Brand: Festo

One-way flow control valve GRLA-3/4-B

The Festo 151180 is an industrial component featuring an exhaust air flow control non-return function with G3/4 pneumatic connections for both ports 1 and 2. It utilizes a slotted screw adjusting element for screw-in mounting in any position, operating within an ambient and medium temperature range of -10 °C to 60 °C and an operating pressure range of 0.3 bar to 10 bar. This unit delivers a standard nominal flow rate of 4320 l/min in the flow control direction and 3220 l/min to 4320 l/min in the non-return direction, while supporting ATEX explosion protection for zones 1, 2, 21, and 22.

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.
