Reliance RWC 300 Litre Heating Expansion Vessel Tank with Replaceable Membrane Pre Set 1.5 Bar - XVES100140

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
