Special features

  • Ceramic internal parts withstand wear and cavitation
  • Gas-tight shut-off in both directions of flow (leakage class VI)
  • Small face-to-face dimensions (56 mm)

The risk of corrosion and erosion is particularly high in steam lines that carry condensate. When corrosion occurs, metal particles are released from the steam lines and dragged along by the flow of steam. Downstream, they cause erosion.

Corrosion and erosion also affect the control valves installed in the steam lines. Nevertheless, steam is an essential heat transfer medium. It is used in many applications, such as the vulcanization of tires to give the rubber elasticity at good durability. This stage in the tire manufacturing process is characterized by high temperatures and high pressures. Under these conditions, the Type SDL 10 Sliding Disk Valve with ceramic lining by SAMSON CERA SYSTEM proved its worth in a six-month test conducted by a renowned tire manufacturer.

While detectable control deviations occurred after three months when using other control valves, the sliding disk valve by SAMSON CERA SYSTEM continued to perform accurately beyond this point. The seals and control disks made of wear- and corrosion-resistant ceramics were directly exposed to the flow of steam but did not show any signs of wear after six months in service. As pressure can be applied to the sliding disk valve from both sides, the tire manufacturer could forgo an additional ball valve that was previously needed.
