SPRING RETURN BALL VALVE
What is a Spring Ball Valve?
Spring ball valves are industrial valves that use hollow balls combined with elastic spring mechanisms to open/close and maintain stable pressure in the pipeline system. The product is widely used in water, compressed air, heat, chemical and petroleum systems thanks to its high sealing ability, fast operation and outstanding durability.

SPRING RETURN BALL VALVE
Product Overview
The spring return ball valve is an industrial valve that uses a hollow ball combined with a spring mechanism to open and close automatically while maintaining stable pressure in the pipeline system. When the operator turns the handle, the spring is compressed; once released, the spring pushes the handle back to its original position, allowing the valve to automatically close. This design ensures safety, prevents leakage, and avoids fluid loss caused by forgetting to close the valve.
Main Components

| Body | Withstands pressure and connects to the pipeline | Stainless Steel 304 / 316 / Carbon Steel WCB |
| Ball | Controls flow, rotates 90° to open/close | Stainless Steel 316, polished for corrosion resistance |
| Spring | Provides return force for automatic closing | High-strength stainless steel |
| Stem | Transmits torque from handle to ball | Stainless Steel 304 / 316 |
| Seal | Prevents leakage, resists heat and chemicals | PTFE / Teflon |
| Handle | Manual operation with spring return | Stainless steel with vinyl grip |

Operating Principle
-
When the handle is turned, the ball rotates 90° to open the flow path.
-
When the handle is released, the spring automatically pushes it back to the closed position.
-
This mechanism ensures automatic sealing, safe operation, and leak prevention.
Key Advantages
✅ Quick operation — only 1/4 turn required
✅ Automatic return prevents accidental fluid loss
✅ High sealing performance, zero leakage
✅ Withstands high pressure and temperature
✅ Compact design, easy installation
✅ Simple maintenance and long service life
Applications
Widely used in:
-
Water supply and drainage systems
-
Compressed air and steam pipelines
-
Chemical and petroleum industries
-
Food, beverage, dairy, and cosmetics production
-
Pharmaceutical and environmental systems
