CF3 Body Floating Ball Valve 900lb RTJ Nylon Seat , Two Piece Bolted Construction

Key Features

• Design, manufacture and materials conform to the essential requirements of ISO 17292, ISO 14313, API 608, API 6D, ASME B16.34, ASME VIII and Directives PED 97/23/EC and ATEX 94/9/EC.
• Positive engagement and alignment of 2 piece bolted body providing ‘Gap Free’ connection.
• Fully contained body gasket, graphite seal is protected from the working fluid by primary elastomeric seal for soft seated.
• Superior High Integrity live loaded stem sealing system, double seal before & after fire condition. Standard valve sealing system in compliance with ISO 15848 Class AH, suitable for high vacuum service and technically emission free.
• Cavity pressure relief to high pressure side in the event of thermal expansion of trapped fluid.
• Positive direct pressure relief to upstream side available via vented ball for high volatility duty.
• Modular design, easily adapted for low temperature & cryogenic service or fugitive emission leak detection.
  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
