Valve End Connection Selection

RF, RTJ, BW, SW, threaded, wafer and lug valve end-connection selection for industrial RFQs.

Match the Valve to the Piping Specification

End connection affects dimensions, installation, gasket selection, welding, maintenance and pressure suitability. The valve RFQ should use the same flange or piping basis as the project piping class.

Common Checks

  • Flange standard and class
  • RF or RTJ facing and finish
  • Ring-joint groove / ring type
  • Butt-weld bore and pipe schedule
  • Socket-weld or threaded standard
  • Wafer / lug bolt compatibility
