Control Ball Valve with Caged Trim
ABV KEY-C (TM) Valves are Quarter–Turn Control Ball Valves with a special caged Trim, designed for allowing optimal flow regulation in all critical conditions. This valve typology is extremely suitable in services requiring high rangeability combined with very high differential pressure between upstream and downstream of the valve.
The Caged Trim allows traditional Ball Valves to evolve in high performance control valves.
The Caged Trim is composed by a series of drilled plates located inside the ball bore, having the goal to partialize the pressure drop; as a result of this effect the system is able to reduce the chance of Cavitation or Flashing phenomena and to allow a sensible noise reduction.
Valves design is Trunnion mounted composed with 2 or 3 piece split bolted body, side entry according to API 6D.
Valves are generally single seated designed with DPE (Double Piston Effect) Technology, as a consequence they have one preferential flow direction but bi-directional tightness. Valves are always metal to metal seat design, with Tungsten Carbide or Chromium Carbide coating performed between ball and seat contact areas.
