Technical Details

SANKEY Series 90 valves are robust two-piece ball valves in the industry. With advanced seat and seal materials, the Triad rating can be extended to handle service pressures to 450 bars and a temperature 250 Deg C.

All features of the standard Sankey Valves are present in the series 90 design including a heavy robust center section tapped for full hex head cap screws, Tertiary stem sealing design, body seals, anti-static protection and locking safety handles. As with most SANKEY valve designs, our valve comes standard with a top flange designed for ease of actuator mounting.
