- Main Design Features
- بناء الجسم: One-piece die forged body, dense structure, high strength, eliminates casting defects
- Bonnet Connection: Bolted bonnet design with 316/Flexible Graphite spiral wound gasket sealing
- Disc Design: Renewable disc type, hardfaced seating surface
- 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
- Seat Design: Metal-to-metal seating or STL hardfacing for durability
- Packing: Flexible graphite packing, low emission design
- Main Component Materials (A105N Material)
