Proportional valves

Proportional valves

ASCO Numatics proportional regulators adjust the pressure or flow rate in relation to an electrical signal. This category of products includes various control technologies to meet several adjustment needs.

Proportional valves for pressure control

Sentronic, Pulstronic and Servotronic are volumetric pressure regulators that act on an electrical control signal. This type of component is used in applications where rapid pressure variation is required. SentronicD allows the customization of the control circuit through the dedicated software, thus adjusting the valve according to the specific application specifications.

Proportional valves for flow control

Flowtronic and Piezotronic are volumetric flow regulators that adjust the flow quickly and precisely based on an electrical control signal. This type of component is designed for applications with rapid flow variations. In addition, FlowtronicD has a feature-rich software including customization of the control circuit so that the valve can be precisely adjusted on the application.

Digital controller for proportional solenoid valves

ControlD is a PID (Proportional-Integral-Derivative) controller that controls the current to a solenoid coil, making sure that any solenoid valve responds proportionally to an electrical control signal. The software of this controller includes, among other functions, diagnostics and customization of the control circuit.
