KROMBACH® TUFSEAT® Performance Series Ball Valves

The Performance Series Krombach® Metal Seated Ball Valve combines critical safety and performance features required

for demanding service applications in chemical and refining markets.

Features And Benefits

  • LONGER SERVICE LIFE: Consistent seat leak performance and torque throughout the life of the valve for HIGH CYCLE AND SLURRY APPLICATIONS.
  • LOW VALVE OPERATING TORQUE: Reduced initial investment cost of automation through HIGH EFFICIENCY PACKING and LIVE LOADED SEATS.
  • TIGHT INDUSTRY STANDARD INLINE LEAKAGE: Bi-Directional, Class V or VI Seat leakage (API-598/FCI 70.2) through PRECISION LAPPING of ball and seats for a perfect fit.
