Knife gate valves SG73-E were used in Titanium Dioxide Factory in Sakhalin Island
Titanium dioxide (TiO₂) is one of the most widely used white pigments in industries like coatings, plastics, paper, and cosmetics. The production of TiO₂ requires various complex processes, including the handling of slurries and powders. In these processes, equipment reliability is crucial for ensuring both safety and efficiency. One critical component used in the handling and transportation of TiO₂ is knife gate valve , known for its ability to control the flow of slurry and powder in various industries.
Project Requirements:
The production of titanium dioxide involves high-viscosity slurries, often combined with aggressive chemicals, which can cause wear and tear on conventional valves. These slurries tend to be abrasive and can clog or erode standard valve designs over time. The customers need a type of knife gate valve, which can bear aggressive mediums, more open-shut times, control the flow rate and decrease the maintenance costs.
Seallon`s Solutions:
1. Seallon provided the SG73-E knife gate valves, which allow to cut through thick slurries without causing excessive wear. This is especially important in the production of TiO₂, where the abrasive nature of the slurry could quickly degrade other valve types.
2. Unlike traditional knife valves, SG73-E has a bonnet, reducing the risk of leakage from the stem, even when handling highly corrosive or abrasive materials like TiO₂ slurry. This ensures that the system remains safe and efficient.
3. The part of knifes (discs) were designed as a square shape, which make the valves control the flow rate of TiO₂ in the in the inclined pipe.
4. Knife gate valves SG73-E are designed for high durability, requiring less frequent maintenance and offering a longer service life compared to other valve types.
