Festo Flow Regulator

The Festo LRL-1/8-QS-4 differential pressure regulator with R1/8 inlet port and push in 4mm tube outlet port is made of nickel plated brass. The housing is made of PBT-reinforced material. The differential pressure regulator maintains a manually adjusted differential pressure between the primary pressure at the screw-in thread and the output pressure at the QS push-in connector. Pressure applied at the QS push-in connector can be exhausted with no change in pressure at the thread connection end thanks to an integrated non-return valve.
