Riverhawk's custom design steam valve covers achieve uniform load distribution for proper gasket seating. In our Gimpel case study, we found that by replacing original hydraulic torque wrenching tools with Riverhawk custom designed external tensioners, 17" long studs are hydraulically stretched to achieve a residual 30,000 psi stud stress after relaxation. With Riverhawk’s custom steam valves, accurate preload, and reduced turnaround time, is achieved with uniform pressure distribution.
Give us a call and our experienced engineers will help you customize a steam valve cover to suit your individual needs.
