Festo
153518
Differential pressure regulator LRL-1/4-QS-10
The Festo part number 153518 is an industrial component featuring a directly controlled piston regulator structural design with a constant differential pressure controller function and a return flow characteristic. Constructed with a reinforced PBT housing, nickel-plated brass screwed plug, and supporting any mounting position, this 43 g unit operates with compressed air per ISO 8573-1:2010 [7:-:-] across an inlet pressure range of 0 bar to 9 bar (0 MPa to 0.9 MPa) and a pressure regulation range of 2 bar to 6 bar. It incorporates an R1/4 pneumatic connection 1, a QS-10 pneumatic connection 2, a counter-locking actuator lock, and a nominal flow rate of 231 l/min in both open and closed states within an ambient temperature range of 0 °C to 60 °C.
