Valve Actuator | 40 in-lb | Non-Spring Return | 24V | Modulating

These compact but powerful direct-coupled actuators provide tri-state or proportional control for small dampers or valves in HVAC systems. A minimum torque of 40 (MEP-40xx) or 80 (MEP-48xx) inch-pounds is available over the 95° angular rotation.

The MEP-4002/4022/4802/4822 proportional actuator models accept a 0-10 or 2-10 volts DC control signal input from a thermostat, controller, or building automation system. “Anti-jitter” circuitry significantly reduces hunting and needless wear on the actuator and valve packing or damper components (from unnecessary miniscule position changes caused by undamped analog input signals). A user-initiated, auto-mapping feature provides better equipment control by reassigning the 0-10 or 2-10 volts DC input signal range over a reduced rotation range (from 45° to 95°). These models also feature a switch-selectable, 1–5 or 2–10 (or 0–5 or 0–10) VDC voltage feedback output that is proportional to the actuator position.

The MEP-4001/4003/4013/4021/4801/4813/4821 tri-state/two-position models are designed for use with floating thermostats, controllers, or building automation systems. The MEP-4013/4813 models feature a 10,000 ohm (+/- 10%), three-wire potentiometer feedback output. (The tri-state MEP-4003/4003V do not have two-position functionality or the larger green top enclosure.)

The MEP-4×21/4×22 models also have a fully adjustable, built-in SPDT auxiliary switch, for remote position indication or controller and equipment interface.

MEP-4001V/4002V/4003V actuators have brackets with a patented, quick-mounting mechanism that mounts directly on VFB-43…BC and VFB-46…BC series valve bodies (or VFB-43…BX and VFB-46…BX series with HPO-5074 kit). (See the “V” Models Valve Cross-Reference section in the data sheet for more information.)
All other MEP-4000s 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 feature allows manual positioning of the actuator.

For fail-safe versions of these actuators, see the MEP-4200/4500/4900 series. See also the modular MEP-4042/4842 and the fast-operating 10 in-lb. MEP-4101.
