ANSI #150 full port Flanged end connections
Efficient heat transfer
■ Narrow space between extension ID and stem OD allows the stem seal to remain at an ambient temperature.
Stem
■ ‘Blow-out’ proof
■ Solid one-piece stem
■ Tight stem-to-ball engagement
■ High torque durability
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).
