Reliance RWC TPR15 Pressure & Temperature Relief Valve 1/2" x 15mm 10 Bar - PTEM550853

The Reliance Water Controls (RWC) TPR28 Pressure and Temperature Relief Valve is designed to safely discharge water, effectively preventing damage to hot water cylinders caused by excess pressure or high temperatures. These high-capacity valves are essential for both domestic and commercial applications, ensuring protection against over-pressurisation and temperatures exceeding 95°C. Such conditions can arise in unvented hot water systems if input temperature or pressure controls fail. The TPR28 Valve is specifically designed for installation at the upper section of a hot water cylinder, where the water reaches its highest temperatures. When activated, the valve lifts off its seat, allowing water to be released safely, thereby reducing both pressure and temperature within the cylinder.

**Features and Benefits:**

• High-capacity protection suitable for both domestic and commercial use.
• Prevents water temperatures from exceeding 95°C.
• Safeguards against over-pressurisation for enhanced safety.
• Equipped with a lever-style easing mechanism for ease of use.
• Available in various connection sizes to meet different system requirements.

**Specifications:**

• Size: 1" x 28mm
• Connections: BSP Male Inlet x Compression Outlet
• Materials: Brass
• Medium: Hot water only
• Set Pressure (Set & Locked): 7 Barg
• Temperature Relief: +90 to 95 degrees C
• Discharge Capacity: 50kW
• Probe Length: 195mm
• Product Code: PTEM100050

Notes: WRAS approved

The Reliance Water Controls (RWC) TPR15 Pressure & Temperature Relief Valves are compact, yet highly effective, valves designed specifically to protect your unvented hot water system from the dangers of over-pressurisation. This critical safety feature is essential, as over-pressurisation can occur if the input temperature or pressure controls fail. The valves are strategically designed to be installed at the top of a hot water cylinder, where the highest temperatures are typically found. Should the temperature exceed 95°C, the wax mixture in the temperature probe's element will expand, lifting the valve from its seat and allowing excess water to be discharged safely. Additionally, if water pressure increases without a corresponding temperature rise, the valve remains closed until the pre-set pressure of the relief mechanism is reached, at which point it opens to relieve the excess pressure. Some models are equipped with a PTFE coating on the MBSP inlet thread, facilitating a quicker and more efficient installation process.

Features and Benefits:

• Protects against temperatures exceeding 95°C
• Prevents over-pressurisation in hot water systems
• Innovative twist-top cartridge design for straightforward servicing
• Variety of pressure settings and probe lengths available
• Some models feature a PTFE coating for easy installation

Ensure the safety and reliability of your hot water system with the RWC TPR15 Pressure & Temperature Relief Valves, an essential component for maintaining optimal performance and peace of mind.

The Medenus R101 Gas Pressure Regulator guarantees a stable outlet pressure even when the primary inlet pressure fluctuates. Designed to quickly adapt to changing flow rates, it effectively manages pressure regulation during variable gas usage. Additionally, the Medenus R101 is available in a configuration that functions as a pressure relief valve, making it suitable for applications such as gas torches. This versatile regulator complies with the DVGW Code of Practice G260/262 and is suitable for all neutral and non-corrosive gases (with additional options available upon request). The Medenus R101 can be obtained with flange connections ranging from DN25 to DN100, and it operates at working pressures of up to 8 bar. All gas pressure regulators are certified by DVGW and CE.
