Nordstrom steel plug valve

The Flowserve Super Nordstrom plug valve carries on the Nordstrom tradition of valving excellence. Complementing the broad line of Dynamic Balance plug valves, the Super Nordstrom valve offers dependable, bubble-tight shut-off and predictable torque in an economical line of valves in a smaller size range (1/2 through 4) for low to medium pressure (ANSI classes 150, 300 and 600).

The Super Nordstrom design features a stainless steel spring that is compressed between the small end of the plug and body. This applies a constant force to the plug, tending to lift it out of the taper. This movement of the plug, however, is limited by stainless steel controlled-dimension washers located between the large end of the plug and cover. The “controlled-balance” effect is maintained by the spring pressure at the small end of the plug and the controlled dimension washers at the large end.

Extensive testing – not to mention years of experience with Dynamic Balance plug valves – has shown that this precisely controlled vertical lifting of the plug eliminates wedging of the plug in the body taper without affecting tight shut-off. The plug is permanently adjusted at plant assembly by selection of the proper washers – thereby eliminating the need for field readjustment.
