  • Gate and Seat - double-sided & reversible solid tungsten carbide, extends the service life and provide substantial cost savings compared to the standard single sided design
  • Trim Sizes - available in 2" and 3" max orifice pressure balanced configurations
  • Bonnet Nose - stellite overlaid, can be rotated to shift surface wear; significantly extending service life
  • Wear Sleeves - heavy wall tungsten carbide protects outlet spools from erosive flow conditions
  • Inlet & Outlet Spools - adaption design allows spools to be configured with ANSI, API, Hammer union or other various high-pressure connections
  • Large Body Cavity - disburses volatile solid accumulation allowing for maximum trim life
  • API -6A PSL 3 - high quality manfacturing standard
  • Gear Actuated - design allows for fine incremental flow rate changes
  • Digital Position Indicators - supplied for accurate adjustments
  • Manual Override and Quick Disconnects - configured to assist with service safety
  • NACE MR0175/ISO - built to meet or exceed standard


  • Operators - Hydraulic Gear, Piston or Manual Gear
