**Altecnic / Caleffi 309 Pressure & Temperature Relief Valve (309500CST)** The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve (model 309500CST) is expertly designed to monitor and regulate the temperature and pressure within domestic storage heaters. This valve plays a crucial role in preventing the water temperature from exceeding 100°C and averting the dangerous formation of steam. Once the specified limits are reached, the valve automatically discharges an adequate quantity of water, ensuring that both temperature and pressure are safely maintained within the system's operational parameters. **Operational Mechanism:** 1. **Temperature Regulation:** The valve's thermostat compound, housed within the temperature sensor submerged in the hot water storage heater, expands with a rise in temperature. This expansion causes a thrust pin to move, which in turn activates the obturator, resulting in the opening of the valve. The valve is calibrated to open when temperatures exceed 90°C. 2. **Pressure Regulation:** The obturator is countered by a predetermined spring. Upon reaching the designated pressure setting, the obturator elevates, fully opening the outlet. The pressure setting is based on the maximum allowable pressure for the system. As temperature and pressure lower, the valve automatically re-closes within the established tolerances. **Specifications:** - **Size:** 3/4" - **Connections:** Male x Ø 22 mm, featuring a compression fitting for copper piping - **Materials:** DZR (Dezincification Resistant) - **Medium:** Water - **Set Pressure:** 10 Barg - **Discharge Rating:** 25 kW - **Temperature Setting:** 90°C - **Probe Length:** 99 mm - **Product Code:** 309500CST - **Certifications:** WRAS approved, CE marked Ensure the safety and efficiency of your hot water system with the reliable Altecnic / Caleffi 309 Pressure & Temperature Relief Valve. Perfectly suited for domestic use, this valve meets strict industry standards while optimising your heating system's performance.
