What Are The Main Advantages of Cast Steel Ball Valves?
Cast steel ball valve make the hole with a circular hole as the opening and closing parts, the ball rotates with the stem to achieve the opening and closing action of the valve. So, what are the main advantages of cast steel ball valves?
1.the fluid resistance is small, fully open the ball channel, the area of valve body channel is equal to the connection pipe cross-sectional, and form a straight line, the medium flows through the cast steel ball valve, which is equivalent to flowing through a straight pipe, the fluid resistance is minimal.
2.open and close quickly, open and close are convenient and rapid.
3.the structure is relatively simple, smaller size, lighter weight. In particular, its height is much smaller than the gate valve
and the shut-off valve.
4.sealing performance is good. Cast steel ball valve is generally used with flexible soft seal.
