Laufer Valve

Leakage control of the moving O-ring seal of Shutter Valves

For maxiumum product safety of sensitive media

For maxiumum product safety LIAG® free flow shutter valves are available with a leakage monitoring system of the only dynamic O-ring. This specific design identifies possibile wearing defects of the seal and prevents any contamination from the outside environment.

Features

  • Maxiumum product safety for aseptic processes
  • No contamination from the outside environment by as a result of excessive wearing or a defective stem O-ring seal
  • Quick acting valve due to low operating torque requirements (ball-bearing supported main shaft)
  • Able to be retrofit to shutter valves

The special designed leakage chamber can act as a steam barrier or offer monitoring via means of a level conductor control (dilution of glycerine).

The pivoting axle is supported with a ball-bearing shaft for increased stability and less required operating torque compared with the standard shutter valve.
