Design features
• 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
• Narrow space between extension ID and stem OD allows the stem seal to remain at an ambient temperature.
No trapped cavity
• Relief hole on the upstream sphere of the ball to prevent pressure build-up in the cavity.
Flexible bonnet installation angle
• Up to 45° from vertical for 12” bonnet (per BS6364 guidelines)
• Up to 15° from vertical 6” bonnet (not BS6364 compliant).
