The Reliance Valves 100 Series Pressure Relief Valves, crafted from hot pressed brass, are primarily designed to safeguard closed-circuit wet heating systems from excessive pressure build-up. **Product Features:** - **High Flow Design:** Specifically tailored for larger capacity systems, ensuring effective water discharge. - **Optimised Outlet Size:** The outlet is intentionally larger than the inlet to facilitate elevated discharge flow rates. - **Overpressure Protection:** Provides essential protection against over-pressurisation in wet heating systems, ensuring system longevity and safety. - **Enhanced Scale Resistance:** The diaphragm design improves resistance to scale, enhancing the valve's performance and durability. - **Cartridge Design:** Simplifies maintenance by allowing easy servicing and replacement without needing to reset the response pressure. - **Versatile Pressure Range:** Adjustable pressure settings from 2.5 to 5.0 bar accommodate various system requirements, with the specific response pressure clearly indicated on the twist cap. - **Increased Discharge Capacity:** The high lift design significantly boosts discharge capability, making it ideal for demanding applications. - **Heating Applications Only:** Specifically designed for heating systems, ensuring optimal performance. **Specifications:** - **Size:** 1/2" x 3/4" - **Connections:** BSP Female Inlet x BSP Female Outlet - **Materials:** Hot pressed DZR Brass - **Medium:** Water - **Set Pressure:** 3 Barg - **Temperature Rating:** Up to +140°C - **Product Code:** PREL100001 - **Certification:** WRAS approved Upgrade your heating system's safety and efficiency with the PREL100001 High Capacity Sealed Heating System Pressure Relief Valve—your trusted solution for reliable pressure management.

The Altecnic / Caleffi Relief Valve - Pushfit Inlet - 312408 BRT is designed for use in domestic hot water systems, providing essential protection for hot water cylinders. Additionally, this relief valve safeguards heating systems, such as boilers and other critical components. The valve is chosen based on the required set pressure; as the pressure within the system increases and reaches the designated discharge pressure, the valve opens, releasing excess pressure to the atmosphere. This action prevents potentially dangerous pressure levels that could affect the boiler, hot water storage cylinder, and personnel nearby.

The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact yet robust solutions, expertly designed to safeguard against over-pressurisation in unvented hot water systems. These essential valves are specifically intended for installation at the upper section of a hot water cylinder, where the highest temperatures are typically encountered. In the event that the system temperature exceeds 95°C, the wax mixture within the temperature probe's element expands, lifting the valve off its seat to release water safely, thereby alleviating pressure within the cylinder. Furthermore, if water pressure escalates without a corresponding temperature rise, the valve remains shut until the predefined pressure of the relief mechanism is reached, at which point it will open to release excess pressure. Certain models feature a PTFE coating on the Male BSP inlet thread, facilitating a quicker and more efficient installation process.
