ZURN WILKINS
Frequently asked questions
Common questions about ZURN WILKINS from 3G Electric.
What types of backflow preventers does ZURN WILKINS offer?
ZURN WILKINS manufactures several categories of backflow preventers, including double check assemblies (e.g., 350XL, 350), reduced-pressure zone assemblies (e.g., 950XLTDA), and pressure vacuum breakers (e.g., 1-710). These are available in pipe sizes from 3/4 inch to 2 inches and larger, with connection options such as FNPT and flanged. Materials include bronze and ductile iron, and shut-off valve types vary from ball valves to OSY gate valves depending on the model.
Are ZURN WILKINS water pressure regulators low-lead compliant?
Many ZURN WILKINS water pressure regulators, such as the 34-20XLDULU and 212-500XLFC, are specified as low-lead compliant. This means they meet the requirements of lead-free laws for potable water systems, typically limiting lead content to less than 0.25% in wetted surfaces. Always verify the specific model's compliance status via the datasheet, as not all variants may carry this designation.
What is the maximum operating temperature for ZURN WILKINS pressure regulators?
Standard capacity water pressure regulators from ZURN WILKINS, like the 34-20XLDULU, have a maximum operating temperature of 140°F. This rating applies to models with bronze bodies and FNPT connections. For higher temperature applications, consult the product datasheet for specific model limits, as automatic control valves or other variants may have different thermal tolerances.
What connection types are available for ZURN WILKINS backflow preventers?
ZURN WILKINS backflow preventers are offered with FNPT (female national pipe thread) and flanged connections. For example, the 350XL model is available in FNPT x FNPT, while the 1-350 uses flange x flange connections. The choice depends on pipe material and installation requirements. FNPT is common for smaller sizes (up to 2 inches), while flanged connections are used for larger diameters or where ease of maintenance is needed.
Can ZURN WILKINS automatic control valves be used for pressure reducing applications?
Yes, ZURN WILKINS automatic control valves, such as the 3-ZW209, function as pressure reducing valves. They are designed to maintain a set downstream pressure regardless of upstream fluctuations. The 3-ZW209 operates within a 15 psi to 120 psi range and features a ductile iron body with flanged connections, suitable for larger pipe sizes (e.g., 3 inches) in commercial or industrial water systems.
