What is adjustable choke valve?
1. n. [Drilling] A valve usually used in well control operations to reduce the pressure of a fluid from high pressure in the closed wellbore to atmospheric pressure. It may be adjusted (opened or closed) to closely control the pressure drop.
How does a choke valve work?
By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally greater amount of fuel to be pushed from the main jet into the combustion chamber during cold-running operation.
What is bean size in choke valves?
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.
What is a fixed choke?
A fixed choke (also known as a positive choke) is a device that is used to control the flow of fluids by directing the flow through a fixed-size hole. The calibration on the choke allows for accurate control over the flow or predetermined fluid rates that have been arrived at in various test conditions.
What is positive choke valve?
The simplest configuration of the choke, which has a blanking plug assembly and flow bean in a standard choke body provides fixed flow conditions with respect to the various size of choke flow beans.
Does choke stay open or closed carburetor?
Normally choke will be in open position, in which valve is parallel to the air flow, and has no effect on the air flow. When choke is actuated by mechanical or by pneumatic method, it rotates an angle restrict the air flow (closed position).
What is a bean on a choke valve?
A choke bean is a fixed choke used to control fluid flow. The choke bean consists of a replaceable bean usually made of hardened steel. The choke bean is mounted near the Christmas tree, which is a set of valves and fittings at the top of a well to control production or flow.
What is an improved modified choke?
Improved Cylinder Choke. Modified choke has moderate constriction. The pellets stay together longer, making the shot string denser and more useful at longer ranges. This choke is used often when dove hunting and when using steel shot to hunt for ducks or geese.
What is surface choke?
In order to control the flow rate of the well at the surface, a surface choke can be installed to control the flow rate of the well. Although a choke device is used for a number of purposes at the surface or downhole, its principal use is to control flow rate and pressure of the produced hydrocarbon at the wellhead.
Does it hurt to run an engine with the choke on?
Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine.

What is the best choke for well control?
Within the adjustable style of choke, needle and seat trim is the most economical option for well control. Selected for applications with tight gas and oil and low-pressure production, needle and seat trim also has the lowest ability to control pressure and flow compared to other style trim designs.
What is the trim on a choke made of?
The heart of the choke is its trim. Our trim is constructed with Tungsten Carbide specially formulated to resist erosion even when under the most severe applications. We have the following geometries: Our history 1958 Best Industries introduces production chokes into the market.
