Other Information

Technical Details

SANKEY Series 70/90 valves are robust three-piece ball valves in the industry. With advanced seat and seal materials, the Triad rating can be extended to handle service pressures to 250 bar and a temperature 250 Deg C. All features of the standard Sankey Valves are present in the series 70/80 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 an integrally cast top flange designed for ease of actuator mounting.
