- Main Design Features
- Body Construction: One-piece forged body, dense structure, high strength, eliminates casting defects .
- Bonnet Connection: Bolted bonnet design with spiral wound gasket sealing .
- Disc Design: Renewable disc type, hardfaced seating surface or integral seat.
- 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.
