Ball Valve - Education Model

Ball Valve Educational Model – 3D Printed Functional Demonstration

Description

This 3D printed ball valve model is designed as a clear and practical educational tool for demonstrating the working principle of a quarter-turn ball valve.

The red handwheel actuates the internal ball. By rotating the handwheel 90 degrees, the bore either aligns with the flow channel (open position) or turns perpendicular to it (closed position).

This makes the model ideal for explaining:

• The quarter-turn operating mechanism
• Open vs. closed valve positions
• Flow alignment and shut-off principle
• Basic fluid control concepts

The design is optimized for easy printing and assembly, making it a great project for educational environments, technical schools, and makerspaces.

Assembly Instructions

1. Assemble the blue housing
   Put the housing parts together and roughly align the mechanical stops.
2. Insert the ball
   Place the ball inside the housing.
3. Attach the handwheel
   Connect the handwheel to the ball.
   Before fixing it in place, check the stop position to ensure correct orientation.
4. Fine adjustment
   Rotate the handle to precisely align the stop positions.
   Make sure the 90° rotation correctly represents the open and closed states.

Recommended Use Cases

• Technical education
• Mechanical engineering basics
• Industrial valve training
• Fluid mechanics introduction
• Maker workshops
• Demonstration model for presentations
