The SMC AR40-N04E-Z-B is a rugged, modular air pressure regulator from the AR-B series, equipped with a square embedded pressure gauge featuring a limit indicator. It operates with 1/2"" NPT ports and offers relieving flow (left-to-right) for rapid downstream depressurization via a downward exhaust design. Ideal for industrial FRL setups, it supports seamless connection to other SMC modules and includes a locking knob to prevent accidental adjustments.
- 1/2" NPT inlet & outlet, suitable for medium to high flow applications
- Embedded square gauge with limit indicator provides visual set-point feedback
- Relieving-type (Z option) ensures rapid depressurization when pressure drops
- Downward HNBR knob resists ozone exposure and locks to maintain settings
- Modular design supports system integration with FRL setups
- Maximum set pressure: 125?psi, with a maximum operating pressure of ~145?psi
