Besa 241 Safety Valve

The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact devices meticulously engineered to safeguard against overpressurisation within unvented hot water systems. This crucial protection comes into play if the temperature or pressure controls fail. These valves are designed to be installed at the upper section of a hot water cylinder, where the highest temperatures can typically be found. In the event that the system temperature exceeds 95°C, the wax mixture within the temperature probe's element expands, causing the valve to lift off its seat and release water to waste. This process effectively alleviates excess pressure within the cylinder. Additionally, if the water pressure increases without a corresponding rise in temperature, the valve remains closed until it reaches the set pressure of the relief mechanism, at which point it opens to relieve the excess pressure. Certain models feature a PTFE coating on the MBSP inlet thread, significantly enhancing installation efficiency. ### Features and Benefits: - Provides protection against temperatures exceeding 95°C - Prevents dangerous overpressurisation - Twist-top cartridge design facilitates easy servicing - Available in a variety of pressure settings and probe lengths - Some models include a PTFE coating for added convenience ### Specification: - **Size:** 1/2" x 15mm - **Connections:** BSP Male Inlet x Compression Outlet - **Materials:** Brass - **Medium:** Hot water only - **Set Pressure (Set & Locked):** 6 Barg - **Temperature Relief:** +90 to 95 °C - **Discharge Capacity:** 10 kW - **Probe Length:** 95 mm - **Product Code:** PTEM550857 - **Notes:** Includes PTFE, WRAS approved Ensure the safe operation of your unvented hot water system with the RWC TPR15 Pressure and Temperature Relief Valves, an essential investment for any modern heating system.

The Resideo F78TS flanged reverse rinsing filters are designed for installations that require a high demand for water. These filters are ideal for large residential buildings, central water supply systems, and various commercial or industrial applications. The F78TS models feature the same advanced reverse rinsing filtration system found in our range of household fine filters. Additionally, they can be retrofitted with the Z11AS fully automatic reverse rinsing actuator and the DDS76 differential pressure switch. This fine filter effectively prevents the ingress of foreign materials, such as rust particles, strands of hemp, and grains of sand, thereby minimising the risk of corrosion.
