Name: Festo 197578 One-way flow control valve GRLA-M5-QS-6-RS-D
Brand: Festo

One-way flow control valve GRLA-M5-QS-6-RS-D

The Festo 197578 is an industrial component featuring an exhaust air flow control non-return function with a QS-6 pneumatic connection 1 and an M5 pneumatic connection 2. It utilizes a knurled screw adjusting element for screw-in mounting, supporting an operating pressure range of 0.2 bar to 10 bar across an ambient temperature range of -10 °C to 60 °C. The unit delivers a standard nominal flow rate of 115 l/min in the flow control direction and 70 l/min to 110 l/min in the non-return direction while operating with compressed air as per ISO 8573-1:2010 [7:4:4].

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.
