High Pressure Cryogenic Class 2500, full differential pressure for sizes up to and including 2″ (DN50), differential pressure of up to 103 bar (1494 psi) for sizes 2½” (DN65) and above with hybrid seats. Pressure containing parts are in compliance with ASME B16.34, for wall thickness, design type-tested for burst testing of four times the pressure rating for 5 minutes. A one-size-up stem made of high tensile material complies with ASME B16.34 and API 6D for drive train requirements provides a sufficient safety factor during operation. A special hybrid seat design is comprised of a metal housing and polymer insert machined as a single unit provides bubble tight shut-off (Rate A), combined with lower operating torque. 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).
