RCEL-100 Electric Actuator 1-Ph 230V ALS

RCEL-100 Remote Control Electric Actuator (1-Phase, 230VAC, ALS) – New

The RCEL-100 1-ph 230V ALS is a quarter-turn electric valve actuator manufactured by Remote Control (part of the Rotork group). Designed for high-duty marine and industrial process isolation, this unit provides robust electromechanical torque output to drive ball, butterfly, plug valves, and damper systems.

This specific configuration operates on 1-phase 230VAC (50/60 Hz) power and comes factory-equipped with the ALS (Auxiliary Limit Switch) package, providing supplementary dry contacts for remote telemetry, PLC/DCS confirmation, and interlocking safety loops. Constructed with a hard-anodized, epoxy-coated aluminum housing rated to IP67/NEMA 4 & 4X, this actuator resists harsh salt-spray, marine engine room heat, and outdoor corrosive washdowns.

Technical Specifications

Key Features

1. Irreversible Worm Gear Drive: Rolled steel worm coupled to an aluminum bronze wormwheel provides self-locking operation, preventing valve backdrive from hydraulic line hammer without separate electromechanical brakes.
2. Factory ALS Auxiliary Switch Package: Integrated SPDT mechanical switches (rated up to 250VAC 16A) provide independent open/close position feedback direct to automation panels or SCADA systems.
3. Integral Anti-Condensation Heater: Built-in internal ceramic PTC space heater (20W) runs continuously to eliminate moisture accumulation and terminal corrosion in fluctuating ambient environments.
4. Manual Override with Auto-Declutch: Heavy-duty external handwheel and manual declutching lever for emergency manual stroking; the drive gear automatically disengages manual mode and re-engages motor drive as soon as power is restored.
5. Severe-Service Environmental Sealing: Hard-anodized marine-grade aluminum housing with internal and external electrostatically applied epoxy-polyester powder finish, fully O-ring sealed to IP67 and NEMA 4/4X/6 standards.

Applications

• Marine Ballast & Bilge Automation: Remote valve operations for ballast tank stripping, sea chest isolation, and bilge manifold switching in machinery spaces.
• Shipboard Cooling & Fuel Treatment: Seawater main cooling circuits, low-sulfur MGO/HFO fuel changeover three-way manifold control, and lube oil purifier isolation.
• Offshore Drilling & Production Platforms: Topside utility fluid control, firewater deluges, gray/black water disposal headers, and drain pan manifolds.
• Municipal Water & Wastewater: Sludge handling lines, pump discharge shut-off valves, clarifier basin isolation, and filtration backwash control.
• Industrial Chemical & Power Facilities: Low-pressure steam distribution, cooling tower fan dampers, condensate loops, and batching tank shutoffs.

Frequently Asked Questions

What does the “ALS” suffix stand for on the RCEL-100?

ALS” stands for Auxiliary Limit Switches. In addition to the two primary mechanical travel limit switches that shut down the motor at 0° and 90°, the ALS configuration includes secondary independent dry SPDT microswitches used for remote position indication, PLC input verification, or safety interlocking with auxiliary equipment.

Can this actuator be powered with standard 110V or 24V DC supplies?

No, this specific model (RCEL-100 1-ph 230V ALS) features a motor and internal step-down circuitry wound specifically for single-phase 220–240V AC power (50/60 Hz). Supplying 110VAC will result in motor stall or thermal trip, while direct DC voltage will damage the internal stator.

Is the RCEL-100 self-locking, or does it require an external brake?

The RCEL-100 is fully self-locking. It utilizes a precision machine-cut steel worm driving an aluminum bronze worm gear. The mechanical reduction ratio prevents high back-pressures or fluid dynamic forces on the valve disc from turning the motor shaft, eliminating the need for complex mechanical solenoid brakes.

How do I manually operate the valve during a black-out or power outage?

Pull the manual declutch lever located on the actuator housing to engage the handwheel drive. Rotate the handwheel until the top dome indicator reflects the desired valve position. When electrical power is restored, energizing the motor automatically resets the declutch mechanism back to motor-driven operation without manual intervention.

Can the travel angle be adjusted beyond 90 degrees?

Standard factory setup is 90° travel for standard butterfly and ball valves, with mechanical adjustment bolts allowing ±5° trim at both open and closed positions. While specialized factory models exist with extended stroke cams (120° to 270°), standard units must be ordered with specific extended travel gearings.
