AR40-04BE-B: Modular Regulator, Integrated Pressure Control Core with Limit Indicator

Product Positioning
The AR40-04BE-B is a modular regulator from the SMC AR-B series, a core pressure control component within the F.R.L. air treatment unit family. Its most distinctive features are the built-in quick exhaust mechanism and the嵌入式压力表带限位指示器设计. It is specifically designed for automated equipment requiring precise setting and stabilization of air source pressure, along with the need for rapid exhaust of residual pressure on the outlet side. This product is widely used in packaging machinery, assembly lines, electronic processing, and general industrial automation.

Core Highlights: Quick Exhaust, Limit Indicator, Easy Installation

• Quick Exhaust Mechanism, Enhanced Safety
  • Incorporates a mechanism to quickly exhaust the outlet side pressure. It can rapidly释放下游气路残压 when the system stops or during maintenance, effectively preventing unintended operation and enhancing operational safety.
• Embedded Pressure Gauge with Limit Indicator,直观监控
  • Option “E” represents a square嵌入式压力表 with a limit indicator. The pressure gauge is embedded in the valve body’s front face, not only providing a clean appearance and saving space but also allowing operators to monitor the current pressure value at a glance.
  • The limit indicator (colored ring) can mark the normal working pressure range on the dial, enabling visual pressure monitoring and significantly improving on-site inspection efficiency.
• Includes Mounting Bracket, Stable Integration
  • Option “B” signifies附带安装托架, facilitating secure fixing of the valve to the equipment frame, simplifying installation, and enhancing system stability.
• Stable Pressure Adjustment, Prevents Misoperation
  • The adjustment knob is designed for easy operation, with a shape that is easy to touch with fingers when unlocking, ensuring operational convenience and safety.
  • The knob has a locking function, which can be locked after adjustment, effectively preventing unintended changes to the set value due to equipment vibration.
• Clear Specifications, Standard Ports
  • Body size is 40, corresponding to the 1/2 inch port size specification.
  • Port thread is Rc 1/2″ (PT taper thread), conforming to JIS B0203 standard.
  • Set pressure range is 0.05 to 0.85 MPa, maximum operating pressure is 1.0 MPa, maximum flow rate is 3000 L/min.
