The Sankey Cavity filler ball valve can handle a vast variety of fluids, semisolid and almost any viscous media in paint pulp, paper processing, FDA, Paint and process industries. Our zero cavity valves have a unique design in which a PTFE / MPTFE / CFT / Metal Cavity Filler are used to fill the void in the valve cavity between the body, ball and seat. These cavities reduce the chances of residual particle contaminating multiple use line. They are also used in slurry service and process that could solidify if left in closed valve body. These valves are only available in Full Bore construction. These rugged, versatile and high performance ball valves can meet NACE specification.

Areas of application: Chemical / Pharmaceutical / Food /Pharmaceutical / Petrochemical / Energy / Plastics / Oil and Gas / Cement and lubrication

KEY FEATURES:

Cavity free design



The usual cavity between ball and housing in non- cavity free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.

  • Clean, non- false product
  • No sediments of expensive products in the ball valve housing
