REVOLUTIONARY SEAT DESIGN RESULTS IN 50% LONGER LIFE. TUFSEAT® Metal Seated Ball Valves by Krombach outperform the industry, they combine critical safety and performance features required for demanding chemical, petrochemical, and refining applications.
50% LONGER SERVICE LIFE
Consistent seat-leak performance and torque throughout the life of the valve for HIGH CYCLE AND SLURRY APPLICATIONS.
TUFSEAT® valves are equipped with a standard self-cleaning system that removes excess particles, minimizes leakage, and extends product life.

Additionally, the valves are fitted with fire-safe body gaskets in compliance with API 607.
Successfully passed the sand slurry test, 1500 cycles at 6 bar
To demonstrate performance in the toughest slurry applications, KROMBACH®'s TUFSEAT® Ball Valve (3” - Class 300) was tested under unprecedented conditions in a closed-loop system:
Slurry with 10% Solids
Highly erosive foundry sand: 0.15-0.6 mm, or 6-24 thousands of an inch
Fluid velocity: 3.6 m/s (from 60 m3/h ), or 12 ft/s (from 264 gpm)
The valve has successfully passed the sand slurry test, 1500 cycles at 6 bar. The TUFSEAT® Ball Valve continued to perform at Class V seat leakage after the 1500 cycles. Torque stayed stable throughout the test. In summary, the valve was not damaged, and all soft seals were in good condition.
