In the Beginning
Beginning in New York City as a small specialty manufacturer servicing the valve industry, Mueller Steam Specialty incorporated in 1956 to start manufacturing pipeline strainers. Since then, the company and its product offering have expanded dramatically. The company moved to North Carolina in 1972 and due to its continued growth, moved again in 1992 to a new and larger facility in St. Pauls, North Carolina. There are now over 300,000 square feet of ISO 9001:2000 registered manufacturing space devoted to Mueller’s various product lines. In addition to a full range of pipeline and specialty strainers, the company now manufactures a broad offering of check valves and butterfly valves.
Mueller Joins the Watts Family
In December 2005, Mueller became a part of the Watts Water Technologies, Inc. family of companies. The resources and support that Watts has added to Mueller have enabled the company to consolidate previous efforts while at the same time plan for future growth and expansion in products and services.

As always, Mueller Steam Specialty brand strainers and valves will continue to be the premier products of their kind in the marketplace.

Our Screens & Baskets are Designed to Achieve Maximum Straining Efficiency
The most critical aspect to any strainer is straining efficiency and durability. Mueller Steam Specialty's many years of experience and continuous improvements provide the highest quality. We carry a larger inventory of perforated metals and meshes than any other strainer manufacturer in the world. Besides standard metals, we carry thousands of variations of materials and openings. Openings range from 1" to 5 microns.
BASKET TYPE STRAINERS
Mueller Steam Specialty Simplex Basket Strainers are called for when the application requires a strainer with an extremely large capacity. Most of these strainers have an open area ratio of 6 to 1 with even greater open area ratios available. As with all of the Mueller Steam Specialty strainers, basket strainers are available in an almost endless combination of materials, pressures, end connections and cover confi gurations from 1/4" to 24" (72" in fabricated units). Units are also available in cast iron, bronze, carbon steel, stainless steel, Alloy 20 and most other alloys. The baskets in the Mueller Steam Specialty simplex basket strainers share the same quality of construction as the Mueller Steam "Y" strainers. From threaded end connections to offset fl anged connections, we can provide the exact basket strainer to meet your needs.
DUPLEX STRAINERS
Many times, critical systems cannot be shut down for strainer basket cleaning. These systems include cooling water, compressors, condensers, fire lines, fuel lines, chemical process systems, pump suction applications and other similar services. For these applications, the Mueller Steam Specialty Duplex Strainer is the perfect choice. For sizes 3/4" through 6", the Revolutionary Ball-Plex™ duplex strainer from Mueller Steam Specialty has all of the features you need. Bubble tight seating, true in-line maintainability, extremely easy seat replacement and long, trouble-free service life in a very simple and rugged design.
All of the Ball-Plex™ units are standard with 316 SS balls and PTFE seats. Other alloys are also available for the balls. Threaded and flanged units are available with full rated pressures from Class 125 to Class 300 (Class 600 flanges also available). With the floating ball design and relatively low torque requirements, it is very easy to automate these units for remote operation.
