Product Overview
The KOZO Orbit Plug Valve is designed for pipeline and process isolation where controlled plug movement, reliable shut-off and reduced sliding contact between sealing surfaces are required. Orbit-style plug valves typically combine lifting and rotational motion so the plug can disengage from the seats before turning.
How the Orbit Mechanism Works
During opening, the plug first moves away from the seats and then rotates to the open position. During closing, it rotates into alignment and is then driven toward the seats. This motion can reduce rubbing compared with conventional plug rotation under full seat contact.
Key Design Features
- Orbit-style plug movement: Controlled disengagement and rotation to reduce seat rubbing.
- Pipeline isolation: Suitable for oil, gas and industrial process service where the selected materials are compatible.
- API 6D / API 599 design family: Reference standards for pipeline and plug-valve configurations.
- RF / RTJ / BW options: Connection styles selected according to pressure class and piping specification.
- Gear or automated operation: Manual and actuator packages can be reviewed according to torque and control requirements.

FAQ
How is an orbit plug valve different from a conventional plug valve?
The orbit mechanism is designed to disengage the plug from the seats before rotation, reducing sliding contact and associated wear.
Can the valve be automated?
Yes. Pneumatic and electric actuator packages can be selected according to torque and plant control philosophy.
