High flow/low flow valve with dual actuators
The patent US12044319B2 describes a high flow/low flow valve designed to manage fluid flow through a system effectively. The valve comprises a valve body with a fluid inlet and outlet connected by a passageway that includes both low flow and high flow valve seats. Each valve seat is paired with a corresponding valve plug—low flow and high flow—that regulates fluid flow. The design allows for independent positioning of the low flow and high flow valve plugs, enabling precise control over fluid dynamics. The patent specifies that the maximum low flow port fluid flow is between 5% and 25% of the maximum high flow port fluid flow, ensuring a clear distinction between the two flow rates.
Additionally, the patent outlines various configurations and components of the valve, including the option for different types of trims for high and low flow, such as clamped cages and skirt-guided plugs. The claims also detail methods for operating the valve, emphasizing the sequential positioning of the valve plugs to optimize fluid flow. For instance, the methods involve adjusting the high flow valve plug to a specific position before manipulating the low flow valve plug to maximize overall fluid flow. This innovative design and operational methodology aim to enhance the efficiency and versatility of fluid control in various applications.
