Spartan Syncube Zone Valve Electric Actuator 2-10VDC Non-Spring Return Modulating 24V

Spartan ME4240 24V Non-Spring-Return Syncube Actuator Modulating
Drives 2-, 3- and 4-port control valves with a unique, patented, non-springreturn
movement having five robust moving parts. Without small toothed, high pitched gears to wear out or whine, the compact movement has a life expectancy in excess of 500,000 cycles (1,000,000 strokes) or 1,500,000 corrections. The reversible, brushless, synchronous, electric motor maintains accurate positioning and provides creep-free control with extreme accuracy.
All of the actuators ride high and clear of pipes, insulation (lagging) and heat, yet the overall height above the actuator remains low.
General Features:
The maximum stem output is force-balance controlled in floating ME-4140.
valve stem force is enough to maintain and control
high differential pressures to at least 60 psig (4.0 Bar) or more, except on steam. A blue/semi-clear case or an opaque cream white case are both available, the former allowing viewing of the moving parts, the latter not. (check with your distributor to ascertain which is kept in local stock). In both cases, a top mounted position indicator is available for viewing or for feeling its rise and fall
(useful in dark, cramped places such as ceiling spaces and/or inside fan coil cabinets, etc.).
