Choke beans are commonly used in positive choke valves to control flow and are usually installed on or near wellhead equipment. High pressure gas/oil and abrasive sand minerals pass through these choke valves at high velocity, causing rapid wear. A bean choke consists of a replaceable insert, or bean, made of hardened steel or similar durable material.
