Concentric : Single Piece Design - Molded Seat   Download Brochure

  • Molded-in resilient seat provides bubble-tight shutoff to 150 psi.
  • Offered in two body styles: wafer and lug. The lugged body is drilled and tapped for isolation and removal of downstream piping at full rated pressure.
  • Round, polished disc and hub edge provides 360 degree concentric seating, minimum flow restriction, lower torques and longer seat life.
  • Thru-stem design provides high strength and positive disc control with standardized end connection for operator interchangeability.
  • Extended neck allows adequate clearance for flanges and insulation.
  • Bi-directional, self-adjusting stem seal, located in the upper journal, suitable for vacuum and pressure while also preventing external contamination of the stem area.
  • Cast-in top mounting plate is an integral part of the body which is standardized to allow direct mounting of all kind of actuators.
  • Each valve is factory tested to 110 percent of specified pressure rating.
