Design Range

Size Range: NPS 1/2 to 2
DN 15 to 50

Pressure Class Range: 600 to 1500
PN 110 to 260

Seating Material: Metal

Features and Benefits

  • Increased uptime from the use of anti-thrust rings in the body-guided disc, which eliminates misalignment and galling
  • Greater process control due to integral hard-surfaced seat, which allows positive shutoff and seat life
  • Lower maintenance costs due to bolted bonnet, four-bolt design
  • Longer service life from positive metal to metal stop design that prevents over-compression of the gasket
  • High-performance delivered through optimization of flow passages to minimize flow direction changes and reduce pressure drops
