● Compact structure, easy to operate: the ball valve consists of a spherical ball with a central hole and a valve body, the ball can be rotated 90 degrees to control the flow of fluid.
● Small flow resistance: ball valve in the fully open state, the ball channel, the valve body channel and the diameter of the connecting pipe are equal and in a straight line, the medium can flow through without loss.
● Good sealing performance: the sealing element of the ball valve usually adopts O-ring or other sealing materials, which ensures the sealing performance under various working conditions.
● Low maintenance cost: the structure of the ball valve is simple, reliable operation, maintenance and repair costs are relatively low.
Application areas
Ductile iron flanged ball valves are widely used in petroleum, chemical, electric power, metallurgy, medicine, shipbuilding and other industrial fields and low-pressure civil water supply and drainage fields. In addition, ductile iron ball valves are also feasible and beneficial in the electric heating industry due to their excellent performance.
