Hub End Check Valve

Design Features

  • Design to API 6D and Face to Face Distance as per manufacturer’s standards.
  • Hub Ends are available on Dual Plate Check Valve as well as Non Slam Axial Flow Check Valves.
  • Hub connections are used on Offshore and sub sea pipelines, where weight is a major design criteria.
  • Hub End Valves being lighter, saves weights – saves money, as compared to ANSI Flanged End Valves.
  • Hub Clamp are generally selected by the customer being proprietary design of Techlok, Grayloc and Vector Hub Clamp, Flovel will design and end connection suitably.
  • Clamp connections uses 4 bolts hence quick connection and installation as compared to ANSI Flanged End valves.
  • Clamp connection ensures proper clamping force resulting in no leakage during bending and vibrations which generally occurs in long pipelines.
  • Seal Ring profile is precisely machined using CNC machines and special inserts.
