Product Details
- All valves meet NACE conformance
- DSI forged steel valves come standard with a Stellate® #6 seating surface. The Stellate #6 is applied by an automatic GTAW process, maintaining a minimum thickness of 0.05 inches
- All DSI forged carbon steel valves maintain a .22% maximum carbon content and are normalized to further refine the grain and homogenize the microstructure
- DSI forged steel valves contain no copper bearing alloys
- All flanged DSI forged steel valves through class 2500 are integrally forged to avoid the potential leak path that exist when welding flanges onto valve bodies
- Welded bonnet valves are initially joined by threading the body-bonnet joint together, then welding by automatic GMAW. All welds are inspected after welding assuring quality control
- The DSI bolted bonnet and bolted cap valves not utilizing a ring joint connection are fitted with a 316 stainless steel spiral wound Grafoil filled gasket
- Valves are furnished with non-asbestos Grafoil® packing. The top and bottom wiper rings are braided graphite, while the center rings are die-formed Grafoil containing an inorganic passivating inhibitor for corrosion and oxidation resistance
- Every DSI forged steel valve is manufactured with a two-piece self-aligning gland flange assembly which ensures even compression of the stuffing box during assembly and repacking
