FEATURES :

• Choke body materials can be of forged, HIPped or cast construction.
• Robust cartridge trim (bi-directional flow option).
• Patented plug/seat design for heavily contaminated flows.
• Solid or balanced plug available.
• Dump tube/sparger (only for bypass to condenser)
• High-grade premium carbide trims for optimum erosion resistance.
• Brick stopper anti-collapse trim available.
• Choose from a wide range of actuator options.
• Seals are resilient and do not suffer from explosive decompression.

HF HIGH FRICTION CARTRIDGE TRIM :

• Divides the main flow into many small streams, increasing turbulence and noise peak frequency and maximising the pipe wall transmission loss.
• High energy levels, pressure and velocity are dissipated within the trim - avoiding erosion damage.
• Design of final stage ensures low-velocity non-interacting jets, avoiding unnecessary noise generation in the choke outlet.
• Various trim sizes can be used on different choke body sizes, to suit a wide range of process parameters.
• The inner tungsten carbide control elements are protected from impact damage by the outer cartridge sleeve.

HF-LCV ANTI-EROSION TRIM DESIGN :

On applications where there is a risk of high sand contamination, the HF-LCV trim design is the ideal choice. It has been independently tested and has proved very successful in some of the most erosive service conditions.

• Premium-grade solid tungsten carbide critical control elements.
• Solid tungsten carbide sacrificial plug nose.
• Shrouded plug seat, protected from the high erosive flow path.
• Hole development dead band - the seating area is removed from the main flow area.
• Stem scrapers prevent migration of sand into the stem seal area.
• Resilient plug seals with scraper rings.
• Metallic 'brick stopper' prevents solid particles impacting directly on the tungsten carbide.
• Optional tungsten carbide wear sleeve.
