Frequently asked questions
Common questions about WILKINS from 3G Electric.
What materials are used in WILKINS water pressure regulators?
WILKINS water pressure regulators are constructed from materials such as cast bronze, brass, and stainless steel, depending on the model. For example, the 112-NR3XLDULU uses cast bronze, while the 1-600XL3DU and 2-600XL3 are made of brass. The 375ST backflow preventer features stainless steel. These materials are selected for corrosion resistance and durability in water systems. Many models are low-lead compliant, meeting standards for potable water applications.
What is the pressure range for WILKINS pressure reducing valves like the 1-600XL3DU?
The WILKINS 1-600XL3DU pressure reducing valve operates within a pressure range of 15 psi to 75 psi. This range is typical for standard-capacity regulators in the 600XL series, which are designed for residential, commercial, and industrial water systems. The valve adjusts downstream pressure to a set point within this range, protecting equipment from excessive pressure. Always verify the specific model's datasheet for exact settings and tolerances.
Are WILKINS backflow preventers like the 975XL2 suitable for high-temperature applications?
The WILKINS 975XL2 backflow preventer is rated for operating temperatures from 33°F to 180°F, making it suitable for cold and hot water systems within that range. It is a reduced pressure principle (RPZ) device designed to prevent backflow in cross-connection situations. For applications exceeding 180°F, consult the manufacturer's specifications for alternative models or materials.
What repair kits are available for WILKINS valves?
WILKINS offers repair kits such as the RK2-720A, which includes a washer and lower disc for the 720A valve model, and the RK14-975XLR, a rubber repair kit with checks for the 975XL2 series backflow preventer. These kits are designed for specific valve models and sizes, with the RK14-975XLR compatible with valve sizes from 1/4 inch to 1/2 inch. They enable maintenance of sealing and flow control without replacing the entire valve assembly.
What connection types are available for WILKINS pressure regulators?
WILKINS pressure regulators typically use FNPT (female national pipe thread) connections, as seen in models like the 112-NR3XLDULU and 1-600XL3DU. Pipe sizes range from 3/8 inch to 2 inches. Some models offer union types, such as single union (e.g., 2-600XLHLR) or no union (e.g., 112-NR3XLDULU), which affect installation flexibility and ease of maintenance.
