Festo LR-3/8-D-7-MINI-MPA 8002290 Zinc Alloy Pressure Regulator G3/8 0.5-7bar With MPA Gauge

Product Description:

The Festo D Series MINI-class pressure regulators, specifically the LR series, are direct-acting diaphragm pressure regulators engineered to ensure a stable output pressure. They effectively maintain consistent pressure despite fluctuations or changes in air consumption within the network.

The "-7" models within this series offer a pressure regulation range between 0.5 and 7 bar, making them particularly suitable for applications that demand lower output pressures. These regulators come with threaded port sizes from G1/8 up to G3/8, catering to a variety of installation requirements.

Delivering standard nominal flow rates between 1,000 and 1,800 liters per minute, the LR series operates efficiently at pressures ranging from 1 to 16 bar. Their casing is made of robust die-cast zinc, which ensures durability and suitability for typical industrial settings.

Variants labeled with the "-MPA" suffix include an integrated pressure gauge, allowing for direct and convenient pressure monitoring. In contrast, models without the "-MPA" designation do not come with a pressure gauge but still provide two ports for attaching gauges or other accessories as needed. Additionally, all regulators are equipped with a lockable rotary knob to prevent unintentional adjustments.

Features:

This pressure regulator is specifically engineered for applications that demand lower output pressures. It provides precise control within the range of 0.5 to 7 bar, ensuring accurate and consistent pressure delivery to meet your specific needs.

Featuring a direct-acting diaphragm design, the regulator exhibits low hysteresis and excellent regulation characteristics. This design guarantees stable and precise control of the output pressure, enhancing the reliability of your system.

Equipped with built-in primary pressure compensation and a secondary exhaust channel, the regulator maintains excellent regulation even under high flow rates. Additionally, an automatic return valve activates in case of overpressure, providing an essential safety mechanism for your system.

The rotary knob includes a detent and integrated lock feature that prevents accidental changes to the set pressure. This security function is included as standard on all available models, ensuring stability in pressure settings.

With two pressure gauge connections, this regulator offers versatile mounting options. Pressure gauges can be installed either on the front panel using accessories or mounted in-line, providing flexibility in setup configurations.

Constructed from die-cast zinc with a corrosion resistance class (CRC) of 2, the housing is designed for durability and long service life, even in harsh industrial environments.

The regulator supports multiple installation methods including front panel mounting (via accessories), in-line installation, or positioning in any desired assembly orientation, making it adaptable to various system layouts.

Compatible with a broad input pressure range from 1 to 16 bar, this regulator can be integrated with a variety of compressed air networks.

• G1/8 models (LR-1/8-D-7-MINI / -MPA): Standard nominal flow rate of 1,000 l/min
• G1/4 models (LR-1/4-D-7-MINI / -MPA): Standard nominal flow rate of 1,600 l/min
• G3/8 models (LR-3/8-D-7-MINI / -MPA): Standard nominal flow rate of 1,800 l/min

The regulator boasts a maximum pressure hysteresis as low as 0.2 bar, ensuring extremely precise output pressure control for sensitive applications.

This device is compatible with lubricated compressed air systems. Once lubricated operation has been initiated, it must be maintained to guarantee optimal performance and longevity.

Technical Parameters:

Applications:

Pressure regulation and control are essential in pneumatic systems that require a lower output pressure range, typically between 0.5 and 7 bar. This is particularly important for protecting sensitive pneumatic components and actuators, ensuring their optimal performance and longevity.

In automated production lines and assembly systems, maintaining precise and stable pressure control is critical. Accurate pressure regulation contributes to the reliability and efficiency of these operations, where consistent performance is key to meeting production standards.

Stabilizing the air supply for pneumatic tools and instruments operating within the 7 bar output range is another crucial application. Proper pressure management enhances tool effectiveness and prevents damage caused by pressure fluctuations.

Compressed air preparation and pressure management play a vital role in mechanical engineering and various industrial equipment. These processes ensure that pneumatic systems operate smoothly and safely under the required pressure conditions.

Additionally, pressure control with inert gases is frequently used in laboratory, testing, and research and development environments. Such careful regulation is necessary to achieve accurate and repeatable results in scientific and technical applications.

Certain systems demand a lockable pressure setting to prevent tampering or unauthorized adjustments. This feature helps maintain system integrity and guarantees that the set pressure values remain consistent during operation.

Applications that require consistent and repeatable pressure, such as precision machining and automated inspection, rely heavily on reliable pressure regulation. Ensuring stable pressure is fundamental to achieving high-quality outcomes in these fields.

Finally, oil-lubricated pneumatic systems benefit from pressure control solutions that are compatible with lubricated operation, enabling smooth functionality and extending the service life of system components.
