SPECIAL VALVES FOR TOXIC SERVICES

 
Designed and manufactured to eliminate fugitive emissions and to handle the toughest services such as:
The stuffing box design with all the positive shutt-off, corrosion resisting features of other Weir BDK PTFE Sleeve Plug Valves
Many options such as bonnet tap for insertion of Chlorine compatible lubricant or other greases, for inert gas pad, or as a leak-off connection.
           
 

Hydrofluoric Acid
Chlorine

Anhydrous HCI

Will accommodate all standard Packing.

           

3 Way plug configurations are available as options.
