Alfa Laval manufactures valves, pumps, heat exchangers, evaporators, distillers, oil separators, filters, ballast water treatment systems, and all other hardware vital to the operation of the a ship's engine room. As of 2011, Alfa Laval consolidated its Marine, Offshore, and Diesel divisions into one, Marine & Diesel, division in an effort to ...
A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy .

In 1991 Alfa-Laval was bought by Tetra Pak. In 1993 the division which produced dairy and farming machinery was split from Alfa Laval and named Alfa Laval Agri. Both companies became part of the Tetra Laval Group. In 2000 the Tetra Laval Group sold Alfa Laval, while Alfa Laval Agri was kept and renamed DeLaval after the company's founder.
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)
Ordinary valves can have many ports and fluid paths. A 2-way valve, for example, has 2 ports; if the valve is open, then the two ports are connected and fluid may flow between the ports; if the valve is closed, then ports are isolated. If the valve is open when the solenoid is not energized, then the valve is termed normally open (N.O.).
A rotary valve (also called rotary-motion valve) is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes. [1] The common stopcock is the simplest form of rotary valve. Rotary valves have been applied in numerous applications, including:
A full bore (sometimes full port) ball valve has an oversized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines that require pigging .
