Festo
195597
One-way flow control valve GRLA-F-1/8-QS-4-D
The Festo 195597 is a manual one-way flow control industrial component designed for exhaust air with a G1/8 pneumatic connection port and a slotted head screw adjusting element. This threaded valve operates at pressures from 0.2 to 10 bar across an ambient temperature range of 0 to 150 °C, delivering a standard nominal flow rate of 180 l/min in the flow control direction. Weighing 23 g with RoHS conformance and copper- and PTFE-free materials, it utilizes compressed air matching ISO8573-1:2010 [7:4:4] standards and permits lubricated operation.
