*For cryogenic temperatures down to -196°C, pressure rating remains at the 100°F rating (2160 psig) per ASME B16.34.*

Test Pressures (Per API 598):

  • Shell Test: 4500 psig (Hydrostatic)
  • Seat Test (High Pressure): 3240 psig (Hydrostatic)
  • Seat Test (Low Pressure): 60 psig (Pneumatic)
  • Cryogenic Test: Per BS 6364 at -196°C (Optional requirement)
  1. Product Features
  1. Cryogenic Design: Extended bonnet prevents ice formation on stem packing and ensures reliable operation at -196°C.
  2. Floating Ball Design: Provides tight shut-off under high pressure; ball is free to move slightly to press against the downstream seat.
  3. RTJ Flanged Ends: Ring-Type Joint connection ensures leak-tight sealing in high-pressure and high-temperature cycling services.
  4. Fire-Safe Design: Compliant with API 607, secondary metal-to-metal seat contact in case of seat fire damage.
  5. Anti-Static Device: Spring-loaded plunger dissipates static charge across ball and stem to body, preventing spark ignition.
  6. Low Fugitive Emissions: Live-loaded packing system (Belleville washers) maintains constant compression on stem seals.
  7. Full Bore (Optional): Unrestricted flow passage for minimal pressure drop (if specified).
  8. Material Traceability: All pressure-containing parts are fully traceable to mill test reports.
  1. Testing & Inspection
  • Visual Examination: Per MSS SP-55
  • Dimensional Check: Per ASME B16.10 & B16.5
  • Hydrostatic Shell Test: 1.5 x 900LB rating at ambient temperature (as per API 598)
  • Hydrostatic Seat Test: 1.1 x 900LB rating (high pressure)
  • Low Pressure Pneumatic Seat Test: 60 psig air
  • Cryogenic Test (Optional): Per BS 6364: at -196°C, cycling test with helium leak detection (leak rate ≤ 100 mm³/s)
  • Non-Destructive Examination (Optional): PT/RT on castings, UT on forged bodies if required.
