Leakage control of the moving O-ring seal of Arc 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.
- 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.
