The integration of control valves into the DCS technology determines the accuracy of the control loop and greatly affects the cost and quality of the final product. This integration is a prerequisite for effective preventative maintenance of control valves and also adds to the availability of the system.

A milestone in the integration of the field equipment and the control room systems is the SAMSON smart positioner (picture on the top right). These devices enable communication and troubleshooting during operation via the HART®, PROFIBUS or FOUNDATION™ fieldbus protocols.

The SAMSON product line also includes limit switches which issue signals when a predetermined value is reached, solenoid valves which automatically override the valve to a pre-determined position (picture on the bottom right), or lockup valves which hold the valve in its last position in case of an energy failure.

Volume amplifiers boost the input signal of positioners. A broad range of service units provides high quality supply air.

SAMSON is a world leader in this important field. SAMSON figured among the first companies to introduce the digital communication positioner to the marketplace. By taking an active role in combining practical applications and university research, SAMSON has remained at the forefront of this technology.

Positioner Highlights

One of the basic principles of our highly developed civilization is reliable and inexpensive distribution of energy and, at the same time, the responsible and wise use of resources. For decades, self-operated regulators, which do not require auxiliary power to operate, have been used on air, steam and various other heating media in local and industrial energy distribution applications.

SAMSON's self-operated regulators are of modular design. They are easy to assemble and service, reducing costs significantly. In addition, greater safety is achieved, as they continue to work reliably in the event of a power failure.

To fulfill unique applications to the customer's satisfaction, SAMSON has combined an electrically operated control valve and a self-operated regulator in one body to provide the ultimate solution.

New areas of development, such as thermostatic regulators with hydraulic actuation, generate savings by allowing the use of low volume heat exchangers to produce hot water without compromising comfort.

Pressure regulators for millibar ranges reliably control inert gases in reaction and storage tanks containing oxidation-sensitive, toxic or explosive substances, thereby protecting the environment.

SAMSON regards its success as a stepping stone in the quest for even better and more innovative solutions. This is reflected in SAMSON's commitment to manufacture the highest quality product possible.

Many tasks which used to be performed on site are now carried out on the monitor in the control room. Complex operations and processes demand quick reactions. As a result, maximum plant safety and process visualization are essential. In today's fast-paced environment, user-friendly equipment, compact work stations and standardized communication systems are indispensable.

SAMSON's answer to these challenges is: "TROVIS". Using TROVIS equipment, new ideas can be realized in process engineering as well as in the automation of plants and buildings. Simple compact controllers as well as modular systems using standardized communication systems offer solutions to any automation problem in process engineering.

TROVIS equipment and systems by SAMSON are used successfully in a wide range of industries, for example, food and beverage, pharmaceutical, waste management, and other automation and control systems.

For the HVAC industry, the main considerations are economy and energy savings without compromising comfort.

All automation tasks in building management as well as large district heating systems can be solved efficiently and conveniently with the user-friendly TROVIS equipment.

Responsible for the complete automation systems, individual projects and turnkey installations is SAMSOMATIC, a subsidiary of SAMSON.
