Festo
195599
One-way flow control valve GRLA-F-1/8-QS-8-D
The Festo 195599 is a manual one-way flow control valve featuring a G1/8 pneumatic connection port and a slotted head screw adjusting element for exhaust air regulation. Weighing 23 g with a nominal tightening torque of 3 Nm (± 10 %), this threaded component operates across a temperature range of 0 to 150 °C and an operating pressure range of 0.2 to 10 bar using ISO8573-1:2010 [7:4:4] compressed air. It delivers a standard nominal flow rate of 275 l/min in the flow control direction and 132 to 307 l/min in the non-return direction, while being constructed RoHS-compliant and free of copper and PTFE.
