Zirconia Ceramic Lined Ball Valves

Nil-Cor has combined two advanced materials technologies: graphite fiber-reinforced vinyl ester resin and tough new zirconia ceramic to produce the best performing and lowest cost valve for corrosive/erosive fluids. Available in sizes 1" through 8". Manual, automated on/off or precision factory assembled modulating control valves are available. Nil-Cor is the smart choice for your toughest erosive applications.

  • Ultra-High Molecular Weight Polyethylene (UHMWPE)-Lined Ball Valves

    Nil-Cor has developed an economical solution for less severe slurry applications, such as gypsum or WWTP sludge. Our UHMWPE liners combined with our Zirconia ceramic ball deliver outstanding service in these applications at half the cost of an all-Ceramic design. Since the UHMWPE liners are fully interchangeable with the Zirconia liners, it is easy to upgrade to ceramic should the need arise.
