Reliance RWC TPR28 Pressure & Temperature Relief Valve 1

Reliance RWC TPR28 Pressure & Temperature Relief Valve 1" x 28mm 7 Bar - PTEM100050

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

Reliance RWC TPR15 Pressure & Temperature Relief Valve 15mm x 15mm 7 Bar - PTEM550953

Reliance RWC TPR15 Pressure & Temperature Relief Valve 15mm x 15mm 7 Bar - PTEM550953

**Product Description: Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves** The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are expertly designed compact units that safeguard against the risks of over-pressurisation in unvented hot water systems. Such over-pressurisation can occur if temperature or pressure controls fail. These valves are specifically engineered to be installed at the upper section of a hot water cylinder, where the highest temperatures in the system are typically found. When the temperature exceeds 95°C, the wax mixture within the temperature probe element expands, lifting the valve off its seat and allowing water to escape, thereby relieving pressure within the cylinder. Additionally, the valve remains closed in the event of rising water pressure without a corresponding temperature increase. It will only open once the pre-set pressure threshold of the relief mechanism is reached, effectively releasing any excess pressure. Certain models come with a PTFE coating on the MBSP inlet thread, which streamlines the installation process, saving you valuable time. **Key Features and Benefits:** - Provides protection against temperatures exceeding 95°C - Prevents over-pressurisation in hot water systems - Twist-top cartridge design allows for easy servicing - Available in a range of pressure settings and probe lengths - Some models include a PTFE coating for enhanced installation efficiency **Specification:** - **Size:** 15mm x 15mm - **Connections:** Compression Inlet x Compression Outlet - **Materials:** Brass - **Medium:** Hot water only - **Set Pressure (Set & Locked):** 7 Barg - **Temperature Relief:** +90 to 95°C - **Discharge Capacity:** 10kW - **Probe Length:** 200mm - **Product Code:** PTEM550953 - **Notes:** Long probe, WRAS approved Enhance the safety and efficiency of your hot water system with the RWC TPR15 Pressure and Temperature Relief Valves – the trusted choice for reliable temperature and pressure control.
