CCKFR Eccentric Rotary Control Valve

Summary:The CCKFR Eccentric Rotary Control Valve is a novel, high-performance control valve featuring a unique partially spherical valve core with an eccentric rotary design. The center of rotation for the valve core is offset from the axis of the rotating shaft, significantly reducing friction between the valve core and seat during operation. This minimizes wear on the valve seat, extending the valve's service life. Additionally, the valve incorporates a streamlined guide vane at the rear of the valve core, promoting stable fluid flow and enhancing overall operational stability. Moreover, this valve boasts exceptional performance, offering large flow capacity and a wide adjustable range, making it ideal for handling highly viscous media, as well as fluids containing particles, suspensions, slurries, and even fine mineral powders. It is particularly well-suited for controlling processes involving slurry-like materials.

The CCKFR Eccentric Rotary Control Valve is a novel, high-performance control valve featuring a unique partially spherical valve core with an eccentric rotary design. The center of rotation for the valve core is offset from the axis of rotation, significantly reducing friction between the valve core and seat during operation. This design minimizes wear on the valve seat, extending the valve's service life. Additionally, the valve incorporates a deflector wing at the rear of the valve core, promoting stable fluid flow and enhancing overall operational stability. Moreover, this valve boasts exceptional performance, offering large flow capacity and a wide adjustable range. It is ideally suited for handling highly viscous media, as well as fluids containing particles, suspensions, slurries, and even fine mineral powders. Its robust design makes it particularly effective for controlling processes involving slurry-like materials.

　　The CCK series of regulating ball valves is primarily characterized by its compact design and reliable sealing performance. The valve consists of key components such as the valve body, valve core, stem, and seat. Its closing member—designed as a sphere—rotates 90° around the stem's axis to achieve full opening or closing, making it ideal for remote control applications. When paired with a pneumatic piston actuator and associated accessories, the valve requires minimal actuation torque, enabling swift and efficient operation. In both fully open and fully closed positions, the sealing surfaces between the sphere and valve seat remain isolated from the process medium, preventing erosion even when media flows through the valve. This makes the CCK series suitable for handling common working fluids like water, solvents, acids, and natural gas—and also excels in handling more challenging media, such as oxygen, hydrogen peroxide, methane, and ethylene. As a result, these valves have found extensive use across various industries, including vacuum systems, where their robust performance and durability are particularly valuable. Additionally, due to the self-lubricating action during operation, ball valves like the CCK series can effectively manage media containing suspended solid particles.
