Key Component Features & Material Engineering

1. Rugged Enclosure (ADC12 Die-Cast Aluminum)

The housing is constructed from heavy-duty ADC12 die-cast aluminum, treated with aging and shot-blasting processes. It features an advanced thermo-sprayed powder coating with a thickness greater than 0.2 mm. This durable shell easily withstands continuous temperatures above 150°C without degradation.

2. High-Torque Motor with Heavy Safety Reserve

To handle erratic pipeline loads, OMKEE engines the OMK-10C motor with a 1.3x to 1.5x torque safety reserve. Crucial parameters—such as motor temperature rise curves, rotational inertia, and insulation strength—are strictly tested. This design ensures the actuator can handle frequent start-stop cycles, even under full or overloaded conditions.

3. Spline Joint and Forged Worm Gear Drive

The inner copper worm wheel is forged from a high-performance aluminum bronze alloy, paired with a 40Cr alloy steel worm shaft that has undergone thermal tempering and black-oxide anti-rust treatment.

Instead of fragile one-piece structures that snap under heavy stress, the OMK-10C relies on a high-strength spline connection to lock the output shaft and the worm gear together. This setup spreads mechanical stress evenly across the joint.

4. Precision Gearbox & Low-Noise P6 Bearings

• Premium Reduction Gears: All reduction gears are precision-cut from high-grade quenched and tempered steel, yielding high fatigue resistance, minimal wear, and low operating noise.

• P6-Class Bearings: Both ends of the gear units are supported by P6-grade deep-groove ball bearings built to the low-noise EMQ (ZV2) standard. This setup controls internal vibration and resists sudden load shocks.

• Lubrication & Seals: Features imported premium Mobil grease and authentic twin-lipped skeleton TC oil seals from the German brand Oubaisi to prevent any grease leakage.

5. Intuitive External Stroke Limits

The OMK-10C uses a proprietary stroke adjustment mechanism. Field technicians can adjust the open and close limits directly using the external top adjusting shaft, making commissioning fast, safe, and precise.
