Brief Introduction
Q641F flange ball valve has the same 90-degree rotation lifting action, with a circular through hole or channel passing through its axis. The ratio of the spherical surface and the channel opening should be such that when the ball rotates 90 degrees, the inlet and outlet should all present a spherical surface, thereby cutting off the flow.
The pneumatic flange ball valve only needs to be operated by rotating the air 90 degrees and a very small torque to close tightly. The completely equal inner cavity of the valve body provides a very small resistance and a straight flow channel for the medium. It is generally believed that the ball valve is suitable for direct opening and closing, but the development in recent years has designed the ball valve to make it have the function of throttling and controlling flow. The main features of the ball valve are its compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.
