Definition and standards of Namur valve

Namur valve follow the NAMUR standard, which is an international standard for process control valves developed by the German NAMUR organization. The standard defines the installation dimensions, electrical interfaces and operating specifications of solenoid valves, ensuring that solenoid valves of different brands and models can be used interchangeably. It is known for its precise control and reliability, can withstand a wide range of working pressures, and is widely used in various industrial process controls.

In terms of performance parameters, Namur valve can withstand a wide range of working pressures, from 0.15 to 1 MPa, and have a proof pressure of 1.2 MPa. They are usually made of aluminum alloy materials, do not require lubrication, can operate stably in an operating temperature range of -20 to 70 degrees Celsius, and have a maximum operating frequency of 5 Hz, with a service life of more than 30 million cycles.

Working principle, structure and design of Namur valve

The working principle of Namur valve is based on the electromagnetic force to control the movement of the valve core, thereby realizing the on-off of the fluid. Its structural design is compact, and the internal bore is treated with a special process, which has the characteristics of low resistance, low starting pressure and long service life. In addition, Namur valve also have an internal pilot operation structure, which enables the valve to achieve precise flow control, without lubrication, and simplifies the maintenance process. Namur valve are usually available in 5/2-way, 5/3-way configurations, which means that they can switch between two or three positions and control five different fluid paths. The electrical access method is vertical insertion, suitable for multiple voltage levels such as 12 VDC, 24 VDC, 110 VAC and 220 VAC. These valves are compact, durable and easy to integrate into various automation systems.

Function of Namur valve

Direct installation and control: Namur solenoid valves are designed to be installed directly on the side of pneumatic actuators (such as cylinders) without the need for additional pipe connections. This design simplifies the installation process and reduces the number of connection points, thereby reducing the risk of leakage. At the same time, it makes the control system more compact and improves the reliability and efficiency of the overall system.

Media flow control: Namur valve can reliably control a variety of media flows under very different environmental conditions, whether liquids, bulk goods or gases. In industries such as fine chemicals, pharmaceuticals, water technology or food production, Namur valve can provide stable and reliable control. Its wide range of valve function options and extended temperature range (-20°C to +60°C) enable it to adapt to a variety of complex application scenarios.

Electrical interface and modular design: Namur valve usually have flexible electrical interfaces, which improves their performance and simplifies integration with electrical control systems. In addition, modular design enables Namur valve to quickly adapt to different customer needs, simplify the ordering process, and shorten delivery cycles.

Explosion-proof and safety: Many Namur valve comply with explosion-proof standards such as ATEX and IEC Ex, which enables them to be safely used in potentially explosive environments. This safety is guaranteed by rigorous design and testing, ensuring the stability and reliability of the valve under extreme conditions.

Application scenarios of Namur valve

Industrial automation control system: Precisely control the flow of fluids (such as gases and liquids) to achieve precise control of various industrial automation equipment. For example, in industries such as pharmaceuticals, food and beverage production and storage, water treatment, refineries, and powder feeding, Namur valve are often used in the field of valve actuation.

Fire protection system: Normally closed valves can be used to control water flow to prevent pipeline leakage and flooding. At the same time, the normally open solenoid valve can be used in the water source control of the fire protection system. When the fire protection system fails, the normally open solenoid valve can be automatically opened to ensure the smooth flow of fire protection water.

Medical equipment: Namur valve are also often used to control gas flow or liquid delivery to ensure the safety and stability of medical equipment. For example, in the gas delivery system in medical equipment, Namur valve can accurately control the flow of gas to ensure the normal operation of medical equipment.

Industrial pipeline system: Namur valve are also often used to control flow and pressure. Whether in continuous or intermittent production, Namur valve can provide stable and reliable performance for pipeline systems, helping customers improve production efficiency and reduce operating costs.

Namur valve are also widely used in air conditioning systems, sewage treatment systems, hydraulic systems, pneumatic systems, gas systems and other fields.

Substitution and compatibility of Namur valve

Namur valve have good substitution and compatibility due to their standardized design. They can easily replace other valves that meet NAMUR standards without large-scale modifications to existing systems. In addition, manufacturers of Namur valve usually provide a variety of connection sizes and voltage options to ensure compatibility with different equipment and systems.
