Festo
153538
Pressure regulator LR-1/4-QS-8
The Festo 153538 is an industrial component featuring a directly-controlled piston regulator design with a looped-through compressed air supply and a constant output pressure function with secondary exhaust. Constructed with a PBT-reinforced housing, nickel-plated brass threaded plugs, and PTFE threaded seals, this 60 g unit operates within an ambient temperature range of 0 to 60 °C using compressed air in accordance with ISO8573-1:2010 [7:-:-]. It accommodates an inlet pressure of 0 to 9 bar, delivers a pressure regulation range of 1 to 8 bar at a standard nominal flow rate of 101 l/min, and utilizes two QS-8 pneumatic connection ports alongside a threaded mounting type secured by a knurled screw with a lock nut actuator lock in any assembly position.
