MODULATOR MOTOR
Key Info
| Infinite Position Control (Proportional Accuracy) | : | Unlike basic actuators that only open or close, modulating motors provide step-less adjustment. This allows for exact regulation of burner firing rates or steam valve positions, maintaining consistent temperature and pressure levels without the mechanical stress of constant cycling. |
| Universal Signal Compatibility | : | Modern units (like the Series 72) are compatible with standard electronic controllers using 4–20mA or 2–10VDC inputs, while legacy systems (Series 90) utilize 135-ohm potentiometers. This versatility makes them suitable for both new installations and retrofitting older boiler panels. |
| Fail-Safe Safety Systems (Spring Return) | : | Safety is critical in industrial combustion. Many modulating motors come equipped with a Spring Return feature. In the event of a power failure, the motor automatically forces the valve or damper to a "safe" default position (usually fully closed) to prevent overheating or fuel leaks. |
| Rugged Industrial Durability | : | Designed for harsh environments, these motors feature high-torque outputs and die-cast aluminum housings. They are engineered to operate reliably under the high-temperature conditions often found in boiler rooms and industrial processing plants. |
