BOB

BOB is a manufacturer of float valves, float balls, and related components for liquid level control in industrial, commercial, and agricultural applications. The brand is known for its focus on mechanical float valve assemblies, repair parts, and accessories designed for water and other compatible media. BOB's product line includes general service float valve assemblies, float valve bodies, rods, stems, disc and cup kits, plunger kits, and polypropylene threaded floats. These components are used in applications such as tank filling, reservoir level maintenance, and process water management. BOB float valves are typically constructed with materials like brass, stainless steel, and polypropylene, offering corrosion resistance and durability in various environments. The valves feature angle valve bodies, adjustable arms, and threaded connections (FNPT or MNPT) for horizontal piping installations. Flow rates vary by model, with examples such as 58 gpm at 85 psi for the R1350 series and 112 gpm at 35 psi for the R1380 series. Rods and stems are available in stainless steel with 1/4"-20 or 3/8"-16 threading, in lengths such as 10 inches and 12 inches. Repair kits, including disc and cup kits and plunger kits, are designed for specific BOB valve models like R1350-1/2, R1350-3/4, R1350-3/8, and R1360-3/4, enabling maintenance and extended service life. BOB components are also NSF-certified where indicated, supporting use in potable water systems. 3G Electric supplies a range of BOB products, including 71 SKUs, with datasheets and logistics support for global procurement. This allows plant engineers, maintenance managers, and procurement specialists to source BOB float valves and repair parts for new installations or replacement needs. The availability of individual components—such as stems, floats, and repair kits—facilitates targeted repairs without replacing entire assemblies, reducing downtime and inventory costs.
