Series 1900 5.12 Functional diagram CLOSED LOOP scheme (internal control circuit) The proportional regulator is defined as CLOSED LOOP because a pressure transducer in the circuit transmits a continuous analog signal to the microprocessor that compares the reference value with the one that is detected and behaves accordingly, supplying the control solenoid valves in the correct way.

In the specific case of a pneumatic cylinder, it has to act on parameters that determine the force generated and the speed at which the valve stemmoves. The same holds true for a rotary actuator where we do not speak of force but rather the application of torque. These parameters often have to be modified dynamically during operation of the the machine on which they are installed. Traditional solutions that make use of the pneumatic logic associated with use of valves supplied at different pressures often need to be large in size. It was from this requirement that the alternative solution of using a regulator came about, since it can change the pressure value over time. This type of regulator is called an electronically controlled proportional regulator. There are 3 sizes with flow rates of 7; 1,100; and 4,000 Nl/min.The model that manages the positive pressure controling a vacuumgenerator was then added to this range. Field of application Fields of application for proportional regulators are any where it is necessary to dynamically control the force of an actuator, variation of pressure or degree of vacuum. Some examples: locking systems, painting systems, tensioning systems, packaging machinery, pneumatic control braking systems, force control for welding clamps, thickness compensating systems, balancing systems, laser cutting, pressure transducers to control modulating valves, test benches for testing systems, controlling the force of air gauges in sanding systems, management of force exerted by suction cups in handling applications. Product description The pneumatic connections of the regulator require the aperture for supply and discharge to be on one side and the aperture for use on the opposite side. On the other two remaining sides there are apertures of G1/8" that are plugged up with removable plugs, however it is possible to connect a pressure gauge through them or use the connections as outputs. On the side where the service connection is, there is an M5 aperture where you can connect the return vacuum signal (to the pressure transducer).This option makes it possible to pick up the signal from a remote point rather than directly from the service connection. In the upper part of tregulators there are control solenoid valves, the pressure sensor and the electronics forcontrol. The part for electronically controlling the regulators is the same for all the 3 sizes. The new range of proportional regulators is supplied as standard with all the functionality initially considered only as optional; the only selections necessary in the ordering phase are thus related to the type of signal for control of voltage(T) or current (C) and the range of working pressures.
