Features

Design Features

  • Advanced Valve Design for Severe Service Environments: The TRI-CON valve combines precision engineering and advanced materials to provide high reliability in challenging industrial conditions.
  • Triple Offset Geometry: The triple offset design consists of:

    • First Offset – Shaft positioned behind the seat plane to reduce friction.
    • Second Offset – Shaft offset from the pipeline centerline for smooth rotation.
    • Third Offset – A conical seat geometry that enables zero-friction sealing during operation.


    This configuration ensures non-contact operation during opening and closing, dramatically improving valve longevity.

TRI-CON Triple Offset Metal-Seated Butterfly Valves Q & A

+ What is a triple offset butterfly valve and how does it work?

A triple offset butterfly valve uses three geometric offsets in its design to eliminate friction between the valve disc and seat during operation. This design prevents wear on the sealing surfaces and creates a tight metal-to-metal seal when the valve closes. The triple offset geometry ensures longer service life and reliable shutoff in high-temperature and high-pressure industrial applications.

+What are the advantages of metal-seated butterfly valves compared to soft-seated valves?

Metal-seated butterfly valves offer several advantages over soft-seated designs:

  • Higher temperature resistance
  • Greater pressure tolerance
  • Improved durability in abrasive or corrosive environments
  • Longer service life in severe industrial applications

Because of these characteristics, metal-seated valves are commonly used in steam systems, oil and gas processing, and power generation.

+What industries typically use TRI-CON triple offset butterfly valves?

TRI-CON valves are commonly used in industries where high reliability and tight shutoff are critical, including:

  • Power generation
  • Oil and gas refining
  • Chemical processing
  • Petrochemical production
  • Industrial energy systems

These industries often operate with high temperatures, high pressures, or aggressive process media, making triple offset valves an ideal choice.

+ Can TRI-CON butterfly valves be automated?

Yes. TRI-CON valves can be paired with electric, pneumatic, or hydraulic actuators, making them suitable for both manual operation and automated process control systems. Automation allows operators to integrate these valves into modern industrial control systems for remote monitoring and operation.

+ How do triple offset valves improve valve lifespan?

Triple offset valves reduce mechanical wear by ensuring that the disc does not rub against the seat during opening or closing. Contact occurs only at the final moment of sealing. This greatly reduces friction and seat damage, which extends valve life and lowers maintenance costs.

+ How are OVR robots controlled?

OVR robots are typically controlled using Oriental Motor’s MRC Series robot controllers, such as the MRC01 or MRCU integrated controller. These controllers work with AZ Series step-servo motors and can be programmed and tested using MRC Studio software. This integrated ecosystem simplifies setup, programming, and maintenance.
