WAKI Pressure Cooker is a good combination of low pressure cookers and high pressure cookers. You can choose cooking pressure from 0 to 45 kPa for low pressure cooking and from 45 to 90 kPa for high pressure cooking. Meanwhile, the unit of CVP levels is a spring valve pressure regulator and it makes cooking pressure much steadier when the pressure cooker is releasing steam. It makes this new pressure cooker a more closed system with little loss of moisture.
