Bonomi Solenoid Valves
One of the contributing factors to Bonomi's solenoid success lies in product compatibility: Bonomi solenoid valves mount seamlessly to ALL Bonomi actuated ball valve packages, which adds unparalleled versatility to their actuated valve packages. In addition to this adaptability, these solenoid valves demonstrate remarkable simplicity and dependability in their design. The following models, including Bonomi's NMR1 line, will exemplify Bonomi's commitment to excellence in solenoid valve performance.
Bonomi NMR1, 4-Way Explosion Proof NAMUR Solenoid Valve:
Certified for NEMA 4, 4.X, 7, and 9*, this 4-way pilot valve controls double-acting pneumatic actuators and a Cv of 1.68. It features 1/4" NPT conduit connections, 100% continuous duty cycle, 20 to 120 psig operating pressure, and a temperature range of 35°F to 130°F (0°F to 130°F for dry air). And the power consumption is just 2.5 W. This solenoid valve features one supply port, two work ports leading to the actuator, and two exhaust ports. [NEMA 4/4X/7/9; Class I, Zone 1; Ex m II T4; AEx m II; approved for hazardous locations: Class I, Division 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III]
Bonomi NMR1, 4-Way Conduit Solenoid Valve:
With low power consumption at only 2.5 watts, this conduit solenoid valve shares identical operating numbers with the aforementioned valve: pressure and temperature ranges, as is Cv. Porting are the same, as well as a 100% duty cycle. Ports are clearly marked for fast, easy installations. Generous amount of wire lead for solid connections and is rated NEMA 4/4X for washdown/harsh outdoor environments.
Bonomi NMR3 Series 3-Way Watertight NAMUR Solenoid Valve:
The Bonomi NMR3 series is rated NEMA 4/4X for washdown and harsh outdoor environments. This 3-way pilot valve is engineered for spring-return (single-acting) pneumatic actuators. Features a high flow coefficient (Cv = 1.68), 1/2" NPT conduit electrical entry, 1/4" NPT air ports, and low power consumption (2.5 Watts). Includes one inlet port, one outlet port, and one exhaust port.
Bonomi NMR1 Series 4-Way DIN Connector Solenoid:
Utilizes a standard Form B DIN plug (IP65) for fast plug-and-play wiring connections. Operating on 2.5W low-power coils with a Cv of 1.68, this single-solenoid NAMUR valve controls double-acting actuators in non-hazardous industrial applications. It's rated NEMA 4/4X.
Conclusion
These Bonomi solenoid valves are the culmination of decades of research and experience. Manufactured and tested to the highest standards, Bonomi solenoid valves are competitively priced, easy to install, and built for long, reliable service. It's easy to see why Bonomi solenoids are becoming fierce contenders in the solenoid market. You can also shop for other incredible solenoids from leading manufacturers such as ASCO.

Bonomi Solenoid Valve FAQs
What is a NAMUR solenoid valve, and why does the mounting standard matter?
NAMUR is a standardized mounting pattern that lets a solenoid valve bolt directly onto a pneumatic actuator without extra brackets or tubing. Because Bonomi's solenoids share this footprint, they mount seamlessly to every Bonomi actuated ball valve package, simplifying specification and reducing installation time and leak points from separate fittings.
What's the difference between Bonomi's 4-way and 3-way NMR solenoid models?
The 4-way NMR1 models (explosion-proof, standard conduit, and DIN connector versions) are built for double-acting actuators, using one supply port, two work ports to the actuator, and two exhaust ports to alternately pressurize and vent both sides. The 3-way NMR3 model instead serves spring-return (single-acting) actuators with a simpler one inlet, one outlet, one exhaust configuration, since only one side of the actuator needs active air routing while a spring drives the return stroke.
What operating conditions can these solenoid valves handle?
All four featured NMR models share the same core performance envelope: a Cv of 1.68, 20 to 120 psig operating pressure, and 2.5 watts power consumption for continuous duty. The standard temperature range runs 35°F to 130°F, extending down to 0°F when using dry air, matching independently listed Bonomi NAMUR valve specs from other distributors.
Is there a version rated for hazardous or explosive environments?
Yes. The NMR1 4-Way Explosion Proof model carries hazardous-location approvals including NEMA 4/4X/7/9, Class I Zone 1, Ex m II T4, and AEx m II, plus Class I Division 1 Groups A–D, Class II Groups E–G, and Class III certification. This makes it suitable for oil and gas, chemical processing, or other environments with flammable vapors or dust, whereas the standard conduit and DIN-connector NMR1 models are rated NEMA 4/4X for washdown and harsh outdoor use but not certified for explosive atmospheres.
What electrical connection options are available, and how do they differ?
Bonomi offers three wiring styles across the NMR1 line: a 1/4" NPT conduit connection (standard and explosion-proof versions), a wire-lead version with generous lead length for direct hardwiring, and a Form B DIN plug (IP65-rated) for quick plug-and-play connections. The conduit and DIN versions suit non-hazardous industrial and washdown settings, while the explosion-proof conduit model is the only one certified for hazardous locations.
