SMC 21-ARP20-N02GH-3RZ precision regulator, REGULATOR, PRECISION

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 back flow 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.

• Direct operated precision regulator
• Sensitivity: within 0.2%F.S.
• 3 types of set pressure allow more freedom in designing a circuit
• Repeatability: within ±1%F.S.
• Backflow function available
