Description

Orbital ball valve-(1)

The Orbit Ball Valve, or Orbital Ball Valve, is uniquely engineered to eliminate seal rubbing through its tilt-and-turn core movement, offering superior durability and precise shut-off in demanding applications such as oil and gas processing, petrochemical, refinery, and power generation systems. As a typical orbit ball valve, it separates the closing motion into lift, rotate, and cam-driven sealing stages, enabling the core to disengage from the seat before rotation and re-seat with axial force on final closure—delivering frictionless operation and reduced torque requirements

The orbit ball valve uses a fixed single-seat design that seals in both flow directions and avoids trapped pressure within the body, enhancing safety and reliability. Made from forged or cast carbon steel, stainless steel, duplex, or high nickel alloys, this valve supports pressure classes from ASME 150 to 2500 and temperatures from –196 °C (with cryogenic trim) up to 600 °C or even 650 °C depending on seat material—perfect for both cryogenic and high-temperature applications

A key advantage of the metal-seated orbit ball valve is its consistent bubble-tight sealing even under extreme thermal or erosive conditions. The metal seating and cam mechanism press the core onto the seat without sliding contact, drastically reducing wear and extending service life. Its self-cleaning core surface allows uniform flow circulation, washing away deposits on the sealing surface before final closure to prevent clogging .

Operation is easy with low torque via manual handwheel, worm gear, pneumatic, hydraulic, or electric actuator options. The low-torque orbit ball valve mechanism leverages guide pins and spiral stem grooves to perform accurate lift-turn-close motion while minimizing force on seat surfaces—making it ideal for tight-seal applications without heavy actuation. Its top-entry body design supports inline maintenance, allowing inspection or replacement of internal parts without depressurizing the pipeline

This industrial orbit ball valve is often chosen in critical isolation use cases such as emergency shutdown, meter isolation loops, flowline bypass, and switching operations in high-pressure gas or liquid systems. It meets standards such as API 6D, ASME B16.34, ISO 14313, ISO 17292, and fire-safe certifications (API 607/6FA), along with low-emission packing per ISO 15848 for fugitive emission control

Engineers value the orbit ball valve for its long service life, superior sealing, ease of in‑place maintenance, and ability to resist wear in abrasive or corrosive media. When leakage prevention and reliable isolation are critical, this valve offers both the performance of a globe valve and the low operating torque of a ball valve—all in one rugged package.
