A wellhead choke valve is a pressure-control valve used to regulate the flow of oil, gas, and other well fluids from a well. It controls flow by restricting the passage through the choke, helping manage production rate and downstream pressure in high-pressure wellhead systems.
Selection depends on factors such as working pressure, valve size, process media, temperature, flow rate, choke type, material requirements, PSL, PR, and end connections. Working with experienced choke valve suppliers can help ensure the correct valve is selected for the wellhead application.
An adjustable choke valve allows the flow opening to be changed during operation, providing greater control over production flow. A positive choke valve uses a fixed or replaceable choke bean to provide a predetermined flow restriction. The appropriate type depends on the well's production and flow-control requirements.
