD Certification available For further information and to request a rupture disc, please download our Rupture Disc Request Form.
