drylin® lead screw technology and igus® plain bearings in process technology

Technical data:

  • What was needed: Error-free workflow in process technology
  • Requirements: Maintenance-free- & lubrication-free,  chemical resistance
  • Material: Maintenance-free iglidur® materials
  • Industry: Process engineering
  • Success for the customer: Lead screw technology and plain bearings from igus ensure faultless functioning of the bearing points
Shut-off valve:The shut-off valve enables the controlled closing and opening of flow openings or pipelines and regulates the flow of fluids in gas and liquid installations. The shut-off valves can be operated manually or with a motor. Unlike ball valves, the shut-off valve is not designed to shut off the flow with a single hand movement, but to throttle it continuously by turning the lead screw several times.

Wherever media are conveyed and dispensed, faultless functioning of the bearing points is indispensable. Due to the flow of liquids in gas and liquid installations, lubricants must not be used at the bearing points. Furthermore, maintenance work must be kept to a minimum.


The iglidur® materials not only help to mount completely lubrication-free, but are also characterised by the best sliding properties and their chemical resistance. Higher efficiencies and less maintenance are achieved. The drylin® lead screw technology ensures slow opening and closing of the valve.
