API 6D Twin Seal Orbit plug valve featuring Double Block & Bleed (DBB). Reduced bore design for industrial oil & gas applications requiring positive isolation. Class 150-900, NPS 2-36.
Orbit mechanism lifts plug before rotating, eliminating sealing surface friction and wear.
Provides verifiable positive isolation through true Double Block and Bleed (DBB) functionality.
Designed for long service life and low operating torque due to non-contact opening/closing action.
Features dual independent sealing (elastic primary, metal-to-metal secondary fire-safe backup).
Allows for potential in-line maintenance (seal replacement) typically via bottom entry access.
Reduced bore configuration suitable for various pipeline system requirements.
Manufactured and tested according to API 6D and API 598 standards for reliability.
