For liquid gases, Samson valves are in control

Keeping magnets cool to see microscopic structures
Meeting the challenge of controlling very high flow rates, using very high accuracy control of DP, were among the key factors in a recent successful 'cooling' application for Samson Control Valves
Thanks to its low steam pressure even at high temperatures, plants can be implemented with low pressure ratings.
As a result, the investment compared to steam networks is relatively small.
However, it must be ensured that the heat transfer oil circulates permanently.

Fast and precise control of large valves
Samson controls have introduced a new positioner package for exact valve positioning, with fast response times over the entire operating range, even for large control valves
Otherwise, the plant is exposed to overheating and cracking, which can have severe consequences.
A Samson Type 42-25 Differential Pressure Regulator installed in the bypass line of the heating circuit makes sure that the required minimum flow rate is achieved and that the heat transfer oil does not overheat.
Thus, your plant will operate reliably at the optimum temperature.
These units are in use in many plants, including several involved in fish processing and the timber industry.
Manufacturing products that meet the highest quality standards calls for production plants whose components comply with the most stringent requirements as well.
At M+W Zander, Type 45-2 Differential Pressure Regulators with threaded ends are integrated into plants designed for the conditioning of pure air in semi-conductor chip production.
To guarantee the best possible operating conditions for temperature control valves used in cooling, the differential pressure across the temperature control valve must be regulated.
An easy application for the Samson Type 45-2.
Automotive Robots.
The welding guns of robots, used for example at VW, are cooled with the help of almost 500 Samson flow and differential pressure regulators.
This cooling is necessary to prevent the guns from overheating due to the high duty cycles of the welding robots.
The flow of the cooling medium is controlled over solenoid valves that can close only against low differential pressures.
Samson Type 46-7 Flow and Differential Pressure Regulators make sure that no excessive differential pressures occur and that each welding gun is assigned the proper amount of coolant.
Of course the Samson regulators are entirely free of substances that are not compatible with paint, as is essential in the automotive industry.
