Festo
195811
One-way flow control valve GRXA-1/8-QS-6-D
The Festo part number 195811 is a one-way flow control valve designed for exhaust air featuring a G1/8 pneumatic connection port and a slotted head screw adjusting element for threaded mounting. Operating with a working pressure of 0.2 to 10 bar within an ambient and medium temperature range of -10 to 60 °C, this 26 g component accommodates filtered compressed air with a 40 µm filtration level using either lubricated or unlubricated media. Its construction incorporates a wrought aluminum alloy screw-in stud, NBR seals, a POM release ring, a brass regulating screw, and a chromed zinc die-casting swivel joint to deliver a standard nominal flow rate of 185 l/min in the flow control direction and 160 to 240 l/min in the non-return direction.
