About FC140 Choke Bean or OCT Type Positive Choke Bean with lined Tungsten Carbide

Product Overview

The FC140 Choke Bean is a precision-engineered positive choke bean designed for accurate flow control in oil and gas wellhead equipment. Also known as the OCT FC140 choke bean, this component is widely used in positive choke valves to regulate the flow of fluids from wellheads, production trees, choke manifolds, and well testing equipment.

As a critical valve trim component, the choke bean is installed in the choke body to control flow rate, reduce pressure, and enable accurate calculation of oil and gas production volumes.- Each bean features a fixed-size precision orifice, allowing operators to calculate flow rates based on the specific orifice diameter selected.

FC140 is the industry-standard trim for 2-inch positive chokes, while the H2 style is standard for 3-inch chokes.--11 Our FC140 choke beans are 100% interchangeable with major OEM designs including OCT, Cameron, Gray Tool, and other industry-standard equipment.

Key Features

1) Premium tungsten carbide lining - Exceptional resistance to abrasive wear from sand and solid particles in production fluids.

2) Superior corrosion resistance - Suitable for HS and CO environments (sour service).

3 Precision-ground orifice - Available in 1/64-inch increments for accurate, repeatable flow control.

4) High strength and rigidity - Withstands extreme pressure differentials.

5 Heat treated for durability - Hardness 207-235 BHN for extended service life.

6) Excellent erosion resistance - Resists erosion caused by high-velocity fluids-32.

7) 100% interchangeable Compatible with OCT - Cameron, Gray Tool, and industry-standard chokes.
