Rare application valves
Lined & Sleeved Valves
When we are dealing with extreme corrosion and the line is pressurised, lined and sleeved valves are the only available alternative for such services.
Even a minute defect in the lining or the sleeve can cause valve failure through heavy corrosion.
To avoid that, at Venus Engineering Works we check the entire lining or sleeve with a high-voltage spark test and confirm that the hardness, tensile strength and chemical properties of the lining material meet the required standard specifications.
We have experience of working with a very wide array of materials, including:
- Rubbers (natural, nitrile, butyl, EPDM, silicone, ebonite, etc.).
- Teflon (PTFE, PFA, RTFE — glass filled, carbon filled, cobalt filled, etc.).
- Nickel coating and cladding for extreme corrosion and erosion resistance.
- Tungsten carbide; amorphous carbide; boron carbide; stellite 6 coatings; etc for extreme erosion services.
- Glass coating and glass flake coating for corrosive and erosive services.
