Syncube Control Valves

DATA SHEET

ME-4140, ME-4240 and ME-4340
Spartan non-spring-return Syncube Actuators
Description
There are three different Syncube actuator models available.
ME-4140 three point floating,
ME-4240 PWM 0.25-5.0 sec,
ME-4340 modulating 0-10 or 2-10Vdc
They drive 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.
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
types, electronically controlled in PWM ME-4240 and modulating ME-4340
types. However, in all cases, 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
(see valve body specifications).
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.).

General Actuator Specifications

Installation Instructions
All Syncube ME-4140, ME-4240 and ME-4340 actuators can be installed on all
Spartan zone valves bodies which are designed for use on hot or chilled
water, up to 50% glycol mix, or for low-pressure steam.The commercial type
valve bodies all utilise low zinc anti-dezincification bronze coupled with
long life replaceable and inter-changeable internals from 0.15 to 9.0 Cv
(0.13 to 7.75 Kv’s). Refer to Control Valve Bodies Data Sheet.
The actuator can be installed vertically,
or at any angle not exceeding the horizontal.
The Actuator mounting thumbnut is to
be hand-tightened only, using tools
may result in over-tightening.

Thumbnut

Take note that the actuator should never be attached to the valve if its stem
has been electrically driven down for fear of damaging the operating
mechanism inside. Actuators shipped separately from the factory are always
delivered stem up.
