In the industrial sector, one of the most important fields of application of automation devices is found in the world of Electropneumatic Positioners also known as EP 6/10. This technology is used to adjust the valves of machines for gas, air, oil and other liquids that eventually serve as controlling elements. The principal components of an EP 6/10 include the following: a control unit, four valves, pumps, and electromagnetic amplifiers. Despite the complexity of its parts, the EP 6/10 can be understood in a few simple concepts.

The basics of EP 6/10U/O functioning are in the control valves. This is done by an electrical signal sent to the actuator, and when a force is applied, the motion of the valve will be transmit. The control unit, the core element of the machine, includes two functions that regulate the actuator and the pumps. The first one is the compressor, which is responsible for inflating and deflating the control valve, thus opening or closing the pipeline. The second one is the centrifugal pump which, thanks to its power, enables the opening and closing process of the valve’s orifice.

With an input signal, the control valve is activated; this can be done electromagnetically or pneumatically. The electromagnetic amplifier receives two signals: a) a connection evaluation of the valve positions so that the demanded position can be compared with the one existing and b) a compared confirmation of events by the control system. This enables the EP 6/10 to offer a clear indication of its result.

The EP 6/10 assembly has a number of applications depending on the industrial sector in which it is used, for instance:

• Controlling the injection of a determined volume of fluid in a pressure branch of an industrial pipe;
• Proportional control of the homogenization of two fluids in container mixes;
• Activation of a high pressure release of liquid for regulatory purposes;
• Proportional or constant control of air flow inside a pressurized area;
• Control of the flow in pressure or vacuum tubes;
• Accurate delivery of material such as oil or gas;
• Controlling the level of fluids in a tank.

Some of the advantages that the EP 6/10 provides are:

• Compliance with safety standards established by any industrial control authority;
• Reliable and durable, with no need for maintenance;
• high power and efficiency;
• Fast and precise control;
• Easy to install.

Finally, EP 6/10 units are important elements in hydraulic turbines, and so they are included in the assembly of these machines. They are used to adjust the speed at which the turbine will work; this is achieved through a proportional control of the valve’s travel. The EP 6/10 can also be used to indicate any damages in the turbine, and with the signals that this device transmits it is possible for the control system to make a reset or stop the motor in an eventuality like this. The speed at which the turbine rotates can be regulated with the help of the control unit; the signal that it transmits to the valve will cause it to open or close gradually.

In conclusion, the EP 6/10 is a powerful and reliable system that plays an important role in many industrial processes for controlling all sorts of fluid flow. The units are intuitive to install, and the programmed commands with the appropriate data are all that is needed for proper functioning. As stated before, the EP 6/10 units have several applications within industrial sites thanks to its precision and accuracy when handling both liquids and gases.
