Name: Festo 161404 One-way flow control valve CRGRLA-1/8-B
Brand: Festo

One-way flow control valve CRGRLA-1/8-B

The Festo 161404 is a one-way flow control industrial component featuring G1/8 pneumatic connections on both ports and a manual actuation type with a slotted screw adjusting element for screw-in mounting. This valve operates within a pressure range of 0.03 MPa to 1 MPa (0.3 bar to 10 bar / 4.35 psi to 145 psi) and an ambient temperature range of -20 °C to 80 °C, delivering a standard nominal flow rate of 340 l/min in the flow control direction and 260 l/min to 420 l/min in the non-return direction. It uses compressed air as per ISO 8573-1:2010 [7:4:4], permits oil lubrication operation, complies with VDMA24364-B2-L LABS conformity, and is suitable for the production of Li-ion batteries with reduced Cu/Zn/Ni values (F1a) with ATEX explosion prevention 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
