M2CP Electric Valve Actuators
M2CP Electric Valve ActuatorsThe strength of ductile iron with the agility of digital control.
2It’s Already Proven.A Heritage of PerformanceReliabilityBuilt on Proven TechnologiesM2CP actuators were introduced in 1979 as the Series 2000electric valve actuator. Since that time, the model has addedincreasingly sophisticated control capabilities—but retained allthe mechanical strengths that have established its threedecade record of reliability. As a result, many parts can interchange across the entire M2CP/Series 2000 range, andupgrades are remarkably easy to retrofit.The robust mechanical design of the M2CP is evident in its ductile iron gear case, bronze worm gear, and heat-treated alloyCurrent M2CP units evolved from proven technology—as shownby this EIM actuator, still operating after more than 50 years at awater distribution and storage system in New York City.steel worm. Add the flexibility of modular control packages,plus an international sales & support network, and the result isan actuator to count on for the long term.While the name has changed from Series 2000 to M2CP, EIM’suncompromising design and manufacturing standards haveremained constant. These robust units are part of the samefamily of actuators that have proven themselves again andagain across a wide range of applications in the world’s mostdemanding environments.Actuators in gas compressor stations must operate underconstant vibration.

8Design FeaturesMotors and Spur GearsEIM motors employ a minimum number of mounting configurations to maximize interchangeability. The motor and spur gear setform a modular unit that is mounted with only eight accessible fasteners.Motor gear assembly Wide range of motor-reduction spur gear selections offers multiple speed and torque output combinations. Field modification of torque and RPM outputs is easily accomplished.Motor gearsThermal overload protection Alloy steel motor gears are spline mounted for strength and easeof installation. Gear sets are interchangeable. Assembled in single- or double-reduction ratios as required foractuating time. Thermal contacts sense winding temperature and break thecontrol circuit before damage occurs. Standard motors, supplied with thermal overload protectionmay be disabled for emergency shutdown installations.CAUTION: disabling overload protection can undermineexplosion-proof capabilities and may violate hazardous codecertifications.
9Handwheel Override / Clutch MechanismM2CP actuators include an auxiliary clutch handle for emergency use. The clutch operates on the low torque side of the wormand worm gear drive train, and requires minimal force to operate. The valve, gate or damper is never disconnected from the selflocking worm gear.Clutch lever assemblyClutch spoolPadlockable clutch handle L ever shifts position of the splined clutchspool so power drive can be engaged byeither motor or hand wheel. A ssembly requires no adjustment andmounts with just three screws. L ever can be padlocked in “manual”mode for safe maintenance, or in“motor” mode to prevent tampering.Motor preference is standard. Common to all M2CP model sizes. Steel clutch spool makes simultaneousengagement of motor and handwheelimpossible. P o w e r f r o m m o t o r c a n n o t b etransmitted to manual lever. Drive connection to worm shaft is bysliding spline. Fused motor does not prevent handwheel operation. For added safety, clutch handle can bepadlocked in either manual or motorposition to prevent tampering orunauthorized use.1(Above: clutch handle detail)545236Clutch assembly1.

