Crane ChemPharma & Energy launches new triple-offset butterfly valve

Crane ChemPharma & Energy has launched the new Crane FKX 9000 triple offset butterfly valve for the harsh conditions of critical process applications, steam isolation, and temperature extremes.

The new valve delivers high flow control, optimized Cv and low Delta P in a single valve.

Engineered to address the inherent dangers of demanding applications, the FKX 9000 adheres to the industry’s standards, delivering zero-leak shut off in high-temperature applications, hydrocarbon service, and emergency shutdown (ESD) service.

The valve’s seat angle design and Stellite hard-faced valve body seat deliver a longer seal life and improved abrasion resistance, even after extensive cycling.

Designed to eliminate wedging or binding of the disc and lower the operating torque, the Crane FKX 9000 can reduce total cost of ownership by up to 50%, according to the company.

The precision machined metal seat and seal ring deliver reliable and bi-directional shutoff in high-temperature, high-pressure, and severe service applications, among others.

The right-angle conical design facilitates an almost friction-less in-line sealing.

The valve’s stem seal design permits high fugitive emissions control (ISO 15848, Class AH) under recurrent and extreme thermal cycling, and reduces potential downtime.

Unlike position-seated ball, butterfly, or plug valves, the torque-seated Crane FKX 9000 self-adjusts to evenly distribute seal compression.

A “floating” seal ring and wide seal ring supporting gasket yield a better seal to eliminate binding and enhance performance.

The Crane FKX 9000 also delivers high performance in thermal expansion due to the optimal positioning of the pin connector, located in the lower portion of the disk.

Furthermore, its bearing design also helps to prevent shaft deflection and permits longer valve life.

“Capitalising on previous TOV design features, the next generation Crane FKX 9000 offers an array of new innovations that further enhance valve safety and performance,” said Ralf Becker, business line manager for Crane ChemPharma & Energy.
