BOB

BOB is a manufacturer of float valves and related repair components used in liquid-level regulation across industrial, commercial, and municipal systems. The product line centers on float valve assemblies and a structured repair-parts program, with model families designated by R-series numbers such as R1350, R1351, R1360, R1361, R1370, R1371, R1380, and R1381. These models are available in multiple port sizes, including 3/8 in, 1/2 in, 3/4 in, 1 in, 1-1/4 in, 1-1/2 in, and 2 in, allowing selection based on flow capacity and connection requirements. The valves are typically constructed with bodies, arms, floats, plungers, discs, and cups that can be serviced individually rather than replacing the entire assembly. This modular design supports maintenance programs where wear parts are stocked and replaced as needed. BOB repair kits are organized by function: plunger kits (KS200, KS210, KS240, KS250), arm kits (KS300, KS310, KS320), and disc-and-cup kits (KS110). Each kit maps to specific valve models and part numbers, simplifying identification and ordering. For example, the KS200 plunger kit fits model R1360-3/4, while the KS320 arm kit covers R1380 and R1381 models in 1-1/4 in, 1-1/2 in, and 2 in sizes. The disc-and-cup kit KS110 is compatible with R1351 and R1361 models in 3/8 in, 1/2 in, and 3/4 in sizes. These kits restore sealing and flow control in float valve assemblies, extending service life and reducing downtime. 3G Electric supplies the BOB line as part of its industrial equipment catalog, offering 71 SKUs that include complete float valve assemblies, replacement bodies, floats, and repair kits. The catalog covers the full range of BOB model numbers and their corresponding part numbers, such as 23MJ69 through 23MJ77, which are referenced in compatibility lists. Technical buyers can cross-reference manufacturer model numbers and part numbers to select the correct replacement components. 3G Electric ships globally, serving plant engineers, maintenance managers, and procurement specialists who require documented compatibility and consistent specifications. The BOB product family is suited to applications where reliable liquid-level control is needed, including water treatment, cooling systems, process tanks, and irrigation. The valves operate based on mechanical float action, with the float position directly controlling the plunger or disc to open or close the flow path. This simple mechanism is well understood by maintenance teams and does not require external power. The availability of individual repair kits means that common wear items can be replaced without specialized tools, provided the correct kit is selected for the valve model. 3G Electric maintains inventory of these SKUs to support both new installations and ongoing maintenance. For procurement, the key considerations are the valve model number, port size, and the specific repair kit required. The compatibility lists provided in the product data help ensure that the correct part is ordered. BOB float valves and repair kits are available through 3G Electric's global distribution network, with product data structured to support technical evaluation and quoting.

Frequently asked questions

Common questions about BOB from 3G Electric.

What is the difference between a BOB plunger kit and an arm kit?

A BOB plunger kit replaces the plunger assembly that seals against the valve seat to control flow. It is used when the plunger or its sealing surface is worn, causing leakage or poor shutoff. An arm kit replaces the lever arm that connects the float to the plunger or disc mechanism. It is used when the arm is bent, corroded, or damaged, affecting the float's ability to actuate the valve. Both are repair parts for BOB float valves and are model-specific. For example, the KS200 plunger kit fits model R1360-3/4, while the KS300 arm kit also fits R1360-3/4. Selection depends on the worn component.

Which BOB float valve models are compatible with the KS110 disc and cup kit?

The BOB KS110 disc and cup kit is compatible with float valve models R1351-1/2, R1351-3/4, R1351-3/8, and R1361-3/4. It is also referenced with part numbers 23MJ69 through 23MJ76. This kit replaces the disc and cup components that form the sealing element in these valves. It is used when the disc or cup is worn, causing leakage or loss of flow control. The kit is specific to these models and sizes; other BOB models may require different repair kits. Always verify the valve model number before ordering.

What sizes are available in the BOB R1380 float valve series?

The BOB R1380 float valve series includes models with port sizes of 1-1/4 in, 1-1/2 in, and 2 in. These are designated as R1380-1 1/4, R1380-1 1/2, and R1380-2. The series is part of the larger BOB float valve range and shares repair kits with related models. For instance, the KS320 arm kit is compatible with R1380-1 1/4, R1380-1 1/2, R1380-2, as well as R1381-1 1/4, R1381-1 1/2, and R1381-2. The R1380 series is typically used in higher-flow applications where larger port sizes are required.

How do I identify the correct BOB repair kit for my float valve?

To identify the correct BOB repair kit, first locate the model number on the valve body or nameplate. BOB float valves use R-series model numbers such as R1350, R1351, R1360, R1361, R1370, R1371, R1380, and R1381, often followed by a size designation. Then determine which component needs replacement: plunger, arm, or disc and cup. Match the model number to the compatibility list for each kit. For example, the KS240 plunger kit fits R1380-1-1/4, while the KS310 arm kit fits R1370-1 and R1371-1. Part numbers like 23MJ69 through 23MJ77 may also be referenced. If uncertain, consult the product data or contact 3G Electric for assistance.

Are BOB float valves suitable for both water and other liquids?

BOB float valves are primarily used for water and similar liquids in liquid-level regulation systems. The materials of construction determine compatibility with specific fluids. Standard models are typically used in water treatment, cooling systems, and process tanks where the liquid is compatible with the valve materials. For aggressive or non-water fluids, verify chemical compatibility with the wetted materials. BOB does not publish a universal fluid compatibility list in the provided data, so selection should be based on the specific application requirements and material resistance. 3G Electric can provide product data to support evaluation.

What is the function of the BOB KS320 arm kit?

The BOB KS320 arm kit is a replacement arm assembly for float valves. It connects the float to the valve mechanism, transmitting the float's vertical movement to open or close the valve. The kit is compatible with BOB models R1380-1 1/2, R1380-1 1/4, R1380-2, R1381-1 1/2, R1381-1 1/4, and R1381-2. It is used when the original arm is damaged, bent, or corroded, which can prevent proper valve actuation. The kit includes the necessary components to restore the arm function. It is a repair part, not a complete valve assembly.
