Product Category: Explosion-Proof Valve Automation / Quarter-Turn Electric Actuator
Product Overview
The OMK-Ex60A is a high-performance, explosion-proof electric actuator engineered for demanding industrial environments. Characterized by its compact structure, ease of installation, premium component quality, and rugged reliability, the OMK series provides precise quarter-turn control for ball valves, butterfly valves, dampers, and plug valves across hazardous and heavy-duty industries.
Key Features & Benefits
Certified Explosion-Proof Protection: Fully compliant with GB 3836.1-2010 and GB 3836.2-2010 standards, rated at ExdIIBT4 Gb for hazardous gas environments.
Submersible IP68 Enclosure: Confirmed by official SITIIAS testing to offer ultimate dust and continuous immersion protection.
High-Torque Heavy-Duty Motor: Custom-engineered motors provide 1.3 to 1.5 times the rated torque margin to handle sudden load shocks and frequent start-stops.
Advanced Ergonomic Stroke Control: Features a proprietary top-mounted "Adjustment Shaft" mechanism that makes on-site travel limit commissioning simpler and more accurate.
Premium Component Engineering
1. Heavy-Duty Industrial Enclosure
Material: High-grade ADC12 die-cast aluminum.
Surface Treatment: Subjected to aging treatment, shot blasting, impregnation, and oxidation.
Coating: Finished with premium AkzoNobel powder coating (thickness $>0.2\text{ mm}$), capable of withstand temperatures exceeding 150°C without degrading.
2. High-Precision Worm & Gear System
Worm Gear: Forged from custom-formulated aluminum bronze alloy and precision machined.
Output Shaft & Worm: Crafted from 40Cr alloy steel, heat-treated for superior toughness, and finished with a black oxide treatment for rust prevention.
Connection: The output shaft and worm gear utilize a highly reliable spline connection, eliminating the warping and snapping failures common in single-piece shaft designs.
3. Precision Reduction Gearbox
All reduction gears are precision-cut from premium quenched and tempered steel, delivering high precision, exceptional structural strength, ultra-low noise, and high fatigue/wear resistance.
Both ends of the reduction unit gears are supported by deep groove ball bearings to dampen noise and withstand long-term heavy load shocks. The gearbox housing is die-cast from ADC12 aluminum alloy for smooth power transmission.
4. Specialized Industrial Motor
Built to deliver 130% to 150% of the rated torque requirement.
Features optimized thermal dissipation (low temperature rise), low rotational inertia, and enhanced dielectric strength, guaranteeing continuous performance under full-load or over-load cycling.
5. High-Grade Bearings & Seals
Bearings: All bearings strictly conform to the EMQ (ZV2) low-noise, low-vibration standard with a precision rating of P6 grade.
Seals & O-Rings: Equipped with imported genuine German "Obers" dual-lip TC oil seals and premium gaskets.
Lubrication: Pre-lubricated with imported high-performance Mobil grease for lifetime smooth operation.
Rigorous Quality Control & Testing
Every OMK-Ex60A actuator undergoes a rigorous 3D design cycle via UG software simulation and is machined using high-precision 4-axis CNC centers with pneumatic fixtures. Dimensions are strictly verified by 3D CMM (Coordinate Measuring Machines).
Before leaving the factory, 100% of units must pass four critical inspections:
Torque Testing: Every unit is tested under rated and negative voltage variants to ensure a minimum 1.3x torque margin.
Dielectric/Withstand Voltage Testing: Subjected to 1500V high-voltage insulation tests for 1 minute without breakdown.
Batch Load Endurance Testing: Random batch samples undergo full-load continuous operations for 48 hours to verify fatigue life.
Submersible Waterproof Testing: Actuators are pressurized internally to 0.2 MPa via the waterproof cable inlet and submerged in water for 1 minute to ensure zero bubble leaks (IP68 validation).
Core Application Fields
The OMK-Ex60A is widely deployed globally across harsh industrial and automated process lines, including:
Energy & Power Generation: Thermal power plants, hydroelectric stations, and irrigation networks.
Hazardous Environments: Petroleum extraction, oil & gas pipelines, petrochemical refineries, and chemical processing.
Heavy Metallurgy: Iron & steel plants, metallurgy facilities, and mining processing.
General Process Industries: Pulp & paper, industrial water treatment, marine/shipbuilding, pharmaceuticals, building automation, and commercial food processing.
