Highly corrosive and extremely abrasive media quickly push many valves to their limits. Typical examples include HCl wash water and lime slurry in waste-to-energy plants, or corrosive suspensions in the chemical industry. We developed sliding disc valve SSC specifically for these conditions.
How the ceramic sealing system works
Three ceramic discs seal against each other. The two outer discs are fixed, while the middle one moves linearly. Springs compress the system. The fluid comes into contact only with ceramic or seals—therefore, special alloys in the housing are usually not necessary.
On/Off and control in a single valve assembly
The SSC is suitable for high switching frequencies and a long service life. It provides reliable control even when severe abrasion occurs in the control position and no dead space is permitted in the valve. The control characteristic can be adjusted by changing the shape of the disc orifice.
In the chemical industry, it serves as an alternative to PTFE/PFA-lined fittings and to valves made of Hastelloy or titanium. A high-temperature version rated up to 450 °C is available as an option.
Where do your fittings reach their limits in terms of abrasion and corrosion?
