  1. LaroxFlowsys The Solution You´ve Been Looking For

  2. Conventional Industrial Knife Gate types Face seal KGV’s Edge seal KGV’s Not to be used on Slurry

  3. Face seal knife gate valves Designed for the paper industry. Face seal valve was original design. Knife designed to “cut” fiber. Original valve, metal seat only. Light duty applications only.

  4. Edge seal knife gate valves Designed for the paper industry. Face seal valve was original design. Edge seal was “next generation. Knife designed to “cut” fibre. Only available with an elastomer seat. Light duty applications only.

  5. Problems with Face and Edge Seal KGV’s when used on slurry • Wear • Blockage • Jamming • Leakage

  6. Problems with Face and Edge Seal KGV’s Packing is the only seal Packing requires constant adjustment Solids trapped in valve body stops the gate closing No gate lubrication Uni directional Valve will leak once seat / gate wears Solids trapped in valve seat stops the gate closing Seat directly in path of slurry Entire valve replaced once seat wears

  7. How Heavy Duty KGV Differ from Conventional KGV’s ? Bi directional Self lubricating gate Double sealing No packing – no adjustment Solids expelled from valve seat 100% Isolation No seat in slurry flow Replaceable rubber sleeves Conventional metal seated valves Larox Heavy duty KGV XPacking requires constant adjustment XPacking is the only seal XNo gate lubrication X Uni directional X Seat directly in path of slurry XValve will leak once seat / gate wears XSolids trapped in valve seat stops the gate closing XEntire valve replaced once seat wears

  8. Larox new range of Heavy Duty KGV’s Wafer (LKW) Flanged (LKF) High pressure (LKH) The SolutionYou´veBeenLooking For

  9. Wafer LKW 10 bar rated Wafer design 50-600mm diameter Cast Body NR sleeve DIN or ANSI 316 gate Gate protection Flushing ports Manual and actuated Stem Protection Flushing Ports Standard accessories Certification Other options considered

  10. Flanged LKF 10 bar rated Flanged design 50-600mm diameter Cast Body NR sleeve DIN or ANSI 316 gate Gate protection Flushing ports Manual and actuated Stem Protection Flushing Ports Standard accessories Certification Other options considered

  11. High Pressure LKH 20 bar rated 50-600mm diameter Cast Body NR sleeve DIN or ANSI 316 gate Gate protection Flushing ports Manual and actuated Stem Protection Flushing Ports Standard accessories Certification Other options considered

  12. Built in standard features Cast handwheal Encapsulated stem Enclosed heavy duty bearing Stem bellows Heavy duty frame with lockout and switch brackets 316 s/s gate Lubricated upper seal Heavy duty cast body Replaceable ring sleeves Flushing

  13. Built in standard features Encapsulated stem Heavy duty frame with lockout and switch brackets Open body suitable for flushing 100% full bore when open

  14. Built in standard features 316 s/s gate Other materials available also coating Replaceable ring sleeves with integrated support ring

  15. Built in standard features Standard protection 100% tight shutoff solids expelled into valve body

  16. Valve Function All Larox Heavy Duty Knife Gate Valves are built with a cast body and features a heavy-duty stainless steel gate. Removable seats on either side of the blade provide a bi-directional unobstructed flow when open and 100% tight when closed There are no metal parts in contact with the slurry when open Any solids are pushed into the body when closed and can be flushed, flushing ports as standard

  17. Valve Function How the rubber ring sleeves work Matching elastomer ring sleeves are placed in the valve housing to seal against the gate when the valve is closed and seal against each other when the valve is open. A stiffener ring molded into the elastomer retains the roundness of the sleeves during opening and closing cycles. This tight seal contains the high internal line pressure. Double seated design provides bi-directional flow and tight shut off. NR as standard EPDM and other elastomers on request.

  18. Valve Function Secondary Seal The field replaceable elastomer secondary seal replaces conventional gland packing, providing both wiping and lubricating actions to the blade as it strokes via contact between the blade surface and the silicone grease filled contours of the seal itself. Lubrication of the blade allows for easier actuation and movement. There is no need to remove the valve from the line when replacing the secondary seal.

  19. Valve Function Actuators Enclosed bushing with a protected grease chamber means less operating force after long dormant periods. Rugged cast ductile iron hand wheel Stainless Steel riser stem with fabricated steel protector. All actuator types can be fitted including hydraulic, pneumatic and electromechanical Stem protection as standard
