Schneider Electric MS51-7203 Valve Actuator

The MS51-7203 Valve Actuator from Schneider Electric is a high-precision electric valve actuator designed for reliable globe valve control. This modulating, proportional, linear actuator provides smooth, repeatable flow control with spring-return operation and a compact NEMA 2 enclosure built for HVAC and process applications.

Operating on 24V AC (20–30V DC), it draws 0.28 A with running power of 7.4 W and 2.9 W in hold. The actuator supports 50/60 Hz service, delivers a nominal 220 lb force, and is compatible with control signals from 2–10 V DC or 4–20 mA DC. Its polymer body, 10-5/8 in W × 2-9/16 in D × 7 in H, and a 3 ft appliance cable supply installation flexibility in restricted spaces. Temperature tolerance from -22 to 140°F expands its suitability across demanding environments. Approvals include UL (Canada and US), UL, CUL, CE, and C-Tick for safe operation.