10Main Drive GearsThe main drive train of the M2CP actuator incorporates a heat-treated alloy steel worm, as well as a cast-bronze worm gear drivesleeve, supported by tapered roller bearings to maximize thrust load support.Worm and clutch assemblyClutch shaft splined connection Torque is received through clutch shaft from motor and firststage motor spur gear set. Torque springs are easily accessible for field changeover to raiseor lower torque range. Alloy steel, heat-treated worm is bearing supported. In operation, the clutch shaft is “fixed” by splined connection foraccurate geared limit drive calibration. Worm moves axially on its splined connection in either directionagainst the torque spring assembly for torque sensing. Input from motor and motor gears is transmitted through theworm to the bronze worm gear drive sleeve.Clutch shaft bearingGeared limit driveassemblyClutchGeared limit drivepinionWorm shaftassemblyTapered roller thrustbearings (top andbottom)Worm gear drivesleeve (bronze)Worm shaft bearingsTorque springassemblyBearing cartridgeTorque limit driveassembly
Torque-limit and Geared-limitDrive AssembliesLimit switch gearboxSplined drive bushing A limit switch gearbox is mechanically connected to actuatorworm through the geared limit-drive assembly. The limit switch gearbox remains in sync with valve position atall times, whether driven by motor or handwheel, even under lostpower conditions. B oth the torque and limit switches maintain settings in allconditions without relying on battery backup. Q uarter-turn actuators offer a bottom-entry splined steelbushing design to simplify mounting on valves. Splines provide high-strength, multiple-position connection tothe keyed valve shaft, improving accuracy of seat calibration andallowing for multiple mounting positions not possible with boredand keywayed drive sleeves. Cast bronze worm gear drive sleeves are mounted in high-qualitytapered roller bearings to maximize thrust load support.Torque switch Simple torque adjustments can be made to increase or decreasetorque caused by changes in operating conditions. Torque switch adjustment determines amount of movementpermitted before the motor reversing starter is de-energized. Mechanical torque sensing at final actuator output is notdependent on electronics. Open and close torque settings are independently adjustable. Torque switch can be pinned at any setting from 1 to 9 to limitmaximum actuator torque. Torque switch dial is active during power and handwheeloperation—no batteries required.Drive assembly cutaway view11
12M2CP Modular Control PackageUnsurpassed quality, reliability, flexibility, and ease of use.EIM changed the name of the Series 2000 actuator to M2CP to emphasize the advanced modular control package (which is alsoknown as M2CP) that serves each actuator. The M2CP module is designed to provide years of flexible, reliable, and cost-effectivevalve automation. Servicing and upgrading are quick and easy. The entire package or any component can be removed and replacedin minutes—ensuring that the M2CP actuator is always ready to accommodate future control technologies.EIM also continues to support the previous generation of technology, the MCP, which was the industry’s first modular controlpackage. (Some MCP units are still in service after more than 30 years.)M2CP offers ease of service and maintenance.Terminal board moduleThe entire electronic control package of the user-friendly M2CPcan be removed, assembled, disassembled, and replaced usingonly a standard screwdriver. As a result, field service can be performed quickly and easily with fewer mistakes. The module canalso be used for non-integral applications with remote-locatedmotor starters. Each transformer secondary is individually fused and groundedon the terminal board module for easy accessibility. Transient power surge suppressors are located throughout theM2CP module to protect electrical components. Terminal board module provides convenient access to 48terminal points, analog and digital signal inputs/outputs, andcontrol voltage.Reversing contactor Reversing contactor/power module is DIN rail mounted for snapin/snap-out convenience. Captive stainless screws securemodule from vibration. Reversing contactor is mechanically and electrically interlocked. Power module offers easy access to transformer primary fuses andseparate high-voltage terminal strip for incoming power leads. Optional phase sentry provides single-phase protection andprevents incorrect rotation.Integral control panel High-intensity LED panel lights offer lifetime service, much longerthan conventional incandescent bulbs. Triple O-ring sealed, stainless steel pushbuttons insure long-termintegrity against leaks and corrosion. 3-position selector switch is available with padlockable or keyswitch.Reversing contactorand primary fusesTerminal board module and secondary fusesModular control package with optional control boards
Options and Accessories13Mechanical Dial Position Indicator (MDPI)Futronic analog modulating control module Indicator is driven by a high-precision set of reduction gears. Onmulti-turn applications, visual indication of valve position from0-100% is provided. Dial is mechanically in sync with valve position at all timesregardless of motor/handwheel operation or availability of power. An optional combination mechanical/electronic position indicatoris also available (shown above). Tempered, explosionproof glass display window never becomesclouded or discolored. Futronic modulating controls are capable of handling bothposition and process control elements via industry standard 4-20mA signal. Futronic II position control uses 1- or 3-phase power. Futronic III process control uses 1-phase power, DC motor, solidstate starter. Futronic IV process control uses solid-state reversing starter, 3-phasepower, and AC motor. Futuronic VIII supports variable-frequency control.External door interlocks require an integral circuit breaker/disconnect to be engaged before opening electricalcompartment.Circuit breaker module The circuit breaker/disconnect switch interrupts the circuitbetween actuator and current source, removing all power toensure safety during servicing or field maintenance. Protects motor control apparatus and motor against over-currentdue to short circuits or grounds. Several disconnect devices are available mounted in electricalcompartment or in separate control modules that can be closecouple-connected to actuator or bracket-mounted to a wall,panel, rack, or pipe.Optionalremote control station(PBM)
