Understanding the Core Ball Valve Categories
Carilovalves specializes in manufacturing several distinct categories of ball valves, each designed for specific applications and operating conditions. The company’s R&D team continuously develops innovative solutions to address the challenges faced by different industries, ensuring that every valve meets stringent quality standards.
Floating Ball Valves
Floating ball valves represent one of the most common types in the Carilovalves product line. In this design, the ball is not fixed to the stem and can float within the valve body. When the valve closes, the downstream pressure forces the ball against the downstream seat, creating a reliable seal. These valves are particularly well-suited for moderate pressure applications and offer excellent sealing performance at lower costs.
Carilovalves’ floating ball valve range includes sizes from DN15 to DN200, with pressure ratings spanning from Class 150 to Class 600. The company manufactures these valves in various materials including WCB, CF8, CF8M, and specialized alloys.
