Festo Type LR Pressure Regulator

Pressure regulator is used to reduce the pressure of compressed air, regulate and lower the higher inlet pressure to the outlet pressure that meets the usage pressure, and maintain the stability of the regulated outlet pressure. Festo type LR pressure regulator is a manually adjustable direct acting ordinary diaphragm structure air regulator. Can be combined with filters and lubricator to form an FRL unit.

The LR pressure regulator has a relatively simple structure and is commonly used in cost sensitive and functionally simple applications. Usage of air regulator: Pull up to unlock, rotate to adjust pressure, press down to lock

Festo type LR pressure regulator  Maintenance

1. It is recommended to assign a dedicated person to be responsible for operation and maintenance.

2.Regular maintenance 1-2 times a year is the best method for reliable operation and longevity of pressure reducing valves. The following four situations inside the solenoid valve are the reasons that hinder its normal operation and shorten its lifespan.

(1) Changes in the medium during use

(2) The intake air inside the takeover rusted and fluctuated greatly.

(3) The oil oxidation of the air compressor produces impurities such as carbon particles and tar, which mix into the pipeline

(4) There are too many impurities in the pipeline.

3.Before maintenance, it is necessary to cut off the gas source and remove the pressure

4. When disassembling the pressure reducing valve for cleaning, kerosene or other solutions can be used, but attention should be paid to the possibility of rubber components swelling, so they need to be replaced.

5. After disassembling and cleaning, various components should be restored to their original state in order and installed.

6. OLK pneumatic company's spare vulnerable parts, please specify when ordering if needed

FAQ:

When to use a non-relieving pressure regulator?

When the medium is harmful gas (e.g., coal gas), choose a regulator without a relief port to prevent leakage and workplace contamination.

What type is the FESTO LR regulator?

The LR regulator is a direct-acting, standard type pressure regulator.

what is Similarities and differences between FESTO LR and MS regulators:

Similarities:

Both are direct-acting, diaphragm-type pressure regulators.

Differences:

LR: Simple structure, compact size, fixed mounting style.

MS: High modularity, multiple port directions, more accessory options, higher expandability. Suitable for flexible configuration and high-performance industrial applications.
