Forged-Steel

All DSI® forged carbon steel valves maintain a .22% maximum carbon content and are normalized to further refine the grain and homogenize the microstructure.
Every DSI Forged Steel valve is NACE compliant.
Gland Packing: Die-formed Graphite Rings with Braided Graphite Top and Bottom Wiper Rings.
All flanged DSI forged steel valves are integrally forged.
Bonnet designs included bolted, union and welded construction.
Bellow Seal and Cryohenic forged valves available.
DSI forged steel valves contain no copper bearing alloys.
