Krombach? Triple-Eccentric Valves (Tri-EX) AK110 come in fabricated designs from 4¡± to 112¡± and feature non-rubbing rotation to minimize required torque while maximizing life span of the seat and laminated seal ring. Valves specially designed to shut off in high temperature service where other, resilient seated valves are not well suited, such as many severe service refining and power applications.

- 4. 4 Design Features www.craneenergy.com ? Flexible,floating laminated seal ring ? One-piece stainless steel shaft ? Live-loaded packing ? Bearing protectors ? Top mounting flange according to ISO 5211 ? Gear,Pneumatic,Electric,or Hydraulic Actuation Packages Design Features Gas Tightness Flexible seal ring with multiple laminations of 316Ti Stainless Steel and graphite (standard). ? Graphite laminations give the elasticity that ensures repeatable,tight shutoff. ? Graphite provides lubrication,reducing wear and friction,and extending lifetime. Closing Force Krombach Tri-Ex is torque-seated; the torque generates the closing force to tighten the valve. More torque equals a tighter seal;no overtravel/ limit stop needed. Seal Ring The seal ring is mounted on the disc and is self- centering, improving the sealing performance of the valve.

Three offsets ensure non-rubbing rotation, minimizing torque required and maximizing seat/seal ring lifetime. First Offset (1) Seat has axial offset to the shaft Second Offset (2) Shaft has offset to the center of the valve Third Offset (3) Seat has a cone shape.The top of the cone has an offset to the center of the valve Triple-Eccentric (Tri-EX) Design Triple-Eccentric (Tri-EX) Design Third Offset 3 (Tri-EX) 1 2 3 First Offset 1 Second Offset 2 Ex 1 Ex 2 Ex 1 a
