Dreifach exzentrische Absperrklappe

The tripleeccentricbutterflyvalve provides matched performance, reliability and quality for the harsh conditions of critical process applications, steam isolation, high cycle frequency, and temperature extremes, The superior design of the disc/shaft engagement and the precision machined sealing components combine with innovative design geometry to provide improved cycle life, lower operating torque, and reliable performance in extreme temperatures. Feature -TripleEccentric Design Eliminates wear associated with sealing surface contact and maintains sealing integrity and high cycle life. -Wide Angle Seat Design Eliminates wedging and binding of the seat/disc engagement. -Bubble-Tight Closure Ensures process efficiency with reduced cost of maintenance. -Self-Centering Disc Design Accommodates thermal cycling and temperature without binding. -Robust Single-Piece Shaft Minimizes shaft deflection which promotes bi-directional sealing. -No Plastics or Elastomers Standard design provides fire safety. -Bearing Protector Rings Prevent solid particles from coming in contact with bearing surfaces. -Blow out-Proof Shaft Complies with API 609 to improve safety for operating personnel. -Low Break and Operations Torque Enables simplified, cost-effective automation TripleOffset Design As the name implies, there are three separate offsets designed into the triple offset butterfly valve. Two of the offsets apply to the location of the shaft in respect to the centerline of the bore and the centerline of the disc/seat sealing surfaces:Offset 1: The shaft is offset behind the seat axis to allow complete sealing contact around the entire seat.
