Festo LR-3/8-D-7-MINI 162584 0.5-7bar G3/8 Die Cast Zinc Directly Actuated Diaphragm Pressure Regulator With Gauge 1800L/min Lockable Rotary Knob

Product Description:

The Festo D Series MINI-class pressure regulators, specifically the LR series, are direct-acting diaphragm pressure regulators engineered to maintain a consistent output pressure. They effectively compensate for fluctuations in input pressure and changes in air consumption within the network, ensuring stable performance.

The "-7" model variants in this series are designed with a pressure regulation range spanning from 0.5 to 7 bar. This makes them particularly suitable for applications that require lower output pressures. These regulators come with threaded port sizes varying from G1/8 to G3/8, providing versatility for different installation requirements.

In terms of performance, these devices offer standard nominal flow rates between 1,000 and 1,800 liters per minute, with operating pressures ranging from 1 to 16 bar. The housing is crafted from robust die-cast zinc, which enhances durability and makes the regulators well-suited for typical industrial environments.

Additionally, the models marked with the "-MPA" suffix include an integrated pressure gauge, allowing for direct and convenient pressure monitoring. Models without this suffix do not have an integrated gauge but still feature two pressure gauge ports, enabling flexible attachment of accessories as needed. Furthermore, all models come equipped with a lockable rotary knob that helps prevent unintended adjustments, ensuring reliable operation.

Features:

This pressure regulator is engineered for applications that require lower output pressures, offering precise control within a range of 0.5 to 7 bar. It ensures consistent performance tailored to low-pressure needs.

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

Equipped with built-in primary pressure compensation and an additional exhaust channel, the regulator maintains effective pressure control even at high flow rates. For system safety, an automatic return valve activates to relieve overpressure conditions.

The device includes a rotary knob with detent and an integrated lock mechanism, preventing accidental changes to the set pressure. This locking feature is standard across all available models.

Two pressure gauge ports offer flexible mounting options. Users can choose front panel installation through accessories or opt for in-line mounting based on their system requirements.

Constructed from die-cast zinc with a corrosion resistance class of CRC 2, the regulator is built to withstand harsh industrial environments, ensuring long-term durability and reliable operation.

This regulator supports various installation methods, including front panel mounting via accessories, direct in-line installation, or positioning in any assembly orientation to suit different setups.

Compatible with compressed air networks ranging from 1 to 16 bar input pressure, the regulator adapts easily to diverse pressure conditions.

The product line offers models with differing nominal flow rates to meet various application needs:

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

The maximum pressure hysteresis is limited to only 0.2 bar, ensuring precise control of the output pressure for sensitive applications.

This regulator can operate with lubricated compressed air. However, once lubricated operation is employed, it must be maintained consistently to ensure performance.

Technical Parameters:

Applications:

Pressure regulation and control are essential in pneumatic systems that demand a lower output pressure range, typically between 0.5 and 7 bar. This is particularly important for delicate pneumatic components and actuators that require precise handling to function optimally without damage.

In automated production lines and assembly systems, maintaining precise and stable pressure control is critical to ensure smooth operation and high-quality output. Such environments rely heavily on accurate pressure management to avoid disruptions and maintain efficiency.

Stabilising the air supply is crucial for pneumatic tools and instruments that operate within a 7 bar output range. Proper regulation guarantees consistent performance and prolongs the lifespan of these tools by preventing pressure fluctuations.

Compressed air preparation and pressure management play a vital role in mechanical engineering and industrial equipment. Effective control systems help maintain optimal conditions for various machinery, enhancing reliability and safety in industrial applications.

In laboratory, testing, and R&D environments, pressure control with inert gases is often required. These settings demand a high degree of accuracy and stability to ensure reliable experimental results and safe handling of sensitive materials.

Some systems need a lockable pressure setting feature that prevents tampering or unauthorized adjustments. This security measure is important to maintain consistent operational parameters and protect the integrity of the process.

Applications where consistent and repeatable pressure is essential—such as precision machining and automated inspection—benefit greatly from advanced pressure regulation techniques. This consistency ensures high accuracy and quality in manufacturing and quality control processes.

Finally, oil-lubricated pneumatic systems, which are compatible with lubricated operation, require specialized pressure control methods to maintain proper lubrication and system performance, ensuring longevity and efficiency of the equipment.

Support and Services:

Our Pneumatic Filter Regulator Lubricator (FRL) units are designed to ensure optimal performance and longevity of your pneumatic systems by providing clean, regulated, and lubricated air supply. For technical support, please ensure that you have the model number, serial number, and relevant system details available when seeking assistance.

Installation: Proper installation of the FRL unit is critical. Install the unit in the correct air flow direction, typically indicated by an arrow on the housing. Ensure the unit is mounted vertically and accessible for maintenance.

Maintenance: Regularly check and replace filter elements to prevent contamination. Drain accumulated water and debris from the filter bowl frequently. Adjust the regulator to maintain the desired output pressure. Refill the lubricator with the recommended type and amount of lubricant to ensure efficient operation of pneumatic tools and components.

Troubleshooting: If you experience pressure drops, check for clogged filters or leaks in the system. Inconsistent lubrication may indicate an empty lubricator bowl or incorrect lubricant type. Address any unusual noises or air flow disruptions by inspecting the unit for damage or blockages.
