Emerson added the Fisher Z500 model to its range of sever on/off 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) provides excellent corrosion resistance and helps to eliminate the problems associated with severe service conditions.
Lever-operated Fisher Z500 valves have a contact-proof stem adapter designed to prevent the stem from being knocked into the ball, causing misalignment and possible leakage.
