Fisher Z500 Severe Service Ball Valves

The Fisher Z500 severe service ball valve is a simplistic, two-piece floating ball design with an integral metal seat that provides tight shutoff in high temperature, high pressure, and erosive applications. The mate-lapped ball and seat constructions help ensure sealing. The high-velocity oxyfuel coatings (HVOF) provide excellent corrosion resistance and help eliminate the problems associated with severe service conditions.

Features

  • Integral 90 degree lockplate design prevents over-rotation and maintains critical alignment on lever-operated valves.
  • The side-mounted bracket helps prevent stem and packing box side load and bolt stress loads by attaching to the side of the valve body.
  • Packing design utilizes live-loaded spring washers for easy adjustment.
  • Lever-operated valves have a contact-proof stem adapter designed to prevent the stem from being knocked into the ball, causing misalignment and possible leakage.
  • Rugged, one-piece, machined, surface-hardened, and polished stem is designed to be blow-out proof.
  • Preferred sealing seat is machined into the end adapter, coated, and mate-lapped with the ball.
  • Full metal construction for an inherently fire-safe design.
  • The high-velocity oxyfuel coating (HVOF) forms a very hard and dense coating on the base metal of the ball forming a strong mechanical bond.
