SAMSON AG, founded in 1907 is a German control valve manufacturing company headquartered in Frankfurt. It develops systems and products that can control all types of fluid. [ 1 ] Its product line includes valves, self-operating regulators, automation systems, sensors, thermostats, and digital devices, among others.
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. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure , temperature , and liquid level.
The most common final control element in the process control industries is the control valve. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point.

However, some large valves are impossible to operate manually and some valves may be located in remote, toxic, or hostile environments that prevent manual operations in some conditions. As a safety feature, certain types of situations may require quicker operation than manual actuators can provide to close the valve.
Traditional control valves make it inevitable. As we size a control valve, the K v calculated almost certainly will not match the K v of the nearest appropriate valve. For example, a K v calculation of 4.5 m 3 /h would most likely lead to the selection of a valve with a K v = 6.3 m 3 /h. This means the valve is capable of delivering 40% more ...
Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of ...
