Nordstrom Valves

Sven Nordstrom invented the first lubricated plug valve in 1914. Since then the Nordstrom Valve Company has successfully filed over 90 patents covering virtually every improvement to lubricated plug valves. Today Nordstrom’s lubricated plug valve manufacturing plant in Sulphur Springs, Texas is the largest in the world.

Nordstrom's widespread acceptance and long-time usage is a tribute to the versatility, proven performance and rugged durability of the Nordstrom plug valve design. It also demonstrates the effectiveness of  the many improvements that have resulted from Nordstrom’s continuing advances in valve design, materials application engineering and production technology which has upgraded valve performance while maintaining competitive pricing. Obviously, a great many users agree that the Nordstrom plug valve offers the best value for money on the market today!

At Nordstrom, high technological effort has been and continues to be dedicated to providing one of the valve industry’s most outstanding research, development and test capabilities, as well as advanced manufacturing systems. Nordstrom’s broadening investment in product research and development activities, computer aided design
systems, experimental and qualification testing facilities, new production techniques and state-of-the-art equipment and plant facilities has resulted in greater efficiencies and cost savings in the design and production of the Nordstrom plug valve.

The company offers a full range of sizes, full service, proven performance and a name that stands for quality. Its products include iron and steel lubricated tapered plug valves, polyethylene ball valves, Pressure Class to ANSI Class 150 up to 2500, valve sealants and sealant equipment

The Dynamic Balance valve is the premier Flowserve Nordstrom plug valve, incorporating proven features and user benefits with over sixty years of experience in endless valve applications and design technology. A pressure-balanced plug assures predictable torque, even under high pressure differential, vibration and thermal cycling. Pressure energized stem seals eliminate external adjustments and the stem and the cover weatherseal provides superior corrosion resistance in hostile environments.

The Dynamic Balance plug valve is available in the broadest range of sizes, pressure classes, and materials of construction of any Flowserve Nordstrom Valves product. Dynamic Balance valves are available in sizes from 1" to 30" in ASME pressure classes from 150 to 2500, and in sizes 21⁄16 to 41⁄16 in API 3000 and 5000 psi.

The Super Nordstrom steel plug valve complements the Dynamic Balance plug valve line, offering the benefits of predictable low torque, at a competitive price, in a limited range of smaller sizes (1/2" to 4") and lower pressure classes up to 600# for less critical and less demanding services.

Product range includes:

• Dynamic and Pressure Balanced Plug Valves1 to 30" in ANSI Class 150 to 2500.
• Iron Plug Valves in Short, Regular and Venturi patterns up to 800CWP
