Festo
1927027
Non return valve VBNF-LBA-G14-Q8-F1A
This Festo industrial component, part number 1927027, features an unlockable check valve function with pneumatic actuation and a non-detenting manual exhaust function. It operates within a pressure range of 0.02 MPa to 1 MPa (0.2 bar to 10 bar or 2.9 psi to 145 psi) using compressed air as per ISO 8573-1:2010 [7:4:4], and includes a QS-8 pneumatic connection 1, a G1/4 pneumatic connection 2, and a QS-8 pilot air port 21. Built with a PBT housing for screw-in mounting in any position, the unit delivers a standard flow rate 1->2 (6-0) of 1100 l/min and a standard nominal flow rate 1->2 (6-5) of 620 l/min across an ambient temperature range of -10 °C to 60 °C.
