Product Description
The Festo LRL-1/8-QS-4 series flow regulator is a high-precision pneumatic function fitting designed for industrial applications requiring reliable pressure regulation. With an inlet male thread of R 1/8 inch G and a QS-4 tube outlet connection, it enables seamless integration into pneumatic systems.
Manufactured with a reinforced Polybutylene Terephthalate (PBT) housing and a nickel plated brass threaded plug, this regulator offers robust durability and corrosion resistance. It maintains a manually adjustable differential pressure between the screw-in thread and QS push-in connector output, ensuring consistent flow rates.
The flow regulator can operate safely within a maximum pressure of 9 bar and withstand ambient temperatures from 0°C up to 60°C. Its knurled screw and lock nut actuator provide secure adjustment without loss of settings during operation.
The push-in connector supports tubing with outer diameters from 4mm to 12mm and can be rotated a full 360 degrees for versatile installation configurations. A PTFE threaded seal ensures leak-tight connections, and an integrated non-return valve prevents backflow, protecting system integrity.
This component meets RoHS standards, ensuring environmentally compliant manufacturing. Although it does not have hazardous area certification, it is suitable for demanding environments such as aerospace, mining, medical fields, and compressed air systems.
The regulator maintains differential pressure for precise flow control. Nickel plated brass threaded plug enhances durability. Reinforced polybutylene terephthalate housing for strength. Supports inlet pressure up to 9 bar and temperature up to 60°C.
360° rotatable push-in fitting for flexible tubing connection. Knurled screw with lock nut provides adjustment security. Integrated non-return valve prevents reverse flow. Compliant with RoHS environmental standards.
