Introduction: Temperature and Pressure Relief Valves (T/P Valves) rated at 0.7 MPa (102 PSI) are designed for use in various water heating systems. These valves provide critical safety protection by automatically releasing excess temperature and pressure, offering dual protection for sensitive equipment such as solar heaters, electric heaters, heat pumps, and boilers. Features: Temperature and pressure relief valves are commonly used to control pressure in heating system boilers, domestic hot water storage tanks, and general water systems. When the system reaches the calibrated pressure, the valve opens and vents to the atmosphere, preventing dangerous overpressure conditions that could damage system components. Calibration Pressure Options: 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 MPa Pressure Deviation: 0.015 MPa for pressures up to 0.5 MPa; 3% of set pressure for pressures above 0.5 MPa Technical Specifications: Color: Gold Material: Brass body, brass control spindle, silicone gel gasket, SUS304 stainless steel spring Connection Size: 3/4 inch BSPP (female) inlet and outlet Nominal Pressure: PN10 Temperature Range: 5C to 110C Set Pressure Options: 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 MPa Set Pressure Deviation: -10% to +5% of set pressure Set Temperature: 99C Dimensions: 83 mm x 42 mm Weight: 238 g Package Included: 1 x Pressure Relief Valve Note: The package includes only the items listed above.
