Bonomi ball valves are known throughout the world for their exceptional quality. Solid construction and competitive pricing are all synonymous with the Bonomi name, and those qualities are certainly found in their diverse line of brass, bronze, stainless steel, and lead-free ball valves. The bottom line: Bonomi Valves are quickly becoming known… and this growth is rooted in the Bonomi family’s valve‑making heritage dating back more than a century.
History Behind the Brand Bonomi
From a bronze foundry in Italy, Carlo Bonomi began a company in 1901 that has flourished for seven generations. The company focused its efforts on brass valves soon after operations began, and has continued to do so ever since, repeatedly producing quality products at affordable prices. Today, Bonomi produces a large variety of valves, including several ball valve lines, and is a leader in the world market for technological advancements in ball valves.
Bonomi ball valves are designed and manufactured in Italy by companies within the Bonomi Group and are sold in the United States through Bonomi North America, which operates out of its headquarters in Charlotte, North Carolina.
By bearing in mind trends in international trading, savvy financial management, and consistency in manufacturing standards, Bonomi has remained a well-known name in the valve industry. As all Bonomi products do, Bonomi ball valves undergo thorough validation testing, including double seal testing, with a target of zero leakage and full performance to rated specifications.
Three Types of Bonomi Ball Valves You Want to Check Out
Bonomi 3-Way Valves
The Bonomi 965N and 365N - Stainless Steel and brass (respectively) are 3-way valves with L-port configurations (please refer to T-Port Vs. L-Port), and both feature threaded connections.
The Bonomi 965N Stainless Steel 3-way ball valve is available in sizes 1/2" to 2", features a blowout-proof stem, and operates in a pressure class of up to 1000 psi at 1/2". Its L-port geometry enables a smooth, incremental transition between two distinct flow paths, making it a dependable solution for process piping where corrosion resistance and elevated pressure performance are major factors.
Likewise, the Bonomi 365N is a brass 3-way ball valve alternative to the 965N. It features a blowout-proof stem, chrome-plated brass ball, and is available in sizes 1/4" to 3". The 365N is rated for temperatures of 344 F. This ball valve is particularly well-suited for commercial hydronic systems, compressed air distribution, and light industrial process lines that require multi-port diversion without the necessity of a full stainless steel construction.
Bonomi Actuated Ball Valves
The Bonomi 8E064LF is an electrically actuated brass 2-way ball valve that is lead-free. It features a full port with threaded connections and is available in 1/4" to 2". Its multi-voltage AC/DC electric actuator supports flexible integration into very diverse electrical control circuits. The Bonomi 8E064LF is an excellent automated option for commercial plumbing, municipal water processing, and general fluid automation where lead-free materials are strictly mandated.
The Bonomi 8P0080 is a pneumatically operated double-acting lead-free brass 2-way ball valve. It features a fail-in-place position, ensuring that upon loss of air pressure or control signal, the valve retains its last operational position. The Bonomi 8P0080 also has a blowout-proof brass stem and a chrome-plated brass ball. Sizes range from 1/4" to 4". And it's rated for a max pressure of 600 WOG (Water, Oil, Gas) and 150 WSP (Working Steam Pressure). These valves work well for municipal potable water mains, industrial washdown circuits, and HVAC fluid handling.
The Bonomi 8P0141 is a Stainless Steel 3-way T-port ball valve with a spring-return actuator. This valve features RTFE seats, threaded connections, and a 316 Stainless Steel ball. Available in sizes 1/2" to 3". The Bonomi 8P0141 handles high-pressure service up to 1000 PSI (at 1/2") and utilizes reinforced PTFE (RTFE) seats to preserve tight sealing and chemical endurance under continuous thermal cycling. It is powered by a spring-return pneumatic actuator that automatically forces the valve into a fail-safe position upon loss of supply air, providing a robust solution for automated chemical processing, aggressive media routing, and critical safety loops.
Bonomi Manual Ball Valves
The Bonomi 171N is a brass 2-way ball valve featuring a full port, threaded connections, and chrome-plated brass ball. Operated via a sturdy steel lever handle with a protective vinyl grip, the Bonomi 171N is a dependable standard for non-potable commercial heating, chilled water networks, and utility air systems.
The Bonomi 1970LF is a lead-free brass 2-way ball valve featuring a full port, Euro-press connections, chrome-plated brass ball, and blowout-proof stem. Complete with a durable steel lever handle, the Bonomi 1970LF is designed for fast deployment in residential and commercial potable water distribution systems, institutional plumbing retrofits, and domestic hot water lines.
The Bonomi 1715 is a brass 2-way ball valve with chrome-plated brass ball, brass stem and steel handle; features full port and solder connections. The Bonomi 1715 is widely utilized in conventional copper hydronic heating systems, non-potable domestic piping, and commercial mechanical systems where sweat connections are preferred.
