Expanding Gate Valve

  • Full bore design eliminates efficiently pressure drop and vortex, and eliminates washing by solids in fluid.
  • Gate use expanding type structure.
  • Achieve low torque operation and low wastage during open and close.
  • Metal seal is used between bonnet and body.
  • Soft seal or metal seal is used between gate and seat.
  • Inject sealant through injection valve to improve seal performance.
