SAFETY VALVE WITH THERMOSTAT 3 BAR - 90 ° C 3/4

Operating Principle: The dual-function safety valve with thermostat controls and limits the temperature and pressure of the hot water by preventing temperatures above 100 ° C. To achieve this, the valve discharges a sufficient amount of water into the atmosphere so that the temperature and pressure return within the operating limit of the system. The valve opens when it reaches the settings for: - Temperature: The composite thermostat inside the temperature sensor immersed in the hot water storage heater, expands as the temperature increases. This expansion causes the piston to move and activate at the valve opening. The valve is set to open at temperatures above 90 ° C. - Pressure: The piston with a preloaded spring, opens when it exceeds the preset pressure. The pressure setting is selected according to the maximum allowable pressure in the system. As the temperature and pressure decrease, the valve closes again and restores the pressure and temperature to the specified tolerances.
