Choke bean is often used in the positive choke valve for controlling the flow, is same as Cameron type H2 big john choke bean, body Material: 410SS, lined with Tungsten Carbide (C10 or C25) or ceramic, to protect them from corrosive and abrasive wear. 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 graduations 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.

Product Features:

Positive choke Bean used to control the flow of fluids and is usually mounted on or close to the Christmas tree, High pressure gas/oil, with abrasive sand minerals passes through these chokes at high speed causing rapid wear. Bean chokes contain a replaceable insert, or bean, made from hardened steel /ceramic or stainless steel/ tungsten carbide or similar durable material. Combustion and control chokes are lined with a high hardness, abrasion and corrosion resistant 98.5% alumina or tungsten carbide liners to protect them from corrosive and abrasive wear
