Simple introduction
Q641F flange ball valve is that it has the same rotation of 90 degrees to lift action, there is a circular hole or channel through its axis, the ratio between the sphere and the channel opening should be like this, that is, when the ball rotates 90 degrees, the inlet and outlet should all present a sphere, thus cutting off the flow.
Pneumatic flanged ball valves only need to the operation of the gas rotate 90 degrees and small rotational torque can be closed tightly, full equality of the valve body cavity for medium resistance is very small, straight flow channel, usually do think the optimal xuan direct ball valve open and close with, but in recent years has been the development of ball valve designed to make it with throttling and control flow.The main characteristics of the ball valve is its compact structure, easy to operate and maintenance, suitable for water, capacity, acid and natural gas and other general working medium, but also suitable for thousand work pieces of harsh medium, such as oxygen, hydrogen peroxide, methane and ethylene.Ball valve body can be a whole, can also be combined.
