Valves

Conventional ball valves are common practice. There are applications were these valves are not successful:

-extreme wear due to abrasive media

-high temperatures

-corrosion

Short life time or bad performance is a logical consequence.

Ceramic valves are a solution for following applications:

Applications

Fertilisers	nitrate slurry, flow of ammonium nitrate 180°C
Pigments	extraction (H2SO4, 70°C), transport of a TiO2 slurry
Energy/waste	desulfuration of fly as in power plants, transport of lime stone
Catalyst	"Kellogg-Cracker", abrasive catalyst, temperature 50-800°C (thermo shock)
Steel industry	injection of carbon powder in a furnace, injection of alloys in a melt, "scale" treatment, pneumatic transport, desulfuration
Plastic	molten plastics, components in plastic, polycarbonate factories
Pneumatic-transport	lime stone, glass, quartz, cement, fly as etc.
Pulp/water	Dosing of CaCO2, MgO2, MgSO2, Kaolin, Quartz sand "Bentonite" , Na2SO4

For some valves our partner is (since 1990) Cera System GmBH.
