Introduction: Temperature and Pressure Safety Valves (T or P Valves) 0.7Mpa applies = 102PSI Detailed introduction: Temperature and pressure relief valves (TP valves) are suitable for other sensitive heaters such as solar water heaters, electric heaters, heat pump water heaters, various heating functions (such as boilers). The TP 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 systems, hot water tanks stored in domestic hot water systems, and general water systems. 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 greater than 0.5Mpa, the deviation is 3 percent of the rated pressure.
