Introduction: Temperature and Pressure Safety Valves ( / P Valves) 0.7Mpa applies = 101PSI Detailed introduction: Temperature and pressure relief valves ( valves) are suitable for other sensitive heaters such as solar , electric heaters, heat pump , various heating functions (such as boilers). The valve can automatically reduce the temperature and pressure, and has the dual safety protection function of temperature and pressure. It is the safety protector of the current pressure water heater. Features: Safety relief valves are commonly used to control the pressure in boilers in heating , hot water tanks stored in domestic hot water , and general water . When the calibrated pressure is reached, the valve opens and, by venting to the atmosphere, prevents the system from reaching pressure levels that are dangerous to the components in the boiler and the system itself. Calibration pressure: 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 Mpa; Deviation: When not more than 0.5Mpa, the deviation is 0.015Mpa, and when it is 0.5Mpa, the deviation is 3% of the rated pressure.
