For example, if a pressure-reducing control loop is closely followed in the process by a flow control loop, the two control loops can appear to be fighting each other, causing both loops to oscillate.

This entire sequence of operation forms a loop through the transmitter and receiver and is referred to as flow control loop. The flow control loop and its components are shown in Figure 9. Figure 9: ...

Control valves are used to manipulate flows in most control loops. Control valve selection and specification is critical to ...

Many applications will work with on-off, closed-loop control using an analog sensor measuring temperature, pressure, level, or flow as an input to control a discrete output. The same analog sensors ...

Festo introduces the VTEP, the world’s first proportional valve terminal. The VTEP is an ideal solution for flexible gripping ...

Festo introduces its Controlled Pneumatics technology which features digital closed-loop control for applications ranging from welding and gripping to dispensing and pumping.
