Through Conduit Slab Gate Valve

API 6D Through Conduit Slab Gate Valves

The RANGER Through Conduit Slab gate valves are made to serve petroleum, gas, chemical, water, and slurry applications with an emphasis on reliability, safety, and positive shut-off.

Key Application(s)

  • Pipeline/Transmission lines
  • Tank farms
  • Custody transfer
  • Any application that reliable positive shut-off is required

Design Features

  • Sizes from NPS 2” to 48”(DN50 to DN1200)
  • CLASS 150 to 1500 (PN20 to PN260)
  • Operating temperature -196℃ to 593℃ (the range of service temperature may vary for different materials)
  • A resilient valve seat is supported by the seat carrier to ensure zero leakage
  • the valve seat and the disc surface are hard faced to improve the abrasion resistance and extend the service life of the valve
  • SS+graphite (spiral-wound) or metallic seal (RTJ) or pressure seal bonnet is used to provide a reliable bonnet seal
  • Rising stem position for visual indication of disc position
  • The valve stem thread is isolated from the pipeline media to reduce corrosion
  • Piggable, full-bore design
  • Optional Class A sealing testing available to meet the fugitive emission standard ISO 15848 FE
