The R-900 Series regulators are designed for applications requiring
miniature size, light weight, and precision. 10-32 ports accommodate
a wide range of miniature fittings, including Airtrol Components
B-062 and B-125 barbed fittings.
FEATURES:
Twenty turn hysteresis free adjustment allows pressure settings
to 1" WC resolution.
Four
adjusting styles allow maximum design flexibility. The non-rising
stem is available with an attractive knob, or plain, allowing installation
of OEM knobs. Also available is a flush adjusting shaft, for applications
where pressure setting is changed less frequently. Factory pre-set
"tamperproof" models are also available.
Three
mounting options include panel mount, through a 9/16" hole (nut
included), and base mount, through 4 holes 0.125" dia. and manifold
mount(See drawings)
Plastic
construction - corrosion resistant wetted materials.
High
accuracy - Low effect of supply variation on output.
Low
cost - Perfect for OEM applications.

Note:
R-920 series regulators have "near zero" bleed to
atmosphere under normal operating conditions. Should any overshoot,
or downstream pressure increases occur, the unit will relieve
only what is necessary to stabilize the pressure setting.
Important: Proper filtration is a must to maintain correct
operation of the R-920 Series. Airtrol Components Inc. cannot
guarantee perfect "non-bleed" operation under any
circumstances. Consult with an Airtrol Application Engineer
for more information. |
