The ARP is a modular style, direct operated precision regulator. A
locking adjustment knob allows the pressure to be set, and then locked
to prevent accidental setting changes. The ARP20/30/40 series is
available with a backflow function that exhausts the air pressure in
the outlet side reliably and quickly. Special applications include
(10-) clean room compliant, (20-)copper-free, fluorine-free, and (21-)
clean room compliant, copper-free, fluorine-free and silicon-free.
