![Schneider Electric MS51-7103-100 Valve Actuator — New England Supply House spec card [NESH-SPEC-CARD-V2]](http://newenglandsupplyhouse.com/cdn/shop/files/spec-9033007562974.png?v=1782848071&width=1445)
Schneider Electric MS51-7103-100 Valve Actuator delivers precise modulating, proportional control for globe valves. This electric, linear actuator uses spring-return operation to provide fail-safe performance in HVAC and process systems. Designed for versatile power options, it operates on 24 Volt AC or 20–30 Volt DC, with a nominal 0.14 A current and 4.2 W running power (1.5 W holding). The polymer body is built for durability, with a NEMA 2 enclosure and a compact footprint (approximately 6-49/64 in W x 3-1/2 in D x 6-5/16 in H). It accepts a 2–10 V DC control signal and delivers a robust 105 N of nominal force to modulate globe valves smoothly. Approved to UL, UL Canada/US, CUL, CE, and C-Tick, this actuator is ideal for commercial and industrial applications requiring electric, proportional, and linear valve actuation. Whether retrofitting existing systems or designing new controls, it pairs easily with standard 2–10 VDC signals across industries.
