KMC Controls MEP-3511 Actuator

The KMC Controls MEP-3511 Actuator is a direct-drive, non-spring return actuator designed for modulating control in commercial HVAC systems. As the engineered MEP-3011 replacement, this 2/10VDC valve actuator provides high-torque performance for normally closed (N/C) valve applications. It operates on a standard 24VAC power supply and accepts a proportional 2-10VDC control signal, ensuring precise positioning and reliable air or water flow regulation. Built for long-term service in building automation systems (BAS), the MEP-3511 features a brushless DC motor and a compact footprint that simplifies field installation in tight mechanical spaces. This unit is specifically designed for VEZ series zone valves and other compatible HVAC pressure-independent valves. By utilizing advanced gear-train technology, this electric control valve actuator maintains stable operation without the drift common in older pneumatic or floating-point models, making it a critical component for maintaining strict environmental setpoints in modern facility management.

• Direct Compatibility: Seamlessly replaces legacy MEP-3011 units without requiring extensive rewiring or mounting modifications.
• Precise Modulation: Responds accurately to 2-10VDC signals for fine-tuned control of normally closed valve assemblies.
• High Reliability: Features a non-spring return design to eliminate mechanical fatigue points in non-failsafe applications.
• Efficient Integration: Optimized for use with KMC Controls controllers and standard 24VAC HVAC power circuits.

Common Questions & Technical Support Is the MEP-3511 a drop-in replacement for the MEP-3011? Yes, the MEP-3511 is the official updated version of the MEP-3011. It shares the same electrical specifications?Çöoperating on 2-10VDC?Çöand is designed to fit the same valve mounting brackets, ensuring a straightforward swap for service technicians. What happens if the 24VAC power is lost? Because this is a non-spring return actuator, the device will remain in its last commanded position upon power loss. For applications requiring a failsafe "closed" or "open" position during power outages, a spring-return model would be required. Can I use a 4-20mA signal with this actuator? The MEP-3511 is natively designed for 2-10VDC proportional signals. To use a 4-20mA signal, a 500-ohm resistor must be installed across the input terminals to convert the current signal to the appropriate voltage range.
