FESTO VFOF One-Way Flow Control Valves
VFOF pressure valves when used with pneumatic drives adjust the flow and change the piston speed during the advance and return stroke. Restriction of the flow rate of compressed air is used to achieve this by using an adjustable annular gap in the housing, turning the regulating screw with an internal hex. Featuring integrated QS push in fittings and a robust metal design installation is simple and reliable.
