Introduction: Temperature and Pressure Safety Valves (T/P Valves) 0.7 MPa equals 101 PSI Detailed introduction: Temperature and pressure relief valves are suitable for use with various water heaters, including solar water heaters, electric water heaters, heat pump water heaters, and boilers. The valve automatically releases excess temperature and pressure, providing safety protection for pressurized water heating systems. It serves as a critical safety component for current pressure water heaters. Features: Safety relief valves are commonly used to control pressure in boilers within heating systems, 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 the boiler or system 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 Pressure deviation: 0.015 MPa for pressures up to 0.5 MPa; 3% of rated 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: 5110C 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 Inlet and outlet connection: BSPP 3/4" x 3/4" Weight: 238g Dimensions: 83 x 42mm Package included: 1 x Pressure Relief Valve Note: The package includes only the items listed above.
