The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve - 309570CST is designed to effectively regulate and limit the temperature and pressure of hot water in domestic storage heaters. By preventing the water from exceeding 100°C and the formation of steam, this valve ensures safety and efficiency. Once the set parameters are reached, the valve expels an adequate amount of water into the atmosphere, allowing the temperature and pressure to return to safe operating limits. The mechanism of the valve operates as follows: - **Temperature Control**: The thermostat compound within the temperature sensor, which is submerged in hot water, expands as the temperature rises. This expansion drives a thrust pin that acts on the obturator, thereby opening the valve. The valve is calibrated to open when the temperature exceeds 90°C. - **Pressure Control**: When the pressure reaches the predetermined setting, the obturator, which is countered by a set spring, lifts and fully opens the outlet. The pressure setting is selected based on the maximum allowable pressure within the system. As temperature and pressure decrease, the valve automatically re-closes within the specified tolerances.
