First, the floating ball valve Overview:
Ball
valve is an important valve in the petrochemical industry,
long-distance pipelines and other fields have a wide range of
applications. The closure of the ball valve is a ball with a
hole (or part of the ball), the ball with the valve stem rotation, the
valve to open or close.
In
a variety of valves, the ball valve flow resistance of the smallest,
full-diameter ball valve opens, the ball channel, valve body and
connecting pipe diameter equal to a diameter, the media can flow almost
without loss.
Turn the valve 90 ° to fully open all the way, opening and closing quickly. With
the same specifications of the gate valve, globe valve comparison,
small size ball valve, light weight, easy pipe installation.
