Q41F Ball Valve

About product

The Q41F Ball Valve is designed with a spherical closure featuring a circular passage that rotates around a vertical axis for precise opening and closing of the flow channel. With the valve stem’s rotation, the sphere moves accordingly, ensuring a tight seal.

This type of valve requires a mere 90-degree operation and minimal torque to achieve a secure closure. To cater to specific operational conditions, various driving mechanisms can be incorporated, resulting in diverse control methods such as electric ball valves, pneumatic ball valves, and hydraulic ball valves.

Product Detail

The operational principle of the Q11F Threaded Ball Valve is as follows:

When the ball valve is rotated 90 degrees, the ball surfaces at the inlet and outlet align, effectively closing the valve and halting the flow of the medium.

When the ball valve is rotated back 90 degrees, the ball port aligns with the inlet and outlet, allowing for the flow to resume with minimal resistance.

The structural principles of the Q41F Ball Valve, Q641F Pneumatic Ball Valve, Q941F Electric Ball Valve, and Q11F Threaded Ball Valve are as follows:

1. Ball valves are not restricted by installation direction, allowing for fluid flow in any direction. They exhibit low fluid resistance, and full-bore ball valves have minimal flow obstruction.

2. Ball valves feature a simple structure, and compact size, and are lightweight, making them easy to maintain.

3. They provide reliable tight sealing. With two sealing surfaces, modern ball valves utilize various plastic materials for excellent sealing performance, ensuring complete isolation. They are widely used in vacuum systems as well.

4. Ball valves are suitable for frequent operations, with quick and lightweight opening and closing. They provide convenient operation, requiring only a 90-degree rotation from fully open to fully closed, enabling remote control.

5. Maintenance is convenient due to the simple structure of ball valves, and the seals are typically movable, allowing for easy replacement.

6. Ball valves exhibit excellent sealing performance. When fully open or fully closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve sealing surfaces during medium flow.

7. They have a wide range of applications, accommodating diameters from a few millimeters to several meters, and are suitable for both high vacuum and high-pressure systems.

8. Due to the wiping action during the opening and closing process, ball valves can be used with media containing suspended solid particles.

9. Ball valves offer low fluid resistance, resulting in minimal vibration and low noise levels.
