  • Absolutely No Atmospheric Bleed—Eliminates nuisance and wasteful bleed gas to atmosphere by utilizing a pilot-operated control system, which bleeds 100% of the gas to the downstream system.
  • Quiet Operation - Multiple noise attenuation options available which reduce noise by up to 25 dBa.
  • High Capacity—The highly efficient axial flow design produces exceptionally high capacities.
  • Versatility—Ideal for a wide variety of applications such as natural gas transmission and distribution systems, power plants, monitors and sour gas with inlet pressures up to 1480 psig / 102 bar.
  • Long Life in Severe Service Applications— The metal plug design deflects particles and debris away from the soft-seat, which gives excellent particle erosion resistance, prolonging service life.
  • Easy In-Line Maintenance—With the optional outlet flange spacer, trim parts such as the disk holder can be inspected, cleaned and replaced without removing the body from the pipeline.
  • Tight Shutoff—A knife-edged metal plug and soft seat provide bubble tight shutoff for use in applications where positive shutoff is required such as dead-end systems.
  • Full Pressure Rating—The equal inlet and outlet pressure rating of 1480 psig / 100 bar, which allows easier selection and requires no special startup or shutdown procedures.
