Product Highlights
Industries
- Chemicals
- Oil & Gas
- Power
Industry Sectors
- Basic (Organic & Inorganic)
- Specialty (Fine & Consumer)
- Petrochemicals
- Downstream Processing
- Nuclear
- Conventional Steam
- Geothermal
- Combined Cycle
Standards
- ASME B16.34

Design Range
Size Range:
- NPS 1/2 to 4
- DN 15 to 100
Pressure Class Range:
- 1690 to 4500
- PN 290 to 760
Seating Material: Metal
Features and Benefits
- Increased uptime from the use of anti-thrust rings in the body-guided disc, which eliminates misalignment and galling
- Greater process control due to the integral hard-surfaced seat, which allows positive shutoff and seat life
- Enhanced service integrity through an optimum flow shape that minimizes flow direction changes and pressure drops
- Lower operating costs enabled by a die-formed, flexible graphite gasket seated to a prescribed bonnet torque that provides a reliable seal
