  1. Main Design Features
  • Construção da carroceria: One-piece die forged body, dense structure, high strength, eliminates casting defects, suitable for high temperature and high pressure services
  • Bonnet Connection: Bolted bonnet design with 304/flexible graphite spiral wound gasket sealing
  • Disc Design: Renewable disc type, hardfaced seating surface for durability
  • Stem Design: Backseat feature allows packing replacement under pressure when valve is fully open
  • Operating Characteristics: Disc moves linearly along seat centerline, short stroke, reliable shut-off
  • Flow Direction: Flow below seat design, reducing operating torque and protecting packing
  • Packing: Flexible graphite packing, low emission design
  • Assento: Renewable seat rings or integral hardfacing
