BGA Series Bevel Gear Actuators: High-Efficiency Lifting & Valve Solutions

The BGA Series is the latest generation of bevel gear actuators from Nippon Gear, specifically designed for Sluice Gates, Gate valves, and Globe valves subjected to high thrust loads. This series is the perfect successor to the legendary BA Series, which has been widely utilized in the water and energy sectors.

Key Highlights of the BGA Series

1. Superior Operational Efficiency (>90%)

Equipped with high-quality roller bearings at all moving positions, the BGA Series achieves an impressive transmission efficiency of over 90%. This ensures that manual valve operation is effortless, smooth, and requires minimal physical exertion.

2. Compact Design & High Reliability

• Integrated Thrust Bearings: Effectively absorbs thrust from the valve stem, enhancing the overall durability of the system.

• Fully Sealed Construction: The units are pre-filled with extreme-pressure grease and completely sealed, allowing for immediate deployment without complex initial maintenance.

3. Intelligent “Hammer Blow” Feature

The signature Hammer Blow mechanism generates sufficient impact force to ensure tight and secure valve closure, even when minor obstructions or slight jamming occur (Note: Model BGA-4 is designed with zero lost motion).

4. Seamless Electric Actuator Upgrade

One of the strongest advantages of the BGA Series is its flexibility. You can easily convert from manual to electric operation by mounting actuators such as the SMB, JMB, or L120 series using standard adapters, without needing to replace the entire system.

Practical Applications

The BGA Series is the premier choice for critical infrastructure projects:

• Water & Wastewater Treatment: Operating sluice gates and tidal gates.

• Power Plants: Controlling large-scale hydraulic and gate valve systems.

• Dams & Irrigation: Sluice gate systems requiring high thrust capacity.
