MEP-4252V | Valve Actuator | 25 in-lb | Electronic Fail-Safe | 24V | Modulating | KMC Controls

KMC Controls 24v 25in# 2-10vdc SR Actuator (MEP-4252V) is designed to provide precise and reliable motion control in industrial and automation applications. This 24-volt actuator features a 25-inch stroke length, providing ample movement range for a variety of tasks. Its 2-10 VDC control signal enables precise positioning and speed control. The MEP-4252V actuator incorporates a durable construction, ensuring longevity in challenging operating environments. Its compact design allows for easy integration into tight spaces. This actuator is engineered for use in various applications, including automated machinery, robotics, and material handling systems.

These compact but powerful direct-coupled ControlSet actuators provide two-position, tri-state, or proportional control for dampers or valves in HVAC systems. Efficient, durable, capacitor-driven fail-safe with switch-selectable direction provides consistent torque in both powered and fail-safe modes. A patented noise reducer provides whisper-quiet operation in both modes. A minimum torque of 25 (MEP-42xx), 45 (MEP-45xx), or 90 (MEP-49xx) in-lb. is available over the 95° angular rotation.

MEP-4xx2 proportional models accept either a 0–10 or 2–10 VDC control signal input from a thermostat, controller, or building automation system. “Anti-jitter” circuitry significantly reduces hunting and needless wear (from unnecessary miniscule position changes caused by undamped analog input signals) on the actuator, valve, or damper components. A user-initiated, auto-mapping feature provides more precise equipment control by reassigning the input signal range over a reduced rotation range. These models also feature a switch-selectable, 0–5 or 0–10 (or 1–5 or 2–10) VDC voltage feedback output that is proportional to the actuator position. (MEP-4252 shown in photo.)

MEP-4xx1 tri-state/two-position models are designed for use with floating thermostats, controllers, or building automation systems. MEP-4xx4/4xx5 two-position models are available in 24 VAC/VDC or 100-240 VAC models.

MEP-4x7x models also have one fully adjustable, built-in SPDT auxiliary switch for remote position indication or equipment interface. MEP-497x models include a second fixed switch at 10° from full CW direction. A three-foot cable is included with the switch(es).

MEP-4xxxV actuators have brackets with a patented, quick-mounting mechanism that mounts directly on VFB-43…BC and VFB-46…BC series valve bodies.

All actuators mount directly to 1/4- to 5/8-inch (6 to 16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm) square shafts, eliminating the need for expensive and complicated linkages. A non-rotation bracket, to prevent lateral movement, is included with each actuator. A gear disengagement button allows easy manual positioning of the actuator.

(For similar actuators without fail-safe, see the MEP-4201/4501/4901 and the MEP-4000/4800 series. If higher torque is required, see the MEP-7500/7800 series.)
