API 6D Through Conduit Slab Gate Valves

API 6D Through Conduit Slab Gate Valves are full port valve,design and test acc to API 6D,running  functions of double & bi-directional sealing and reinforced mechanical sealing.Our API 6D expanding gate valve is for Oil & Gas field services, drilling, pipeline transportation, distribution, and storage.

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
