In-line Flow Control Valves
BSP/Metric Series RFU - RFO
Panel/Wall-Mount Design: Meter-Out, Meter-In, Needle-Orifice
Thread Type: M5, G1/8, G1/4, G3/8 and G1/2
The unidirectional flow controllers are
equipped with M5, G1/8, G1/4, G3/8 and
G1/2 ports.
G1/8 and G1/4 ports are available with
two different types of adjustment (see
diagrams), whereas M5, G3/8 and G1/2
ports have just one type of adjustment.
All models can be panel or wall mounted
or they can be mounted on cylinders, as
required.
