A choke may also include a conical valve and valve seat, to ensure complete shutoff. Fluids flowing into the cage (through all uncovered holes) enter from all sides, producing fluid jets. The jets collide at the center of the cage cylinder, dissipating most of their energy through fluid impinging on fluid, producing less friction and cavitation ...
In oil and gas production a choke manifold is used to lower the pressure from the well head. It consist of a set of high pressure valves and at least two chokes. These chokes can be fixed or adjustable or a mix of both. The redundancy is needed so that if one choke has to be taken out of service, the flow can be directed through another one.
The company's products include blowout preventers, control systems, riser string packages, choke valves, riser tensioners, and drill string compensators. History
Choke valve, Butterfly valve used to limit air intake in internal combustion engine. (Not to be confused with choke valves used in industrial flow control, above.) Clapper valve: a type of check valve used in the Siamese fire appliance to allow only one hose to be connected instead of two (the clapper valve blocks the other side from leaking out)

The Straight-Eight engine was announced by The Daimler Company Limited on 1 May 1934 with its first vehicle, Daimler's new Twenty-Five saloon and limousine. The new engine was the first of a series intended to replace Daimler's outmoded large sleeve-valve six-cylinder and twelve-cylinder engines.
A tree often provides numerous additional functions including chemical injection points, well intervention means, pressure relief means, monitoring points (such as pressure, temperature, corrosion, erosion, sand detection, flow rate, flow composition, valve and choke valve position feedback), and connection points for devices such as down hole ...
If the fluid is a liquid, a different type of limiting condition (also known as choked flow) occurs when the venturi effect acting on the liquid flow through the restriction causes a decrease of the liquid pressure beyond the restriction to below that of the liquid's vapor pressure at the prevailing liquid temperature.
