Neles Jamesbury 10" CL300 Q-Trim Control Ball Valve QR21DA10ACJA

The Neles Jamesbury QR21DA10ACJA is a high-performance 10-inch Class 300 control ball valve designed for precise flow control in demanding industrial applications. Featuring the innovative Q-Trim technology, this valve incorporates a perforated ball design that provides excellent noise reduction, anti-cavitation properties, and superior throttling capabilities, making it ideal for use in oil and gas, chemical processing, power generation, and pulp and paper industries. Constructed from durable CF8M stainless steel (equivalent to 316SS), it offers excellent corrosion resistance and can handle high-pressure and high-temperature environments up to 816°F. Key advantages include low torque operation for easy actuation, tight shutoff for minimal leakage, and modular design for easy maintenance. Compared to traditional globe valves, it provides higher flow capacity (Cv up to 10,000) with reduced pressure drop and better rangeability. Drawbacks may include higher initial cost and the need for compatible actuators. This unit appears used but in good condition with minor wear, no visible damage, and includes a side-mounted actuator port. It excels in applications requiring accurate control of viscous fluids or slurries, offering reliability and longevity in harsh conditions.
