Wafer Type Ball Valves ( Series 50 )
 
WAFER BALL VALVE  
SANKEY wafer ball valves are ideally suited to applications where space is at a premium provide 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.

Key Features  

ADVANTAGES : SANKEY Wafer Ball Valve

 

Cavity free

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.
› Clean, non- false product
› No sediments of expensive products in the ball valve housing
 
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.

  • Easy maintenance, quick dismantling, assembly thus fast turnaround time for the valve.   
  • Low torque design
  • Avoids unnecessary load on the seat and seals
   

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:

ƒ• Secure Operation         ƒ
ƒ• Reliable Sealing in shut-off position              ƒ
ĥ Reliable Sealing to the outside
