Function Fittings and Flow Controls
● 360° rotation of the banjo body around the bolt allows for ideal
positioning of tubing.
● Low profile and reduced physical size provide space saving
installations, while internal configuration provides the flow
capacity of much bulkier designs.
● Tapered adjustment needles with large adjustment ranges
provide linear flows and greater precision.
● Knurled adjustment knobs (w/screw driver slot) and lock nuts on
12 VA0 and 10 TA0 series provide finger tip adjustment. Tamper
resistance on the 12 VBO and 10 K51 is provided by a slotted
adjustment screw covered by a protective plastic cap.
● Direct mounting of flow controls on pneumatic actuators
minimizes the adjustment problems encountered due to the
compressibility of air in long tubing runs between the actuator
and control valving. Additionally, direct mounted flow controls
end the confusion over which actuator in a circuit is being
controlled.
● Metallic components are limited to nickel plated all brass
construction, eliminating the potential problems encountered
with products constructed of dissimilar metals.
● Adjustment needles and banjo bodies are retained, preventing
accidental loss of the needle or lock nut.
Right Angle (Banjo) Flow Controls
Operation:
Flow Controls are checked adjustable controls of the meter out type.
Compressed air passes freely into the push-in fitting portion of the flow
control, flowing past the check seal and entering the connected
component. In reverse flow conditions, air passes back into the flow
control and energizes the check seal. Air must now flow through the
metered passage controlled by the tapered adjustment needle of the flow
control, and finally exits through the push-in fitting end.
