Features & Benefits

The Resolute Ball™ is a remarkably unique product designed to address a variety of customer challenges related to scale accumulation on the upstream surface of the ball that is common in applications with infrequent operation. Certain medias in industries such as pulp & paper, mining, petrochemical, and refining have a tendency to accumulate thick scale on the ball surface when left dormant over time. Scale must be scraped off of a traditional ball by the seat, dramatically increasing torque, making the valve difficult to operate, often leading to premature valve failures such as seat leakage, sheared stems, and seized operation. The unique Resolute Ball™ design offers a drop-in solution for this common problem.

Standard ball valves use a spherical surface that maintains contact between the ball and seat throughout the 90 degree operation. As the valve operates, the scale that has accumulated on the spherical surface of the traditional ball travels across the seat sealing area, resulting in increased torque, scored seal surfaces, and potential failure to operate. The unique, engineered geometry of Bray's Resolute Ball™ Valve has been successful in helping our customers overcome these challenges. As the Resolute Ball™ rotates, media contact with the seat is drastically minimized throughout the quarter-turn operation due to minimal contact between the ball and seat after 10 degrees of rotation. The Resolute Ball™ geometry reduces wear by as much as 70% by enabling accumulated media particles to be flushed past the ball and seats. This unique design provides improved operation, extended service life, reduced valve operating torque, increased reliability, and reduced total cost of ownership for the customer.

The Resolute Ball™ is compatible as a drop-in replacement for multiple standard product lines including the one-piece Flanged ball valve RF15/RF30, two-piece Flanged ball valve F15/F30. Each of these high-performance product lines are field proven with an extensive global install base throughout a wide variety of industries.

Resolute Ball™ Design Advantages

Traditional Ball Design Challenges

 

Top View

Round0-5-min-2

Large spherical surface area allows media buildup on ball surface and downstream ball cavity.

Round15-5-min-2

Media buildup leads to seat damage, due to constant contact between ball and seat during full 90° rotation.

Round45-5-min-2

High valve torque is required to break significant media buildup. Valve could fail to operate, stem could shear, or seats could leak prematurely.

Square0-5-min-2

Square ball design minimizes effects of media buildup on ball sealing surface and allows particles to flow through ball cavity.

Square15-5-min-2

Seat life is extended, due to reduced media buildup and minimal contact between ball and seat after 10° of rotation.
