Floating Ball Valve Side Entry Split Body – Low Temperature

Floating Ball Valve Side Entry Split Body – Low Temperature

Model no. VFC-VFE

Valves suitable for Gas (LNG, LPG, Condensate and other marketable fractions) processing, dehydration, refrigeration, liquefaction, storage, transportation and distribution, also suitable for chemical and petrochemical refining.

Floating Ball Valve Side Entry Split Body – Low temperature

 

GENERAL CONSTRUCTION
 

Floating ball valves have the obturator free from axial constraints and it is supported between two soft seat inserts; under pressure the ball compresses the downstream soft insert to obtain the sealing; these valves are generally recommended for use in clean service with limited sizes and ratings. Erreesse production range offers a wide selection of models and construction suitable for critical services also. VFC model is suitable for low temperature applications where internal body cavity relief by seat design is required.

 

MATERIALS OF CONSTRUCTION
  • Low Temperature and Low Alloy Carbon Steel
  • Stainless steel, Duplex and Super Duplex
  • Nickel alloys
  • Titanium
  • Bronze
