Name: Festo 8068743 One-way flow control valve VFOE-LS-T-M5-Q4
Brand: Festo

One-way flow control valve VFOE-LS-T-M5-Q4

The Festo 8068743 is an industrial component featuring a supply air flow control non-return function with a QS-4 pneumatic connection 1 and an M5 pneumatic connection 2. It utilizes a manual actuation type with a rotary knob with latch adjusting element, screw-in mounting, and a PBT housing material rated for an ambient temperature range of -10 °C to 60 °C. This unit operates within a pressure range of 0.02 MPa to 1 MPa (0.2 bar to 10 bar, 2.9 psi to 145 psi) using compressed air as per ISO 8573-1:2010 [7:4:4], supporting ATEX explosion prevention and 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.
