Product Description:
The Festo D Series MINI-class pressure regulators, specifically the LR series, are direct-acting diaphragm pressure regulators. They are engineered to maintain a consistent output pressure, regardless of fluctuations in supply pressure or changes in air consumption within the system.
The "-7" variants of these regulators offer a pressure regulation range between 0.5 and 7 bar, making them particularly suitable for applications that require lower output pressures. These models come with threaded port sizes that vary from G1/8 up to G3/8, providing flexibility in installation.
These pressure regulators support standard nominal flow rates ranging from 1,000 to 1,800 liters per minute and can operate at pressures from 1 to 16 bar. Their durable die-cast zinc housing ensures they are well-suited for standard industrial environments.
Models identified with the "-MPA" suffix include an integrated pressure gauge for immediate pressure reading. In contrast, models without this suffix do not come with a pressure gauge but still feature two ports for pressure gauge attachments, allowing for adaptable accessory configurations.
Additionally, all models in this series are equipped with a lockable rotary knob. This feature helps prevent accidental adjustments, ensuring reliable and stable pressure regulation.
Features:
The pressure regulator offers an adjustable range from 0.5 to 7 bar, making it ideal for applications that require lower output pressures. This ensures accurate and consistent control within the specified pressure span.
Featuring a direct-acting diaphragm design, the unit exhibits low hysteresis and outstanding regulation performance. These characteristics guarantee stable and precise control over the output pressure, enhancing the reliability of the system.
Equipped with primary pressure compensation and secondary venting, the regulator maintains excellent performance even under high flow conditions. An integrated automatic return valve activates in the event of overpressure, providing an additional layer of safety for the system.
The device includes a lockable rotary knob with detents and an integrated locking mechanism. This prevents unintentional changes to the set pressure, a safety feature included as standard across all models.
Two pressure gauge ports are provided, allowing for versatile installation options. Users can mount pressure gauges on the front panel—using appropriate accessories—or install them in-line, depending on the application requirements.
Constructed from robust die-cast zinc with corrosion resistance rated CRC 2, the housing is designed to withstand demanding industrial environments, ensuring long-lasting durability.
Installation flexibility is another key attribute. The regulator supports front panel mounting (when equipped with suitable accessories), in-line installation, or mounting in virtually any assembly position, accommodating diverse system configurations.
The device operates efficiently across a wide input pressure range of 1 to 16 bar, making it compatible with various compressed air supply networks.
Models with different port sizes provide high flow rates while maintaining low pressure drops: G1/8 versions (LR-1/8-D-7-MINI / -MPA) deliver a standard nominal flow of 1,000 l/min; G1/4 versions (LR-1/4-D-7-MINI / -MPA) provide 1,600 l/min; and G3/8 versions (LR-3/8-D-7-MINI / -MPA) achieve up to 1,800 l/min.
High precision regulation is ensured with a maximum pressure hysteresis of only 0.2 bar, allowing for fine-tuned output pressure control suitable for sensitive applications.
Additionally, the regulator is compatible with lubricated compressed air systems. Once lubricated air is introduced, continuous use with lubricated operation is required to maintain optimal performance.

Applications:
Pressure regulation and control play a vital role in pneumatic systems that demand a lower output pressure range, typically between 0.5 and 7 bar. This level of precision is especially 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 crucial. Such environments rely heavily on consistent pressure to achieve high quality and efficiency in manufacturing processes.
Stabilising the air supply is equally important for pneumatic tools and instruments that operate within the 7 bar pressure range. Consistent air pressure ensures these tools function reliably and safely during various industrial tasks.
Compressed air preparation and effective pressure management are essential in mechanical engineering and industrial equipment applications. Proper handling of air pressure contributes to the efficiency and durability of complex machinery.
In environments such as laboratories, testing facilities, and research and development, pressure control using inert gases is a common requirement. These gases often demand precise regulation to maintain safety and accuracy in experiments and tests.
Certain systems require a lockable pressure setting to prevent tampering or unauthorized adjustments. This feature is particularly valuable in applications where safety and compliance are paramount.
Consistency and repeatability in pressure are indispensable in applications like precision machining and automated inspection. Reliable pressure control ensures that processes are reproducible and meet stringent quality standards.
Additionally, oil-lubricated pneumatic systems benefit from a pressure control solution compatible with lubricated operation, enhancing system performance and reducing maintenance needs.
