Floating Ball Valve Side Entry Split Body

Floating Ball Valve Side Entry Split Body

Model no. VF2 – VF3 – VF8 – VF9

Valves suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining.

 

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.

 

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