CWG Series Worm Gearboxes: Flexible & Economical Solutions for 90° Rotary Valves

The CWG Series is a line of worm gearboxes specifically designed for general industrial applications, particularly in water supply, drainage, and the metallurgical industry. It is the optimal choice for operating quarter-turn (90°) valves such as butterfly valves and ball valves.

The product not only excels as a manual operator but is also easily interfaced with Electric Actuators to upgrade to an automated control system.

Key Highlights of the CWG Series

1. Flexible Design – Optimized Installation

• Double Bushing Structure: Allows technicians to easily change the keyway position relative to the valve shaft, making assembly faster and more precise.

• Full Customization: Users can select the rotation direction and input shaft position to best fit the actual installation space.

2. Durability & Absolute Protection

• IP67 Standard: The device is completely dust-tight and waterproof (temporary immersion), ensuring stable operation in outdoor environments or damp valve pits.

• Double Sealing: A dual-layer sealing structure at the terminal box provides absolute protection for internal components against moisture ingress.

3. High-Precision Calibration

• ±5° Adjustable Stopper: This feature allows for precise fine-tuning of the stopping points at both ends of the stroke (fully closed and fully open), ensuring valve tightness and safety.

Practical Applications

The CWG Series is widely trusted in:

• Water Industry: Pumping stations, wastewater treatment systems, and municipal water supply networks.

• Heavy Industry: Steel mills, hydraulic systems, and production lines.

• Automation: Serving as a secondary reduction gear for electric actuators like the SMB and L120 series.
