GD-series Aluminum Declutch Part-turn Gearbox

Introduction and Features

The Aluminum Declutch Gearbox is specially designed for butterfly valves, ball valves, and plug valves,s etc., together with pneumatic actuators. This device allows manual operation during installation, system testing, and when the air resource is not loaded. It can be mounted directly on most of the popular rack & pinion style pneumatic actuators in the market. Superiority, it does not need a distance plate installed between the pneumatic actuator and the declutch gear.

- A simple and compact design, a light-weight device.

- ISO 5211 connecting standard.

- Easy to switch from manual drive to pneumatic drive by using the wrench retainer.、

- Internal parts are lubricated with special lubricant when the device is assembled.

- Weatherproof is IP65.

- GD series products output torque range varies from 180 to 5500 N · m.

- 0-90 angle adjusting.

With a modern factory spanning 30,000 square meters, we are dedicated to providing high-quality, highly reliable critical components for clients in the motorcycle and industrial sectors.

Our positioning goes beyond that of a traditional component supplier. Through a deeply vertically integrated manufacturing model, we maintain autonomous control over the entire production process—from raw material smelting and casting to precision machining, surface treatment, and final assembly. This effectively ensures consistent product quality, on-time delivery, and controllable costs.

**II. Our Core Strengths and Hardware Capabilities**

Our core advantages are built upon substantial hardware investment and a complete process chain:

**1. Complete Process Chain and Advanced Equipment:**
We possess a full set of equipment from blank manufacturing to final assembly, ensuring full-process quality control.
*   **Smelting and Casting:**
    *   3 non-ferrous metal smelting electric furnaces: Ensure the purity and precise composition of aluminum alloy raw materials.
    *   20 metal gravity casting machines and 6 die-casting machines: Cover a wide range of casting needs from complex thin-walled parts to high-strength structural components, providing flexible casting solutions.
*   **Heat Treatment and Surface Treatment:**
    *   6 heat treatment equipment units: Provide treatments such as T6, solution, and aging to significantly enhance the mechanical properties of castings.
    *   2 shot blasting machines, 2 vibratory finishers, 10 polishing machines: Used for workpiece cleaning, deburring, and surface finishing.
    *   300-meter automated painting line: Capable of applying primer and topcoat to meet various appearance and anti-corrosion requirements.
    *   3 ultrasonic cleaning machines: Achieve thorough cleaning of deep holes and complex structures, ensuring assembly quality.
*   **Precision Machining:**
    *   5 machining centers, 18 CNC lathes, 30 conventional lathes, 10 milling machines: Form a robust machining cluster with capabilities including turning, milling, drilling, and tapping, enabling efficient completion of high-precision, complex parts machining.
*   **Final Assembly:**
    *   6 specialized assembly lines: Ensure efficient, orderly, and standardized assembly and testing of component assemblies.

**2. Technology-Driven and Quality Commitment:**
*   **Engineering Team:** We have an experienced R&D team with the capability for synchronous development with customers.
*   **ISO 9001 Quality Management System:** This forms the foundational quality management framework for our entire operation.
*   **International Explosion-Proof Certifications (e.g., ATEX, IECEx):** These key certifications are mandatory passes for our industrial valve actuators, gearboxes, and other products to enter potentially explosive atmospheres in sectors like oil, natural gas, chemicals, and mining. They prove our products are fully compliant with international explosion-proof standards in design and manufacturing, ensuring a high level of safety and reliability in hazardous environments. This provides crucial safety assurance and compliance for our global industrial customers.

**3. Diversified Market Application Experience:**
Our products are successfully applied in two major sectors, giving us broader technical vision and more innovative solutions.
*   **Motorcycle Sector:** Supplies high-quality aluminum alloy castings and machined parts for engines, frames, and braking systems.
*   **Industrial Sector:** Supplies gearboxes, handles, and pneumatic actuators to the valve industry, with products exported overseas.
