Festo
1927030
One-way flow control valve VFOF-LE-BAH-G14-Q8
The Festo 1927030 is an industrial component featuring an exhaust air flow control non-return function combined with a piloted check valve and a non-detenting manual exhaust function. It is equipped with a QS-8 pneumatic connection 1, a G1/4 pneumatic connection 2, a QS-8 pilot air port 21, an internal hex adjusting element, and screw-in mounting capability for installation in any position. This part delivers a standard nominal flow rate of 590 l/min in the flow control direction and 310 l/min to 540 l/min in the non-return direction across an operating pressure range of 0.02 MPa to 1 MPa (0.2 bar to 10 bar / 2.9 psi to 145 psi). Constructed with a PBT housing and ATEX certification for Zone 2 and Zone 22 explosion prevention, it operates within an ambient temperature range of -10 °C to 60 °C using a pilot pressure of 0.2 MPa to 1 MPa (2 bar to 10 bar / 29 psi to 145 psi).

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.
