G1/4 1600L/min Die Cast Zinc Festo LR-1/4-D-7-MINI-MPA 8002289 Pressure Regulator 0.5-7bar Directly Actuated Diaphragm With MPA Gauge Lockable Knob

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

The "-7" models in this series offer a pressure regulation range from 0.5 to 7 bar, making them particularly suitable for applications that require lower output pressures. These regulators are available with threaded port sizes varying from G1/8 up to G3/8.

With standard nominal flow rates ranging between 1,000 and 1,800 liters per minute and operating pressures from 1 to 16 bar, these regulators are versatile for various industrial needs. Their durable die-cast zinc housing ensures they can withstand typical industrial environments.

Additionally, models marked with the "-MPA" suffix come with an integrated pressure gauge, allowing for direct and convenient pressure monitoring. In contrast, models without this suffix do not include a pressure gauge but retain two gauge ports for optional accessory installation.

All variants in this series are equipped with a lockable rotary knob, which helps prevent unintended adjustments, ensuring reliable and consistent operation.

The pressure regulator offers a regulation range from 0.5 to 7 bar, making it ideal for applications that require lower output pressures. This ensures precise and reliable control within this specific range.

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

The device incorporates primary pressure compensation coupled with secondary venting. It includes built-in primary pressure compensation and a secondary exhaust channel, which maintains good regulation performance at high flow rates. Additionally, an automatic return valve activates in case of overpressure, enhancing system safety.

Equipped with a lockable rotary knob, the regulator prevents accidental pressure adjustments. The knob features detents and an integrated lock mechanism, a standard element on all available models.

Two pressure gauge ports are provided to facilitate flexible installation options. These include front panel mounting via accessories or direct in-line installation, offering adaptability to various setups.

Constructed with a robust die-cast zinc housing, the regulator boasts a corrosion resistance class CRC 2. This durable metal construction ensures long-lasting performance even in harsh industrial environments.

Installation is highly versatile, supporting front panel mounting (with accessories), in-line installation, or any desired assembly position. This flexibility allows for easy integration into different systems.

The regulator supports a wide operating input pressure range from 1 to 16 bar, making it compatible with various compressed air networks.

It delivers high flow rates with minimal pressure drop across three model sizes:

• 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

High precision regulation is ensured by a maximum pressure hysteresis as low as 0.2 bar, allowing for precise control of output pressure.

The regulator is compatible with lubricated compressed air systems. Once lubricated operation has been initiated, it must be maintained throughout use for optimal performance.

Pressure regulation and control are essential in pneumatic systems that demand a lower output pressure range, specifically between 0.5 and 7 bar. This level of precision is particularly important for safeguarding sensitive pneumatic components and actuators, ensuring their optimal performance and longevity.

In automated production lines and assembly systems, maintaining precise and stable pressure control plays a crucial role. These environments rely heavily on consistent pressure to guarantee smooth operation and high-quality output throughout the manufacturing process.

Stabilising the air supply is vital for pneumatic tools and instruments that operate within the 7 bar output range. Proper pressure management ensures these tools function reliably and efficiently, minimizing downtime and maintenance needs.

Effective compressed air preparation and pressure management are also key factors in mechanical engineering and industrial equipment. These measures help maintain system integrity and performance, supporting complex machinery in demanding industrial settings.

In laboratory, testing, and research and development environments, pressure control using inert gases is often required. Such applications benefit from precise regulation to maintain safety, accuracy, and repeatability during experimental and analytical procedures.

Some systems necessitate a lockable pressure setting to prevent tampering or unauthorized adjustments. This feature is critical in maintaining predetermined pressure levels, safeguarding system reliability, and ensuring compliance with operational standards.

Applications demanding consistent and repeatable pressure, such as precision machining and automated inspection processes, depend heavily on reliable pressure control. This consistency is key to achieving high-quality results and maintaining tight tolerances.

Lastly, oil-lubricated pneumatic systems require compatibility with lubricated operation. Proper pressure regulation in these systems supports smooth functionality and extends the life of lubricated components.
