SMC 1/2 in G Pneumatic Regulator - 1 Mpa, AR40-F04-D 20L/min, G AR

This pneumatic regulator controls Air pressure in industrial pneumatic systems, providing a Compact solution for pressure adjustment and relief in automation and mechanical applications. It is designed for in-line use with G-threaded pipework and includes an overpressure exhaust mechanism to protect downstream equipment while operating across a wide ambient temperature range.

• Pressure setting range 0.05 to 0.85 MPa for precise control
• Maximum operating pressure 1.0 MPa to suit high-pressure loops
• Maximum flow capability 20 L/min for small high-flow tasks
• Die-cast zinc body offering mechanical robustness and stability
• Port size 1/2in G for straightforward G-thread installation

• Suitable for regulating Air supply to pneumatic actuators in automation
• Ideal for pressure control on test rigs requiring adjustable set points
• Used with pneumatic control panels in electronics assembly lines
• Can be used for conditioning instrument Air in mechanical workshops

It employs a relieving exhaust mechanism that vents excess downstream pressure to atmosphere when set pressure is reduced, enabling Rapid depressurisation of the downstream circuit.

The unit functions with media and ambient temperatures between -5°C and 60°C, provided there is no freezing of the medium.

The regulator is proof-tested to 1.5 MPa to verify structural integrity above normal operating pressure.

The internal passage is arranged for left-to-right flow through the body, with the adjustment knob oriented downwards for standard mounting.
