Introduction: Temperature and Pressure Safety Valves (T/P Valves) 0.7 MPa equals 102 PSI Detailed introduction: Temperature and pressure relief valves are suitable for various water heaters including solar, electric, heat pump, and boiler systems. The valve automatically releases excess temperature and pressure, providing dual safety protection for pressurized water heating systems. Features: Safety relief valves are commonly used to control pressure in heating system boilers, domestic hot water storage tanks, and general water systems. When the set pressure is reached, the valve opens to release pressure into the atmosphere, preventing dangerous overpressure conditions in the system and its components. Calibration pressures available: 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 MPa; Tolerance: For pressures up to 0.5 MPa, deviation is 0.015 MPa; for pressures above 0.5 MPa, deviation is 3% of the rated pressure.
