Choke bean is often used in the positive choke valve for controlling the flow, our positive choke beans are similar as Cameron type H2 big john, body material: 410SS, lined with Tungsten Carbide or ceramic.
On one side of the choke manifold, calibrated choke beans are used to control flow rate through the fixed choke box. Each bean is a specific diameter, usually in increments of 1/64-inch, and is screwed into the choke box. These are the most common sizes (in inches) of choke beans used: 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 3/4, 7/8, 1, 1-1/4, and 1-1/2. Depending on the type of equipment used, the size of the choke bean can be as large as 3 inches.
