Reliance RWC TPR22 Pressure & Temperature Relief Valve 3/4

Reliance RWC TPR22 Pressure & Temperature Relief Valve 3/4" x 22mm 7 Bar - PTEM575205

The Reliance Water Controls (RWC) TPR22 Pressure & Temperature Relief Valves are expertly designed compact valves that ensure protection against over pressurisation in unvented hot water systems. These essential valves are mounted at the upper part of a hot water cylinder, where the hottest temperatures are found. Should the system exceed 95°C, the specially formulated wax mixture within the temperature probe expands, lifting the valve off its seat to release water, thereby alleviating pressure within the cylinder. Furthermore, in the event of increased water pressure (without a corresponding temperature rise), the valve remains closed until the designated pressure limit of the relief mechanism is reached. At that point, the valve opens to relieve excess pressure. Some variants are available with a PTFE coating on the MBSP inlet thread, facilitating quicker installation.

Features and Benefits:

  • Protects against temperatures exceeding 95°C
  • Prevents over pressurisation
  • Twist-top cartridge design for effortless servicing
  • Available in a variety of pressure settings and probe lengths
  • Select models come complete with a PTFE coating

Specifications:

  • Size: 3/4" x 22mm
  • Connections: BSP Male Inlet x Compression Outlet
  • Materials: Brass
  • Medium: Hot water only
  • Set Pressure (Set & Locked): 7 Barg
  • Temperature Relief: +90 to 95°C
  • Discharge Capacity: 25kW
  • Probe Length: 95mm
  • Product Code: PTEM575205
  • Notes: With PTFE, WRAS approved

Ensure the integrity of your hot water system with the reliable and efficient RWC TPR22 Pressure & Temperature Relief Valves, providing safety and peace of mind in your home.

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.
