About BONOMI

Bonomi is an Italian valve manufacturer with a product range that includes ball valves, butterfly valves, and actuated valve assemblies. The company's catalog covers manual and automated flow-control products used in industrial piping systems. 3G Electric supplies Bonomi valves globally, with stock including stainless steel ball valves, three-way diverting and mixing valves, and electrically actuated ball valves. The product families most commonly specified by plant engineers and maintenance teams include the 956N series three-way T-port ball valves and the M8E series electrically actuated two-way ball valves.

The 956N series is a manual three-way ball valve constructed from CF8M stainless steel, which is the cast equivalent of 316 stainless steel. These valves are available in sizes from 3/8 inch through 2 inches, with FNPT threaded connections on all three ports. The T-port flow configuration allows for diverting flow from a common inlet to either of two outlets, or mixing flow from two inlets into a common outlet. Each valve includes a locking lever handle, which allows the valve to be secured in a given position. The CF8M body material provides corrosion resistance suitable for water, steam, and mildly corrosive media. These valves are typically used in applications where flow needs to be redirected without shutting down the entire system.

The M8E series is an electrically actuated two-way ball valve with a stainless steel body and flange x flange connections. These valves are available in sizes including 2-inch and 3-inch port sizes. The actuator operates on 24V AC/DC and includes a manual override for emergency operation when power is unavailable. The actuator mounting pad conforms to ISO 5211, which is a standard that defines the interface between the valve and the actuator, allowing for interchangeability of actuators from different manufacturers. The IP68 rating indicates that the actuator enclosure is protected against dust ingress and prolonged immersion in water, making it suitable for washdown environments or outdoor installations. These valves are compatible with media including combustible gases, corrosive chemicals, natural gas, steam, and water.

Bonomi valves are used in a range of industrial applications, including chemical processing, water treatment, natural gas distribution, steam systems, and general industrial piping. The stainless steel construction of the 956N and M8E series makes them appropriate for applications where carbon steel valves would corrode. The three-way T-port design of the 956N series is particularly useful in batch processing, where flow must be diverted between different tanks or process lines. The actuated M8E series is used in automated systems where remote or programmed control of flow is required.

3G Electric supports the Bonomi line by maintaining inventory of commonly specified models and providing access to datasheets, technical specifications, and logistics support for global delivery. The product listings include details such as port size, connection type, body material, voltage, IP rating, and compatible media, which allows procurement specialists and engineers to verify that a given valve meets the requirements of their application. For actuated valves, the ISO 5211 mounting pad and manual override are standard features that simplify installation and maintenance. 3G Electric can source additional Bonomi models beyond those listed in the online catalog, subject to availability from the manufacturer.

Frequently asked questions

Common questions about BONOMI from 3G Electric.

What is the difference between the Bonomi 956N series and the M8E series ball valves?

The Bonomi 956N series is a manual three-way ball valve with a T-port flow configuration, CF8M stainless steel body, and FNPT threaded connections. It is operated by a locking lever handle and is used for diverting or mixing flow. The M8E series is an electrically actuated two-way ball valve with a stainless steel body, flange x flange connections, and a 24V AC/DC actuator. It includes a manual override and an ISO 5211 mounting pad. The 956N is for manual flow diversion, while the M8E is for automated on/off or modulating control of flow in a single line.

What media are Bonomi stainless steel ball valves compatible with?

Bonomi stainless steel ball valves, including the 956N and M8E series, are compatible with a range of media. The M8E series is rated for combustible gases, corrosive chemicals, natural gas, steam, and water. The 956N series, with its CF8M (316 stainless steel) body, is suitable for water, steam, and mildly corrosive chemicals. The specific compatibility depends on the valve construction, seat material, and operating conditions. Always verify chemical compatibility with the manufacturer's datasheet for the specific model and application.

What does IP68 mean for the Bonomi M8E actuator?

IP68 is an ingress protection rating defined by IEC 60529. The first digit, 6, indicates that the enclosure is dust-tight. The second digit, 8, indicates that the enclosure is protected against prolonged immersion in water under specified conditions. For the Bonomi M8E series electrically actuated ball valves, the IP68 rating means the actuator can be used in environments where it may be exposed to washdown, rain, or temporary flooding. This makes the M8E suitable for outdoor installations and industrial washdown areas. The rating applies to the actuator enclosure, not the valve body or process connections.

What is the purpose of the ISO 5211 mounting pad on Bonomi actuated valves?

ISO 5211 is an international standard that defines the interface dimensions between a valve and a quarter-turn actuator. This includes the flange size, bolt circle, bolt hole diameter, and stem drive dimensions. The Bonomi M8E series includes an ISO 5211 mounting pad, which allows the actuator to be removed and replaced with another actuator that conforms to the same ISO 5211 size. This standardization simplifies maintenance and allows for flexibility in actuator selection. It also means that if the actuator fails, it can be replaced without replacing the entire valve assembly.

What sizes are available for the Bonomi 956N three-way ball valve?

The Bonomi 956N series three-way T-port ball valve is available in sizes from 3/8 inch to 2 inches. Specific models include 3/8 inch (MPN 956N3/8"), 1/2 inch (956N-1/2"), 3/4 inch (956N-3/4"), 1 inch (956N-1"), 1 1/2 inch (956N-11/2"), and 2 inch (956N-2"). All sizes feature CF8M stainless steel construction, FNPT x FNPT x FNPT connections, and a locking lever handle. The T-port design allows for diverting flow from a common port to either of two other ports, or mixing flow from two ports into a common port.

Can Bonomi M8E valves be used for natural gas service?

Yes, the Bonomi M8E series electrically actuated ball valves are listed as compatible with natural gas, as well as combustible gases, corrosive chemicals, steam, and water. The stainless steel body and flange x flange connections are suitable for gas service. The 24V AC/DC actuator includes a manual override for emergency operation. When specifying for natural gas, ensure that the valve is rated for the operating pressure and temperature of the system, and that all local codes and regulations for gas service are followed. Consult the manufacturer's datasheet for specific pressure and temperature ratings.
