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, and heat pump systems, as well as boilers and other heating appliances. 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 preset pressure is reached, the valve opens to release pressure into the atmosphere, preventing dangerous overpressure conditions in the system and its 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 the set pressure for pressures above 0.5 MPa Technical specifications: Color: Gold Materials: Body: 3/4 inch brass Control spindle: Brass Sealing gasket: Silicone gel Spring: SUS304 stainless steel Nominal pressure: PN10 Temperature range: 5–110 °C 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: 99 ± 4 °C Inlet and outlet (thread type): BSPP 3/4" x 3/4" Weight: 238 g Dimensions: 83 x 42 mm Package included: 1 x Pressure Relief Valve Note: The package includes only the items listed above.
