Industry Sectors
- Basic (Organic & Inorganic)
- Specialty (Fine & Consumer)
- Petrochemicals
- Downstream Processing
- Nuclear
- Conventional Steam
- Geothermal
- Combined Cycle
Standards
ASME B16.34
ASME Section III
Design Range
Size Range: NPS 1/2 to 2
DN 15 to 50
Pressure Class Range: 600 to 1500
PN 110 to 260
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 integral hard-surfaced seat, which allows positive shutoff and seat life
- Lower maintenance costs due to bolted bonnet, four-bolt design
- Longer service life from positive metal to metal stop design that prevents over-compression of the gasket
- High-performance delivered through optimization of flow passages to minimize flow direction changes and reduce pressure drops
