This advanced valve design incorporates dual-axis offset geometry to significantly enhance performance beyond conventional butterfly valves. The innovative configuration delivers:
60-80% reduction in operational torque
Extended service intervals (3-5× standard valve lifespan)
Reliable performance in extreme conditions (600℃/PN40)
Secondary offset: 5-15℃ stem inclination enabling frictionless initial rotation
Bolted connection with pressure-adaptive gaskets:
High-temp: Spiral-wound metal/graphite
Corrosive media: PTFE-encapsulated
:
Disc edge: Stellite 6 overlay (HRC 58-62)
Seat: 316L + flexible graphite matrix
:
Bubble-tight shutoff (ANSI Class VI)
100,000-cycle endurance testing (MSS SP-67)
<50ppm (ISO 15848-1)
Fire-safe certification (API 607/ISO 10497)
