Brief Introduction

The Q941F electric 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 to the channel port should be such that when the ball rotates 90 degrees, it should all present a spherical surface at the inlet and outlet, thereby cutting off the flow.
Electric flange ball valves only require a 90 degree rotation and a small rotational torque to close tightly. The completely equal valve body cavity provides a low resistance and straight passage for the medium. It is generally believed that ball valves are suitable for direct opening and closing, but in recent years, ball valves have been designed to have throttling and flow control functions. The main characteristics of ball valves are their compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids, and natural gas, as well as for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body of a ball valve can be integral or modular.
