Product Details

Product Details

  • All DSI® forged carbon steel valves maintain a .22% maximum carbon content and are normalized to further refine the grain and homogenize the microstructure.
  • All valves meet NACE conformance.
  • DSI® forged steel valves come standard with a Stellite® #6 seating surface. The Stellite® #6 is applied by an automatic GTAW process, maintaining a minimum thickness of 0.05 inches.
  • 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.
  • 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.
  • 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.
  • DSI® forged steel valves contain no copper bearing alloys.
  • 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.
  • Requires Certification
