M/P Converters

M/P Converters

Motor-driven pneumatic regulators, or motor-to-pressure (M/P) converters, are control devices that translate an electrical motor input into a proportional pneumatic output. The motor adjusts the regulator’s setpoint through mechanical linkage, enabling accurate modulation of downstream air or gas pressure. This integration of electrical actuation with pneumatic regulation allows precise, repeatable control without the need for manual adjustment, making them ideal for processes that demand consistent and reliable pressure settings.

These regulators are useful as they provide a direct interface between electrical control systems and pneumatic equipment, eliminating the need for intermediary signal converters. Their motor-driven design enables fine resolution in setpoint changes and maintains stable pressure output even under fluctuating supply or demand conditions. By combining electrical precision with pneumatic reliability, they help reduce process variability, improve efficiency, and enhance product quality across a wide range of applications.

In industrial environments, motor-driven pneumatic regulators excel in scenarios where remote or automated control is essential. They are commonly integrated into systems requiring safe operation in hazardous areas, where explosion-proof motor designs allow for pressure control in flammable atmospheres. Their robust construction and compatibility with various gases make them suitable for demanding conditions, from heavy manufacturing to chemical processing.

Typical applications include controlling air supply to pneumatic actuators, modulating pressure in instrument air systems, adjusting gas delivery in process control loops, and regulating pressure in packaging, coating, or forming machinery. They are also used in laboratories, energy production facilities, and other operations where precise, automated, and reliable pressure regulation directly impacts safety, performance, and output quality.
