Introduction: Temperature and Pressure Relief Valves (T/P Valves) 0.7 MPa equals 102 PSI Detailed introduction: Temperature and pressure relief valves are suitable for use with various types of water heaters, including solar, electric, heat pump, and boiler systems. The valve automatically releases excess temperature and pressure, providing dual protection for the system. It serves as a safety device for pressurized water heating systems. Features: 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 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 Materials: - Body: 3/4 inch brass - Control spindle: Brass - Sealing gasket: Silicone gel - Spring: SUS304 stainless steel Nominal pressure: PN10 Temperature range: 5°C to 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°C Inlet and outlet connection: BSPP 3/4" x 3/4" Weight: 238g Dimensions: 83mm x 42mm Package included: 1 x Pressure Relief Valve Note: The package includes only the items listed above.
