- Main Design Features
- Body Construction: One-piece die forged body, dense structure, high strength, eliminates casting defects, suitable for high temperature and high pressure services
- Bonnet Connection: Bolted bonnet design with 304/flexible graphite spiral wound gasket sealing
- Disc Design: Renewable disc type, hardfaced seating surface for durability
- Stem Design: Backseat feature allows packing replacement under pressure when valve is fully open
- Operating Characteristics: Disc moves linearly along seat centerline, short stroke, reliable shut-off
- Flow Direction: Flow below seat design, reducing operating torque and protecting packing
- Packing: Flexible graphite packing, low emission design
- Seat: Renewable seat rings or integral hardfacing
- Main Component Materials (F11 Material)
