Brand: Festo

One-way flow control valve GRLZ-1/8-QS-4-D

The Festo 193157 is an industrial component featuring a supply air flow control non-return function with a QS-4 pneumatic connection 1 and a G1/8 pneumatic connection 2. This screw-in mountable part utilizes a slotted screw adjusting element, operating across an ambient and medium temperature range of -10 °C to 60 °C with an operating pressure of 0.2 bar to 10 bar. It delivers a standard nominal flow rate of 160 l/min in the flow control direction and 120 l/min to 190 l/min in the non-return direction, utilizing compressed air as per ISO 8573-1:2010 [7:4:4] with optional oil lubrication.

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.
