Metal-seated, inline-renewable ball valves are available in 0.5 through 4" sizes with socket-weld, butt-weld and flanged ends. Supplied in pressure classes from ASME 900 through 4500, Camseal top-entry forged severe-service ball valves can provide savings in labor, materials and downtime, says the manufacturer. Inline renewability typically is accomplished within 30 minutes. The cartridge is removed for in-situ parts replacement and reassembly. No valve removal, welding and PWHT are required, which is important with F91 valves, the manufacturer notes. The ball valves have zero body, seat and stem leakage on manual and actuated valves.
