One-way flow control valve GRLA-1/8-QS-3-RS-D

The Festo part number 197579 is an industrial component featuring an exhaust air flow control non-return function with a QS-3 pneumatic connection on port one and a G1/8 connection on port two. It utilizes a knurled screw adjusting element for screw-in mounting, delivering a standard nominal flow rate of 130 l/min in the flow control direction and 100 l/min to 130 l/min in the non-return direction across an operating pressure range of 0.2 bar to 10 bar. Designed for compressed air media according to ISO 8573-1:2010 [7:4:4] with a nominal tightening torque of 3 Nm, this component operates within an ambient and medium temperature range of -10 °C to 60 °C in any mounting position.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
