WAFER BALL VALVE
SANKEY wafer ball valves are ideally suited to applications where space is at a premiumprovide plus all the benefits of flanged ball valve while reducing the cost and weight. The valve can be installed between flanges with help of bolts.
Our wafer ball valve is normally one-piece design and floating ball type, and are available in both cast and forged construction in sizes ranging from DN15 to DN 100, in #150 to #900 pressure rating.

The usual cavity between ball and housing in non- cavity free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.
Push Fit Insert design
Because of the further distance from the actuator mounting flange to the vessel, it makes the automation of the ball valve and isolation of the vessel very convenient.
Fire-safe tested and approved
SANKEY Wafer ball valves of the WF series have been tested successfully per British Standard BS 6755 and API-607.The material utilized for the soft seals in "fire-safe" valves remains dependent upon the required chemical resistance to suit the fluid, the application and operation conditions.
When fire does break out, it is important that it does not spread through failures in pipe-work systems. Even under the most extreme conditions shut-off valves provide :
