Engineered for High-Voltage Industrial Demands: The OMK series features a highly compact structure, effortless field installation, premium manufacturing quality, and extreme operational reliability. Designed as a direct upgrade to high-end imported alternatives, it delivers uncompromising heavy-duty automation under the toughest phase-controlled environments.
1. Applications
OMKEE explosion-proof electric actuators are widely utilized across global, safety-critical, and automated flow control sectors:
Oil, Gas & Chemical Processing: Refining, petrochemical plants, and hazardous fluid transfer.
Power Generation: Hydroelectric power plants and thermal power facilities.
Water Utilities & Treatment: Industrial wastewater systems, drainage pump stations, and power-driven agricultural irrigation.
Heavy Metallurgy: Iron and steel manufacturing, metallurgical smelting, and rolling mills.
Specialized Production: Pulp & paper mills, pharmaceutical processing, and food production.
Commercial Automation: Marine engineering, shipbuilding, and commercial building automation systems.
2. Premium Component Features
Heavy-Duty Enclosure & Protective Finish
Material: Premium ADC12 die-cast aluminum.
Surface Treatment: Subjected to strict artificial aging, shot blasting, and high-adherence electrostatic powder spraying. The finish coating thickness exceeds 0.2 mm and exhibits complete thermal stability at temperatures over 150°C.
High-Torque Worm Gear System
Worm Gear: Forged aluminum-bronze alloy blank tailored precisely to design proportions and CNC-machined to tight tolerances.
Worm & Output Shaft: Crafted from premium 40Cr alloy steel, fully heat-treated (quenched and tempered), and finished with a black-oxide coating for superior rust prevention.
Spline Connection: The output shaft and worm gear are joined via a heavy-duty spline connection, entirely eliminating the structural weak points and shaft snapping common in inferior single-piece designs.
Precision Quenched Gearbox
All internal reduction gears are precision-machined from high-quality tempered steel, boasting high dimensional accuracy, superior strength, low running noise, high fatigue limits, and excellent wear resistance.
Both ends of the reduction gear trains are stabilized by precision deep-groove ball bearings to cushion massive operational impacts. The reduction casing is cast from high-strength ADC12 aluminum for stable power transmission.
Industrial 3-Phase AC Motor
Engineered specifically for complex industrial duty cycles and high-torque demands. The motor handles 1.3x to 1.5x its rated torque.
Critical parameters—such as temperature rise, rotational inertia, and insulation voltage resistance—are specially optimized and lab-tested to guarantee continuous, frequent start-ups under full or overloaded capacities.
P6-Grade Low-Noise Bearings
All internal bearings feature minimal clearance, low noise, and high running accuracy, strictly matching the EMQ (ZV2) low-noise industrial standard and a P6 precision rating.
This is achieved through specialized super-finishing of the raceways, enhanced ball sphericity, and optimized cage configurations.
Advanced Stroke Limit Control
Equipped with an independently developed, user-friendly stroke control device. Operational calibration and field adjustment are easily executed through the convenient top "Adjustment Shaft," making commissioning simpler and more accurate.
Premium Industrial Sealing & Lubrication
Outfitted with imported German Obos dual-lip skeleton TC oil seals and premium O-rings for exceptional water/dust isolation.
The entire internal gearbox is pre-lubricated for life with authentic imported Mobil industrial-grade grease.
3. Engineering Layout & 100% Quality Assurance (QA)
UG Digital Simulation: Designed by senior valve automation specialists with over 10 years of experience. Structures undergo comprehensive 2D/3D modeling and advanced UG software simulation before die-casting mold approval.
4-Axis CNC Precision Machining: Vital parts are processed on imported high-precision 4-axis machining centers utilizing high-efficiency pneumatic fixtures to eliminate alignment errors.
Coordinate Measuring Machine (CMM): Post-machining dimensions are fully verified via high-precision CMM testing to align perfectly with target engineering tolerances.
The 5-Stage Factory Testing Protocol (100% Inspection):
Torque Verification: Every completed unit is torque-tested under both nominal and negative voltage conditions to verify a stable 1.3x torque safety margin.
Dielectric/Insulation Test: Insulative properties are fully tested at an extra-high voltage of 1500V applied to any of the motor leads for 1 minute without any trace of insulation breakdown.
Batch Endurance Testing: Regular random batch sampling subjects units to continuous full-load operating tests for 48 hours to verify extreme operational endurance.
Pressurized Submersion Leak Test: Every single actuator is submerged in water and pressurized to 0.2 MPa internally through its waterproof cable gland. A strict 10-minute hold with zero air bubbles certifies a flawless hermetic seal.
Final Quality Audit: Certified QA inspectors complete a comprehensive aesthetic, mechanical, and electronic review of each unit prior to issuing the final factory release stamp.
