Sliding Disc Valve SSC

The SSC-type valve is a sliding disc valve with a ceramic sealing system for open/close function and control tasks, for use in highly corrosive and extremely abrasive media. It is designed for extreme conditions, where either high switching frequencies and a long service life are required, or where severe abrasion occurs in the control position but dead space cannot be permitted inside the valve.The functional principle is based on three floating ceramic discs that seal against each other. The middle disc shifts linearly.Different geometric shapes of disc apertures permit specific control characteristics. The two outer discs are stationary. Springs are used to compress the sealing system.The medium only comes into contact with ceramic components and seals, so that special materials are not normally required for the housing.


Areas of application

Waste incineration plants:

  • Dosing of HCl washing water (prewasher)
  • Dosed addition of lime milk to absorber
    (pH control, desulphurisation)

Chemical industry:

  • Alternative to PTFE/PFA-lined valves, where medium is abrasive and/or tends to diffusion.
  • Alternative to valves made from special materials (e.g. Hastelloy, titanium, etc.).
