NAMUR
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang NAMUR dari 3G Electric.
What does the NAMUR standard refer to in the Bonomi NMR Series solenoid valves?
NAMUR is a standard interface defined by the German organization Normenarbeitsgemeinschaft für Mess- und Regeltechnik in der chemischen Industrie. In the Bonomi NMR Series, it specifies the mounting pattern and port dimensions that allow the solenoid valve to be directly bolted onto pneumatic actuators without additional adapters. This simplifies installation, reduces potential leak paths, and ensures interchangeability across compliant components.
What coil voltages are available for the Bonomi NMR Series solenoid valves?
The Bonomi NMR Series is offered in multiple coil voltages to match common control systems. AC options include 24V, 110V, and 220V. DC options include 12V and 24V. Each valve is labeled with its rated voltage, and the coil is replaceable. Always verify the voltage rating against your control circuit before installation to avoid coil damage.
Are there hazardous-location-rated versions of the Bonomi NMR Series?
Yes, select models in the Bonomi NMR Series carry FM approval for hazardous locations. For example, the NMR3-EX12 is FM Approved for Class III, Division I, Group A environments. These valves are designed with features such as explosion-proof enclosures and sealed coils to prevent ignition of flammable gases or dusts. Check the specific model's approvals and ratings for your application.
What is the difference between conduit connector and DIN solenoid connector options in the NMR Series?
The conduit connector option provides a threaded metal conduit entry for hardwiring the valve to electrical conduit, commonly used in permanent installations requiring robust mechanical protection. The DIN solenoid connector uses a standardized rectangular plug (per EN 175301-803) for quick disconnect and easier maintenance. Both options are available across the NMR Series; choose based on your wiring preference and environmental requirements.
Can the Bonomi NMR Series valves be used with actuators from other manufacturers?
Yes, because the NAMUR interface is a standardized pattern, Bonomi NMR Series valves are compatible with any pneumatic actuator that has a NAMUR mounting pad. This includes actuators from many manufacturers. However, always confirm the actuator's port size and interface dimensions match the valve's specifications (typically 1/4 in NPT) to ensure proper sealing and function.
Does 3G Electric supply NAMUR products?
