JBT Series Trunnion Type Soft Seat Ball Valve

JBT Series Trunnion Type Soft Seat Ball Valve

Trunnion Type Soft – Metal Seat Ball Valve

ASME CLASS 150 – CLASS 300 – CLASS 600 – CLASS 900 – CLASS 1500 – CLASS 2500

The JBT & JBTM Series are Trunnion-mounted ball valves designed with vanguard engineering and highly sophisticated technology. Our in-house High Velocity Oxygen Fuel-sprayed hard faces allow them to defy the toughest operating conditions, such as high pressure, abrasive and corrosive mediums, slurries, etc. Successfully used in the Oil & Gas industry, Refineries and Power Plants, these API 6D certificated valves provide an outstanding tightness, stability, safety and reliability that exceed most industry standards.

Product features

  1. True bidirectional design and wide temperature range satisfying all applications.
  2. Cavity pressure relief design protecting against any excess of pressure in the body cavity.
  3. Trunnion ball design ensuring a tight contact between seats and balls, and allowing the valves to withstand extremely high pressures.
  4. Single Piston seat rings that guarantees the self-relief of the body cavity in case of overpressure.
  5. Double piston design in option, securing both upstream and downstream sealings.
  6. Optional double block and bleed design ensuring a safe isolation simultaneously on both upstream and downstream seats.
  7. Splined stem design strengthening the trim to withstand heavy torques under high pressure drops.
  8. Emergency sealant injection design on request to restore the seat or packing integrity immediately.
  9. Optional drain plug device to empty the cavity or to detect any leakage.
  10. Body gland providing a trustworthy anti-blowout function and an easy maintenance.
  11. Several alternatives of soft and metal seats to meet any kinds of requirement.
  12. Optional purge device guaranteeing a complete cleaning of the body cavity.
  13. Fire safe design according to API 607 or API 6FA.
  14. Anti-static device.
  15. ISO 5211 Mounting Pad design.
