Problem solver for high pressure applications


  • Solid, sturdy all metal seat design, based on metal-to-metal contact.
    No resilient components needed for tightness
  • Excellent control and on-off capabilities
  • Design according to API 609 and ASME B16.34, full rated ASME Class 900 to 2500
  • Low emissions according to ISO 15848
  • Certified safety performance, capable to SIL 3 level according to IEC61508
  • Mounting face according to ISO 5211
  • Extremely wide temperature range up to +1150 °C / +2100 °F
  • Fire safe certification according to API 607, 6th edition
  • Wide rangeability in services with low pressure drop
  • Two piece shaft design
  • Industry best valve capacity.


  • Heavy-duty stem and bearings design extends service life and is insensitive to thermal cycles and impurities
  • Extremely high cycle life minimizes the need for maintenance, and increases Mean Time Between Failure (MTBF) value
  • Low cost of ownership
  • Industry smallest operational torque resulting in cost efficient valve package
  • On site interchangeable seat can be replaced without disassembling the disc and shaft. No adjustment or special tools needed
  • Minimized pressure loss and energy costs of the process
  • Consistent performance even in the most difficult, changing process conditions
  • In-built thermal and pressure compensation
  • Industry best valve capacity
  • Shortest possible maintenance hours
