Product overview

  • FCCV1 Ceramic Ball Valve - product overview
  • The FCCV1 standard ceramic ball valve is designed for corrosive, abrasive and scaling service. Valve-stem options listed in the catalogue include 316/316L stainless steel, HC alloy, Monel alloy and structural ceramics, selected to match the operating medium
    The FCCV1 uses a symmetrical body for bidirectional sealing. A broad scraper-type seat clears particles from the sealing path, and the ceramic ball and seat are ground as a pair. The packing box uses a live-load arrangement to maintain packing force as wear occurs. The ceramic flange surface separates the metal flange from the process medium

Design and construction

  • FCCV1 Ceramic Ball Valve - design and construction
  • Broad sealing surface with scraper-type valve seat for reliability and long life
    Matched and ground ball and seat surfaces ensure sealing
    Packing box with "live load" for constant load under wear, prolonging packing life
    Symmetrical valve design for bidirectional sealing, with no flow-direction restriction
    Large ceramic flange surface protects metal flange from erosion and corrosion
