Special mechanical design and construction

  • Solid one-piece high torque durable stem.
  • Tight stem-to-ball directional engagement, ensures relief hole alignment.
  • Strict materials and manufacturing tolerances control.

Efficient heat transfer

  • A narrow space between the extension ID and the stem OD allows the
    stem seal to remain at an ambient temperature.

No-Trap Cavity

  • Relief hole on the upstream sphere of the ball to prevent pressure buildup in the cavity.
  • Single-side or self-pressure-relief sealing for bidirectional full pressure service.

Flexible bonnet installation angle

  • Up to 45° from the vertical axis for the 12” bonnet (per BS6364 guidelines).
  • Up to 15° from the vertical axis for the 6” bonnet (not BS6364 compliant).

Flow direction indicators (for valves with preferred flow direction)

  • Highly visible arrows on body and bonnet top.
  • “T” mark on the stem, showing relief hole direction.
