Nippon Gear LSB Electric Actuator: Intelligent Valve Control & Absolute Waterproof Solution

Nippon Gear proudly introduces the LSB Series – a new generation of electric actuators featuring a breakthrough design that is compact and lightweight yet delivers superior driving power. This is a world-class solution for automating valves in the most demanding environments.

Key Advantages of the LSB Series

1. IP68 Waterproof Rating (Submersible up to 10m)

The hallmark of the LSB Series is its IP68 protection standard. The specialized design allows the device to operate stably even when submerged at a depth of 10 meters for 72 consecutive hours. It is the #1 choice for flood-prone areas or water treatment stations.

2. Compact Design – Powerful Output

Despite its streamlined appearance, the LSB Series boasts a torque of up to 1000 N·m and a rated thrust of up to 160kN. Ultra-durable gearing combined with next-generation torque and limit switches ensures absolute precision in valve opening and closing control.

3. Global Explosion-Proof Certifications

The product meets the most stringent standards, including IECEx (Exd II CT4 Hydrogen), TIIS, KOSHA, ITRI, and more—ensuring maximum safety for operations in explosive environments such as the oil, gas, and chemical industries.

Practical Applications

LSB actuators are designed for perfect compatibility with:

• Direct Connection: Multi-turn valves such as Gate Valves, Globe Valves, Sluice Valves, and Discharge Valves.

• Combined with Gearbox: Controlling part-turn valves such as Butterfly Valves, Ball Valves, and Dampers.

• Target Industries: Thermal/Hydroelectric power plants, wastewater treatment, oil and gas, marine, and pulp and paper production.
