Samson AG
SAMSON Aktiengesellschaft, AG, founded in 1907 by Hermann Sandvoss, is a German corporation headquartered in Frankfurt. It develops systems and products that can control all types of fluid. Its product line includes valves, self-operating regulators, automation systems, sensors, thermostats, and digital devices, among others. Background SAMSON was founded in 1907 after Sandvoss invented a regulator that can function without an external power supply. The device automatically controls processes by utilizing differences in pressure. By 1916, its main manufacturing facility and headquarters were relocated to Frankfurt's River Main. Aside from regulators, SAMSON AG develops measurement and control technologies such as control valves, and electro-pneumatic transducers, control valves for HVAC systems - controllers and sensors for HVAC systems. The control valves have modular designs, giving it flexibility in terms of usage in engineering and building automation processes. The range of ...

Aktiengesellschaft
(; abbreviated AG, ) is a German word for a corporation limited by Share (finance), share ownership (i.e. one which is owned by its shareholders) whose shares may be traded on a stock market. The term is used in Germany, Austria, Switzerland (where it is equivalent to a ''S.A. (corporation), société anonyme'' or a ''società per azioni''), and South Tyrol for companies incorporated there. It is also used in Luxembourg (as lb, Aktiëgesellschaft, label=none, ), although the equivalent French language term ''S.A. (corporation), société anonyme'' is more common. In the United Kingdom, the equivalent term is public limited company, "PLC" and in the United States while the terms Incorporation (business), "incorporated" or "corporation" are typically used, technically the more precise equivalent term is "joint-stock company" (though note for the British term only a minority of public limited companies have their shares listed on stock exchanges). Meaning of the word The German w ...

HVAC
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and Sick building syndrome, healthy building conditions are regulated with respect to temperature and ...

Control Valve
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. In automatic control terminology, a control valve is termed a "final control element". Operation The opening or closing of automatic control valves is usually done by electrical, hydraulic or pneumatic actuators. Normally with a modulating valve, which can be set to any position between fully open and fully closed, valve positioners are used to ensure the valve attains the desired degree of opening. Air-actuated valves are commonly used because of their simplicity, as they only require a compressed air supply, whereas electrically operated valves require additional cabling and switch gear, and hydraulically actuated valves required high pressure supply and return lines for the hydraulic fluid. The p ...

Rotary Valve
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. The common stopcock is the simplest form of rotary valve. Rotary valves have been applied in numerous applications, including: * Changing the pitch of brass instruments. * Controlling the steam and exhaust ports of steam engines, most notably in the Corliss steam engine. * Periodically reversing the flow of air and fuel across the open hearth furnace. * Loading sample on chromatography columns. * Certain types of two-stroke and four-stroke engines. * Most hydraulic automotive power steering control valves. Use in brass instruments In the context of brass instruments, rotary valves are found on horns, trumpets, trombones, flugelhorns, and tubas. The cornet derived from the posthorn, by applying rotary valves to it in the 1820s in France. An alternative to a rotary valve trumpet wou ...

Globe Valve
A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. Globe valves are named for their spherical body shape with the two halves of the ''body'' being separated by an internal baffle. This has an opening that forms a ''seat'' onto which a movable ''plug'' can be screwed in to close (or shut) the valve. The plug is also called a ''disc''. In globe valves, the plug is connected to a ''stem'' which is operated by screw action using a handwheel in manual valves. Typically, automated globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly. Information Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term ''globe valve'' is still often used for valves that have such an interna ...

Chemical Industry
The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials (oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products. The plastics industry contains some overlap, as some chemical companies produce plastics as well as chemicals. Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians. History Although chemicals were made and used throughout history, the birth of the heavy chemical industry (production of chemicals in large quantities for a variety of uses) coincided with the beginnings of the Industrial Revolution. Industrial Revolution One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736 pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine with water ...
