  • NPS 2 1/2" to 36" (ASME)

Pressure Class Range:

  • PN 16 to 160 (DIN)
  • Class 150 to 900 (ASME)

Seating Material: Metal or soft seated


Features & Benefits
  • Long service life in severe applications owing to chemical coating and high-performance cladding
  • Reliability ensured by seat design to FCI 70-2 Class VI, enabling it to meet the highest demands with zero tightness
  • Reduced replacement cost as performance capabilities of valves can be easily upgraded and coatings can be applied to suit different applications
  • Improved plant and personnel safety from valve design, which meets fugitive emission standard ISO 15848

Extreme High Cycle
Stem supported in bearings to ensure seals are free from operation loads. Special bearing configurations, including cladding of critical areas and trim coating configurations, improve valve life-time.

Extreme High Temperature
Designed for temperatures up to +1022°F for the highest demands on valve tightness in process and to atmosphere (FE).

Solid Transport
Chambered ball seats, seat pocket body design, stem seal protection and flushing system designs support valve performance and extend service life-time.

Severe Service
Process optimized coatings, cladding option and wearing protection feature for extended ball valve life-time.

Flushing Systems
Flushing options in critical valve areas (e.g., on seats, stem or cavity) avoid media build up to improve service-life time.

Oxygen Service
High performance designs for high pressure, metal to metal seat gas tightness solutions in oxygen service. In-house clean-room assembly and testing.

Special Alloys
Process and application related special alloys (e.g., Inconel, Monel, Alloy20, Titanium)

Special Applications
Product discharge valves, valve internal cladding for critical areas in abrasive and erosive environment, and ESD (Emerging Shut Down valves) units.
