Series - 150 | PN6-PN25

Design Features
  • Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks
  • Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life
  • Extended neck allows for 50 mm (2″) of pipeline insulation
  • Integrally cast mounting pad provides direct mounting of actuators eliminating the need for costly brackets and couplings
  • Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life
