Festo
549156
One-way flow control valve VFOV-LE-G18-Q6
The Festo 549156 is a manually actuated industrial component featuring a one-way flow control function for exhaust air with a G1/8 pneumatic connection port and a rotary knob adjusting element for threaded mounting. Operating with a working pressure range of 0.2 to 10 bar in an ambient and medium temperature range of -10 to 60 °C, this unit accommodates dried compressed air that can be lubricated or unlubricated in any assembly position. It delivers a standard nominal flow rate of 0 to 325 l/min in the flow control direction and 150 to 370 l/min in the non-return direction, constructed with NBR seals, a PA-reinforced rotary knob, and materials free of copper and PTFE.
