No, it is not recommended to use the same weight for pressure cookers of different capacities, even if they are of the same make. The weight or pressure regulator on a pressure cooker is designed to control and maintain a specific pressure inside the cooker during the cooking process. Different pressure cookers have different capacities and sizes, which affects the amount of steam generated and the pressure required for proper cooking.
The weight or pressure regulator is calibrated to release steam at a specific pressure level, typically measured in pounds per square inch (psi). Using the wrong weight for a pressure cooker can result in inaccurate pressure readings, which may lead to undercooked or overcooked food.
Each pressure cooker model and capacity is designed with specific weight settings to ensure proper pressure control. These weights are usually provided by the manufacturer and are specific to the model and capacity of the pressure cooker. It's important to use the correct weight provided with your pressure cooker or follow the manufacturer's instructions for selecting the appropriate weight based on the cooker's capacity.
Using the wrong weight can compromise the safety and functionality of the pressure cooker, so it's best to always use the weight that corresponds to the specific cooker you are using.
