​Key Features & Benefits

  • Tight sealing with flow in either direction
  • Precision-machined bodies for perfect seating of the liner and precise positioning of the shaft
  • Shafts have multiple bearings giving optimal guidance even after many years of use. No contact corrosion
  • Shaft retainer guarantees blow-out resistance of the shaft
  • Continuous forming lobe for stabilising the liner
  • Sealing surfaces are mirror polished and guarantee low torque combined with tightness

Options Available

  • Worm gearbox operated
  • Actuator operated

The LUG range is installed using bilateral screws and no nuts. LUG is assembled above ground to resolve problems of congestion. It is a range that can be adapted for all types of fluids and constraints. Like WAFERLUG possesses two friction points. This gate valve is used to dismantle one side of the installation while keeping the other side under pressure and in full operation.
