Product Description:
The Festo D Series MINI-class pressure regulators, known as the LR series, are direct-acting diaphragm pressure regulators engineered to maintain a stable output pressure. They effectively compensate for fluctuations in input pressure and varying air consumption within the network.
The "-7" variants of these regulators offer a pressure regulation range from 0.5 to 7 bar, making them particularly suitable for applications that require lower output pressures. They come with threaded port sizes ranging between G1/8 and G3/8, providing flexibility in installation options.
These devices deliver nominal flow rates between 1,000 and 1,800 liters per minute, while supporting operating pressures that range from 1 to 16 bar. Their sturdy die-cast zinc housing ensures durability and makes them well-suited for standard industrial settings.
Models carrying the "-MPA" designation include an integrated pressure gauge, allowing for direct and convenient pressure monitoring. Conversely, models without the "-MPA" suffix do not include a pressure gauge but maintain two pressure gauge ports to allow for flexible accessory attachment.
Furthermore, all the models are equipped with a lockable rotary knob, which helps to prevent unintended adjustments, enhancing operational safety and reliability.
Features:
The pressure regulator is engineered to operate efficiently within a range of 0.5 to 7 bar, making it ideal for applications that demand precise control at lower output pressures. This allows users to maintain accurate pressure levels tailored to their specific requirements.
Featuring a direct-acting diaphragm design, the regulator ensures low hysteresis along with excellent regulation characteristics. This design guarantees stable and precise control over the output pressure, enhancing overall system performance.
Incorporated within the device is a primary pressure compensation mechanism complemented by secondary venting. This combination supports reliable regulation even under high flow conditions. Additionally, an automatic return valve activates to relieve overpressure, thereby safeguarding the system.
The unit includes a lockable rotary knob equipped with a detent and an integrated locking function. This secure adjustment feature prevents any accidental changes to the set pressure and comes as a standard on all available models.
For versatile installation and monitoring, two pressure gauge ports are provided. These allow for flexible mounting options, such as front panel installation using accessories or direct in-line placement within the system.
Constructed from durable die-cast zinc with a corrosion resistance class of CRC 2, the regulator is built to withstand harsh industrial environments. This robust metal housing ensures long-term reliability and protection against corrosion.
The device supports flexible installation methods, including front panel mounting through accessories, in-line installation, or positioning in any assembly orientation, offering adaptability to various system setups.
Compatibility with a wide operating pressure range is ensured, accepting input pressures from 1 to 16 bar. This makes the regulator suitable for various compressed air networks and industrial applications.
High flow rates are achieved with minimal pressure drop across different model sizes:
- G1/8 models (LR-1/8-D-7-MINI / -MPA): nominal flow rate of 1,000 l/min
- G1/4 models (LR-1/4-D-7-MINI / -MPA): nominal flow rate of 1,600 l/min
- G3/8 models (LR-3/8-D-7-MINI / -MPA): nominal flow rate of 1,800 l/min
The regulator maintains high precision in pressure regulation, featuring a maximum pressure hysteresis as low as 0.2 bar. This ensures consistent and accurate output pressure control throughout operation.
Additionally, the regulator is compatible with lubricated compressed air. Once operating with lubrication, it is required to maintain such lubricated conditions to preserve system functionality and performance.

Applications:
Pressure regulation and control are vital in pneumatic systems that demand a lower output pressure range, typically between 0.5 and 7 bar. This is especially important for protecting sensitive pneumatic components and actuators, ensuring their optimal performance and longevity.
In automated production lines and assembly systems, achieving precise and stable pressure control is crucial. Such control guarantees the efficiency and reliability of operations dependent on consistent pneumatic pressure.
It is equally important to stabilize the air supply for pneumatic tools and instruments operating within a 7 bar output range. Consistent pressure helps maintain the accuracy and effectiveness of these tools in various industrial tasks.
In the realm of mechanical engineering and industrial equipment, the preparation of compressed air and management of pressure play a significant role. Proper pressure control supports the smooth functioning and durability of such machinery.
For laboratory, testing, and research & development environments, pressure control using inert gases is essential. This ensures safety and precision when handling sensitive experiments or processes.
Certain systems require a lockable pressure setting to prevent tampering or unauthorized adjustments. This feature helps maintain system integrity and prevents accidental or deliberate changes that could disrupt operation.
Applications demanding consistent and repeatable pressure, such as precision machining and automated inspection, benefit greatly from reliable pressure regulation. Such consistency is key to achieving high-quality results and maintaining process standards.
Additionally, oil-lubricated pneumatic systems are compatible with these pressure control techniques, supporting lubricated operation without compromising performance.
